- Porsche 958 Cayenne V6 3.6L Petrol (300Hp) 2010-17
Restore accurate fuel-mixture monitoring and dependable engine-management performance with this OE Match Right Lambda Oxygen Sensor. Designed for compatible Porsche applications, this sensor is specified for the RIGHT side, BEFORE the catalytic converter.
Fits:- Porsche 958 Cayenne V6 3.6L Petrol (300Hp) 2010-17
Diagram Ref No 18
Also known as an upstream, pre-cat or O2 sensor, the lambda sensor measures the oxygen content remaining in the exhaust gases after combustion. This information is sent to the engine control unit (ECU), allowing it to determine whether the engine is operating with a rich or lean air-fuel mixture and make precise adjustments to fuel delivery.
Because this sensor operates before the catalytic converter, it plays an important role in closed-loop fuel control. Accurate readings help maintain efficient combustion, responsive engine performance, appropriate fuel consumption and controlled exhaust emissions.
Lambda sensors operate in a particularly demanding environment, exposed to extreme exhaust temperatures, vibration and combustion deposits. Over time, the sensing element can become contaminated or slow to respond, while the heater circuit, wiring or electrical connector can also deteriorate.
This OE Match Right Lambda Oxygen Sensor provides a high-quality replacement for a worn, contaminated, damaged or failed original sensor.
What This Product Does:
- Is designed for the RIGHT-side application.
- Is positioned BEFORE the catalytic converter.
- Measures oxygen content in the exhaust gases.
- Sends exhaust oxygen information to the ECU.
- Helps determine whether the air-fuel mixture is rich or lean.
- Allows the ECU to make continuous fuel-delivery corrections.
- Supports accurate closed-loop mixture control.
- Helps maintain efficient combustion.
- Supports smooth throttle response and engine performance.
- Helps optimise fuel consumption.
- Contributes to correct exhaust emissions.
- Helps protect the catalytic converter from problems associated with incorrect fuelling.
- Replaces a slow, contaminated, damaged or failed lambda sensor.
- Provides an OE Match alternative for compatible Porsche applications.
Symptoms Of Wear Or Failure:
- Check engine or engine-management warning light.
- Lambda or oxygen sensor-related diagnostic fault codes.
- Bank-specific rich or lean mixture fault codes.
- Increased fuel consumption.
- Rough or unstable idle.
- Hesitation during acceleration.
- Poor throttle response.
- Reduced engine performance.
- Engine running excessively rich or lean.
- Strong fuel smell from the exhaust.
- Increased exhaust emissions.
- Failed emissions testing where applicable.
- Intermittent engine-management warnings.
- Slow sensor response during diagnostic testing.
- Implausible or inconsistent lambda readings.
- Oxygen sensor heater circuit faults.
- Damaged wiring, insulation or electrical connectors.
Why Replacement Matters:
- The pre-catalytic converter lambda sensor provides essential feedback for controlling the engine's air-fuel mixture. The ECU relies on this information to make continual fuel-delivery adjustments as engine speed, load and operating conditions change.
- As a lambda sensor ages, its response may become progressively slower or less accurate without immediately failing completely. This can result in less precise mixture control and contribute to increased fuel consumption, reduced performance, unstable running and higher emissions.
- Incorrect fuelling can also affect the catalytic converter. An excessively rich mixture may allow unburned fuel to enter the exhaust system, increasing catalyst temperatures and potentially shortening catalytic converter life.
- A completely failed sensor may cause the ECU to substitute calculated values or adopt a fallback operating strategy. The engine may remain driveable, but efficiency, emissions and performance can be compromised.
- Because it is specified for the right-side, pre-catalytic converter position, correct sensor location is particularly important on engines equipped with multiple exhaust banks and lambda sensors.
- Replacing a defective sensor with this OE Match Right Lambda Oxygen Sensor helps restore accurate mixture feedback, efficient combustion and dependable engine-management performance.

Diagram Ref No 7
Also known as an upstream, pre-cat or O2 sensor, the lambda sensor provides essential feedback to the engine control unit (ECU). By measuring residual oxygen in the exhaust stream, it enables the ECU to determine whether the engine is operating with a rich or lean air-fuel mixture and make continuous corrections to fuel delivery.
As a pre-catalytic converter sensor, it has an important role in closed-loop fuel control. Accurate readings help maintain efficient combustion, responsive performance, appropriate fuel consumption and controlled exhaust emissions.
Lambda sensors operate under demanding conditions and are continually exposed to extreme exhaust temperatures, vibration and combustion deposits. With age, the sensing element can become contaminated or slow to respond, while the internal heater, wiring or electrical connections may also deteriorate.
This OE Match Lambda Oxygen Sensor provides a high-quality replacement for a slow, contaminated, damaged or failed original sensor.
What This Product Does:
- Measures oxygen content within the exhaust gases.
- Is designed for installation before the catalytic converter.
- Sends exhaust oxygen information to the ECU.
- Helps determine whether the engine is running rich or lean.
- Allows the ECU to make accurate fuel-delivery adjustments.
- Supports closed-loop air-fuel mixture control.
- Helps maintain efficient combustion.
- Contributes to smooth and responsive engine performance.
- Helps optimise fuel consumption.
- Supports correct exhaust emissions.

- Failed emissions testing where applicable.
- Intermittent engine-management warnings.
- Slow sensor response shown by diagnostic equipment.
- Implausible or inconsistent lambda readings.
- Oxygen sensor heater circuit faults.
- Damaged wiring, insulation or electrical connectors.
Why Replacement Matters:
- The lambda sensor positioned before the catalytic converter is a key feedback component within the engine-management system. The ECU relies on its signal to continually fine-tune the amount of fuel delivered to the engine.
- As a lambda sensor ages, it may become slower to react to changes in exhaust oxygen content. A sensor does not necessarily have to fail completely to affect engine operation; delayed or inaccurate readings can result in less precise fuel corrections.
- Poor mixture control can contribute to increased fuel consumption, reduced performance, unstable running and higher exhaust emissions.
- Incorrect fuelling can also place additional stress on the catalytic converter. If the engine runs excessively rich, unburned fuel can enter the exhaust system and increase catalyst temperatures, potentially shortening catalytic converter service life.
- A failed sensor may cause the ECU to use substitute values or adopt a fallback strategy. Although the engine may continue to run, fuel efficiency, emissions and performance may be compromised.
- Replacing a defective sensor with this OE Match Lambda Oxygen Sensor helps restore accurate mixture feedback, efficient combustion and dependable engine-management operation.

Diagram Ref No 6
Also known as an upstream, pre-cat or O2 sensor, the lambda sensor provides critical feedback to the engine control unit (ECU). By monitoring residual oxygen in the exhaust stream, it allows the ECU to determine whether the engine is running richer or leaner than intended and make continuous adjustments to fuel delivery.
Accurate pre-catalyst lambda sensor information is important for maintaining efficient combustion, responsive performance, fuel economy and emissions control. Unlike a downstream sensor, which is commonly used to monitor catalytic converter performance, the before-catalytic-converter sensor has a direct role in fuel-mixture regulation.
Lambda sensors operate in an extremely demanding environment and are continually exposed to high exhaust temperatures and combustion by-products. Age, contamination, wiring damage or deterioration of the sensing element can eventually cause slow, inaccurate or failed readings.
This OE Match Lambda Oxygen Sensor provides a high-quality replacement for a worn or defective pre-cat sensor, helping restore accurate mixture feedback and correct engine-management operation.
What This Product Does:
- Measures oxygen content in the exhaust gases.
- Is positioned before the catalytic converter.
- Provides air-fuel mixture feedback to the ECU.
- Helps the ECU determine whether combustion is rich or lean.
- Allows continuous adjustment of fuel delivery.
- Supports accurate closed-loop fuel control.
- Helps maintain efficient combustion.
- Contributes to consistent engine performance and throttle response.
- Helps optimise fuel consumption.
- Supports correct operation of the emissions-control system.
- Helps protect the catalytic converter from problems associated with incorrect fuelling.
- Replaces a slow, contaminated, damaged or failed oxygen sensor.
- Provides an OE Match replacement for compatible Porsche applications.
Symptoms Of Wear Or Failure:
- Check engine or engine-management warning light.

- Failed emissions testing where applicable.
- Intermittent engine-management faults.
- Slow or implausible lambda sensor readings during diagnostic testing.
- Damaged sensor wiring or electrical connector.
- Heater circuit-related sensor faults where applicable.
Why Replacement Matters:
- The pre-catalytic converter lambda sensor is a key feedback device for the engine's fuel-management system. When operating correctly, it allows the ECU to continually fine-tune the air-fuel mixture as driving conditions change.
- As a lambda sensor ages, its response can become slower even before it fails completely. Delayed or inaccurate feedback may cause the ECU to make less precise fuelling corrections, potentially resulting in increased fuel consumption, reduced performance and higher emissions.
- Incorrect fuelling can also affect the catalytic converter. An excessively rich mixture may allow unburned fuel to enter the exhaust, potentially causing the catalyst to operate at abnormally high temperatures. Persistent lean-running conditions can also contribute to poor engine operation and increased combustion temperatures.
- A failed sensor may cause the ECU to rely on substitute values or an alternative control strategy. While the vehicle may continue to operate, performance, efficiency and emissions can be compromised.
- Replacing a defective component with this OE Match Pre-Catalytic Converter Lambda Oxygen Sensor helps restore accurate mixture feedback, efficient combustion and dependable engine-management operation.

- Temperature-related warning behaving incorrectly where applicable.
- Sensor-related diagnostic fault codes.
- Visible damage to the sensor.
- Corroded or contaminated electrical connections.
- Broken or damaged sensor wiring.
- Physical damage caused by road debris or previous repairs.
Why Replacement Matters:
- An exterior temperature sensor provides useful information about the conditions surrounding the vehicle. An inaccurate sensor can make the displayed temperature misleading and reduce the driver's ability to recognise potentially cold or changing road conditions.
- Where the vehicle provides a low-temperature or frost warning, an incorrect sensor reading may cause the warning to appear at the wrong time or prevent it from operating as expected.
- Depending on vehicle specification, ambient temperature information may also be referenced by other electronic systems. An implausible sensor signal can therefore potentially affect functions beyond the temperature display itself.
- Sensor problems are often caused by age, corrosion or physical damage. Because the sensor is exposed to external conditions, its wiring and connector can also deteriorate over time.
- Replacing a defective component with this OE Match Exterior Temperature Sensor helps restore accurate ambient temperature information and dependable operation of systems that use the exterior temperature signal.

Restore accurate engine speed and crankshaft position monitoring with this OE Match Crankshaft Position Sensor, specified for the cylinders 6–10 application on compatible Porsche engines.
Fits:- Porsche Carrera GT 2003-06
Diagram Ref No 40
The crankshaft position sensor is a critical engine-management component. It monitors the rotational position and speed of the crankshaft and sends this information to the engine control unit (ECU). The ECU uses this signal to coordinate essential functions such as ignition timing and fuel injection.
Accurate crankshaft position information allows the engine management system to determine precisely where the engine is within its operating cycle. If the sensor signal becomes weak, intermittent or disappears completely, the ECU may be unable to control ignition and injection correctly. This can lead to difficult starting, misfires, poor running or a complete no-start condition.
Electrical sensors can deteriorate through age, repeated heat cycles, vibration, damaged wiring or connector problems. Some failures can also be temperature-related, with the sensor working correctly when cold but becoming unreliable once the engine reaches operating temperature.
This OE Match Crankshaft Position Sensor provides a high-quality replacement for a faulty or damaged sensor, helping restore accurate engine timing information and dependable engine-management operation.
What This Product Does:
- Monitors crankshaft rotational position.
- Measures crankshaft speed or engine RPM.
- Sends crankshaft position information to the ECU.
- Helps the ECU determine correct engine timing.
- Supports accurate ignition control.
- Supports correctly timed fuel injection.
- Helps maintain smooth and consistent engine operation.
- Provides essential information during engine starting.
- Supports accurate engine-management diagnostics.
- Helps maintain reliable performance across changing engine speeds and loads.
- Replaces an intermittent, damaged or failed sensor.
- Is specified for the applicable cylinders 6–10 position/application.
- Engine cranks but does not start.
- Intermittent starting problems.
- Extended cranking before the engine starts.
- Engine unexpectedly cutting out.
- Engine stalling when hot.
- Engine restarting after it has cooled down.
- Intermittent loss of engine power.
- Rough or inconsistent engine operation.
- Engine misfires.
- Hesitation during acceleration.
- Check engine or engine-management warning light.
- Crankshaft position sensor-related diagnostic fault codes.
- Engine speed signal disappearing during diagnostic testing.
- Tachometer or RPM information behaving abnormally where applicable.
- Damaged sensor wiring or electrical connector.
- Heat-related intermittent sensor failure.
Why Replacement Matters:
- A sensor that fails completely can potentially prevent the engine from starting. An intermittent sensor can be more difficult to diagnose because the vehicle may operate normally before suddenly stalling or refusing to restart.
- Heat-related deterioration is particularly troublesome. A failing sensor may work when the engine is cold but lose its signal as temperatures rise, potentially causing the engine to cut out during operation.
- An inaccurate or unstable signal can also contribute to misfires, poor performance and engine-management warning lights.
- Because crankshaft position information is directly related to ignition and injection control, unresolved sensor faults can compromise overall engine reliability and may leave the vehicle unable to start.
- Replacing a defective component with this OE Match Crankshaft Position Sensor helps restore accurate engine speed and position information, dependable starting and correct engine-management operation.

Restore accurate combustion monitoring and dependable engine-management operation with this OE Match Knock Sensor. Designed for compatible Porsche applications, the knock sensor monitors engine vibrations associated with abnormal combustion, allowing the engine control unit (ECU) to respond when detonation or engine knock is detected.
Fits:- Porsche 95B.1 Macan Petrol 2.0L (237Bhp) 2014-18
Diagram Ref No 21
During normal operation, the ECU continually adjusts engine parameters to achieve an effective balance between performance, efficiency and engine protection. The knock sensor plays an important role in this process by detecting characteristic vibration frequencies produced when combustion does not occur as intended.
When knock is detected, the ECU can adjust ignition timing and other applicable operating parameters to reduce detonation. This helps protect internal engine components from the excessive pressure and temperature associated with prolonged engine knock.
A faulty knock sensor may provide an incorrect, intermittent or missing signal. This can trigger an engine-management warning and may cause the ECU to adopt more conservative ignition settings, potentially resulting in reduced performance or efficiency.
This OE Match Knock Sensor provides a high-quality replacement for a defective or damaged original sensor, helping restore accurate knock detection and correct engine-management response.
What This Product Does:
- Detects engine vibrations associated with detonation or abnormal combustion.
- Sends combustion vibration information to the ECU.
- Helps the engine-management system identify engine knock.
- Allows ignition timing to be adjusted when knock is detected.
- Helps protect internal engine components from damaging detonation.
- Supports optimum ignition timing under changing operating conditions.
- Helps maintain smooth and efficient combustion.
- Supports consistent engine performance and throttle response.
- Allows the ECU to adapt appropriately to engine load and operating conditions.
- Replaces a failed, damaged or unreliable knock sensor.
- Provides an OE Match alternative for compatible Porsche applications.
Symptoms Of Wear Or Failure:
- Check engine or engine-management warning light.
- Knock sensor-related diagnostic trouble codes.
- Reduced engine power. Sluggish acceleration.
- Poor or inconsistent throttle response.
- Engine entering a reduced-performance or protective operating strategy.
- Increased fuel consumption.
- Rough or inconsistent engine operation.
- Audible pinging or knocking during acceleration.
- Knock particularly noticeable under heavy engine load.
- Intermittent engine-management warnings.
- Damaged knock sensor wiring or connector.
- Diagnostic testing showing an implausible, intermittent or missing sensor signal.
Why Replacement Matters:
- Engine knock or detonation occurs when combustion inside the cylinder becomes abnormal, creating uncontrolled pressure waves rather than the intended smooth combustion process.
- Persistent detonation can expose pistons, bearings, cylinder walls and other internal engine components to increased mechanical and thermal stress. Severe or prolonged knock can potentially contribute to expensive internal engine damage.
- The knock sensor helps prevent this by giving the ECU the information needed to identify abnormal combustion and make appropriate ignition adjustments.
- If the sensor fails or sends unreliable information, the ECU may no longer be able to determine accurately whether knock is occurring. Depending on the engine-management strategy, it may compensate by using conservative ignition timing to provide additional engine protection.
- While this can reduce the risk of damage, it may also result in reduced power, poorer throttle response and increased fuel consumption.
- A defective sensor can also create persistent diagnostic faults or warning lights, making it more difficult to identify other genuine engine-management problems.
- Replacing a failed sensor with this OE Match Knock Sensor helps restore accurate combustion monitoring, appropriate ignition control and the engine protection functions built into the management system.
