OE Match knock sensor, it provides engine-vibration information used by the engine management system for knock detection.
Fits

Check fitment for your specific vehicle (model, year, engine) before ordering.
Diagram reference No: 7.
What This Product Does
The sensor monitors vibrations associated with detonation and passes a signal to the engine control unit. This information allows the control unit to adjust ignition timing when knock is detected. It is a knock-detection component, not an engine-speed or crankshaft-position sensor.
Functions
- Detects engine vibrations associated with knock.
- Provides a signal for engine-management assessment.
- Supports knock-related ignition timing adjustment.
Technical Details
- Brand: OE Match.
- Part reference: 99360614100.
- Existing catalogue cross-reference: BOSCH 0261231118.
Symptoms of Fault
- Recurring knock-sensor fault codes.
- Reduced engine response where ignition timing has been retarded.
- Cracked wiring insulation or corrosion at the connector.
These signs are not conclusive evidence of sensor failure. Inspect the wiring and connections and confirm the diagnosis before replacing the component.
Why Replacement Matters
A defective sensor or damaged connection can interrupt the knock signal used by the engine management system. Replacing a confirmed faulty component addresses that signal fault; wiring defects must also be repaired rather than left unresolved.
FAQs
- Does a fault code confirm that the sensor needs replacing?
No. Check the connector, wiring and sensor signal before deciding which component has failed. - What should be checked before fitting?
Confirm the vehicle application and original reference, then follow the model-specific installation procedure. - Does the recorded quantity mean this is a pair?
No. The diagram specifies two sensors on the vehicle, not the contents of this product.

The Crankshaft Position Sensor (CKP) product ref: 95560614700, 95560643300, 0261210178 is a critical engine management component that monitors the exact rotational position and speed (RPM) of the crankshaft. This information is essential for the engine control unit (ECU) to correctly time spark ignition and fuel injection events. On Porsche Cayenne 955 and 957 models, a reliable crankshaft position sensor ensures precise engine timing, optimal performance, smooth running, and efficient fuel combustion.

Why This Should Be Replaced
The crankshaft position sensor can fail over time due to heat cycling, vibration, contamination, or electrical wear. When the sensor starts to degrade or fails outright, the ECU loses the ability to accurately determine engine speed and position, which directly impacts performance and drivability.
Replacement is recommended when the sensor is faulty or showing signs of wear, as continued operation with a compromised CKP sensor can lead to more serious engine issues, driveability problems, and component strain.
Common Symptoms of a Failing Crankshaft Position Sensor
A failing or failed crankshaft position sensor typically causes one or more of the following symptoms:
- Engine misfires or runs unevenly
- Hard starting or no start condition
- Stalling, particularly at idle or low speed
- Check Engine Light (CEL) with CKP-related fault codes stored
- Loss of power / hesitation under acceleration
- Irregular tachometer behaviour or incorrect RPM reading
If left unresolved, these issues can lead to increased fuel consumption, catalytic converter damage, and an overall unsafe driving experience.
