OE Match knock sensor, it provides engine-vibration information used by the engine management system for knock detection.
Fits
- Porsche 993 1994-98
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.

Replacement crankshaft position sensor also known as an impulse or pulse sender. The crankshaft position sensor continuously monitors the rotational speed and position of the crankshaft as it spins. This information is transmitted as a signal to the engine control unit (ECU), which uses it to control key functions like ignition timing, fuel injection timing, and engine speed cues. Without a properly functioning sensor, the ECU may not be able to accurately time spark and fuel delivery, which can cause poor performance, rough idling, misfires, or failure to start.
The crankshaft position sensor is vital to engine management accuracy. If it fails or generates inconsistent signals, the ECU may not be able to properly time spark and fuel delivery, leading to:
• Poor engine performance
• Stalling, rough idle, or hesitation
• Hard starting or no-start conditions
• Fault codes related to timing or crank sensor errors
Replacing a worn or failed sensor restores accurate rotational feedback to the ECU, helping maintain engine drivability and reliability.
Replace the crankshaft position sensor if you notice:
• Engine misfires or rough idle
• Stalling or limp performance
• Engine won’t start but cranks
• Diagnostic codes related to crank position
• Inconsistent tachometer readings

Speed sensors, also referred to as pulse generators, are often the source of various errors. These sensors provide critical speed data required for the engine electronics to function properly, enabling regulation through feedback control. Depending on the vehicle's control system, pulse generators can serve as either camshaft or crankshaft sensors. Our spare parts program includes a wide range of pulse generators to meet your needs.
Starting with the 1996 model year, knock sensors, speed sensors, and temperature sensors were upgraded with improved plug connections. Using this conversion kit, you can easily update your vehicle’s wiring harness to the latest connector standard.
Please note: this part has been changed by Porsche and you will require the adaptor kit for plug connector if you are changing the original item.Diagram ref no 13
