Information
Impulse / speed reference sensor.
Fits:
Porsche 964 1989-94 (requires ADAPTORKIT01)
Porsche 993 1995-98 (requires ADAPTORKIT01)
Porsche 996 Turbo 2001-05 (6-speed Manual transmission)
Please note: this part has been changed by Porsche and you may require adaptor kit for plug connector.
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

Information
Crankcase knock sensor.
This OE-Match knock (detonation) sensor is built to factory specifications for precise fit and performance. It detects engine knock or pinging and relays signals to the ECU, allowing it to adjust ignition timing for optimal operation.

Diagram ref no 17
Mounted directly into the engine block, typically on a cylinder bank or block surface. Positioned to sense vibration from the combustion process (often near the pistons or cylinder heads).
• Detects abnormal combustion (knock) by measuring vibration in the engine block.
• Transmits voltage signals to the ECU so it can retard timing to avoid engine damage
• Helps preserve engine health, efficiency, and performance by preventing detonation
A failing or degraded knock sensor can cause misfires, rough idle, reduced power, poor fuel efficiency, or illuminated check engine lights. Without accurate knock sensing, the ECU may not properly adjust timing, risking engine damage under load. Installing an OE-Match replacement restores correct sensitivity, supporting optimal combustion and engine reliability
