Frequently asked questions

What does the knock sensor do on the V8 petrol engine?
The knock sensor detects combustion knock (detonation) through cylinder-block vibration and signals the engine control module, which retards ignition timing to protect the engine. It is fitted to the 4.0L and 4.6L V8 petrol engines.
Where is the knock sensor located?
The knock sensor mounts on the cylinder block of the V8 petrol engine, where it can pick up vibration from combustion. It is part of the engine management system on the 4.0L and 4.6L V8 petrol applications.
Which vehicles use this knock sensor?
This knock sensor fits the Defender (1986-2006), Discovery 1 (1989-1998), and Range Rover P38 (1994-2001), with the 4.0L or 4.6L V8 petrol engine. It suits those V8 petrol applications running engine knock control.
What are the signs of a failed knock sensor?
Typical signs include an engine warning light, reduced power, and poorer fuel economy as the ECM defaults to conservative ignition timing. On the 4.0 and 4.6 V8 petrol a faulty knock sensor can also cause audible pinking under load.
