Knock Sensor buying guide
Why replace this part?
The knock sensor detects engine detonation, allowing the ECU to retard ignition timing before piston or bearing damage occurs. A faulty knock sensor leaves the engine vulnerable to detonation damage or causes excessive timing retard that reduces power.
Signs you need a replacement
- Check engine light with P0325–P0334 codes
- loss of power and performance under load
- increased fuel consumption
- audible pinging or knocking when accelerating
- poor throttle response
When to replace
No fixed interval — replace on failure. Knock sensors can fail from heat cycles or mechanical vibration over high mileage.
