This replacement Engine Knock (Detonation) Sensor is just what you need to get your vehicle in good running order again!

A knock sensor is like a small electronic microphone that is usually attached to the engine block and listens for a couple of things that a engine might do. One thing it listens for is pre-ignition or knocking inside the engine usually caused by a few issues including dirty gas, wrong engine timing low octane fuel, wrong air / fuel mixture, and also by the wrong spark plugs. It also listens for engine run on which happens when the vehicle is turned off, but tries to keep running until it stalls. Once a noise is detected, the knock sensor sends a signal to the cars computer which in turn will retard the timing at 2 degree intervals until it corrects the issue. If the knock sensor fails, it can seriously damage the engine, as continuous pre-ignition could cause melting or fractures in the pistons just to name a few.

  • 100% New not remanufactured

Can this knock sensor be relocated on a 03 honda accord??
Leo A September 19, 2017
Yes, this part is a fit for the 2003 Honda Accord with the V6 3.0L engine.
Alex P September 19, 2017
There is no information available on relocating this sensor, so we would have to say it is not possible while still getting the OE specified readings from the sensor.
Alex P September 19, 2017
The best recommendation we may make is to use a screw extractor kit which is available at a local auto part store to ensure that you do not make any additional holes in the engine block, or near the knock sensor current location.
