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.

This knock sensor features the following specifications:

  • 100% New not remanufactured
  • Replaces dealer part numbers: 10456018, 1997699, 8104562880, 10456288, 1997699

still have obd1 code 43
while removing old knock sensor, the head stripped right off, tryed vice grips to remove the stripped bolt and theres no sign of it coming out. with the new sensor from 1aauto i had to locate a new hole in the block to secure it in. after doing so, the obd1 code 43 was still showing. faulty sensor? bad location on block? not sure, what i do know is i have both obd1 code 42 and 43, which points to the EST. time to search the web for information on that.

Bad or wrong sensor for my engine.
I received either a bad or wrong sensor for my 454. I went to the local NAPA and got one that works. A total waste of $25.00.. lesson learned.... I won't be using 1A auto parts again nor will I recommend them!
