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.

does this part stop it from skipping , and choking?
mary k on Jan 31, 2017
BEST ANSWER: The knock sensor is meant to provide the engine's computer with a signal based on the vibration of the engine caused by detonation. When spark knock occurs, the computer uses the signal from this part to retard timing and may cause a check engine light code to appear on your dash. If your vehicle has skipping and choking, there would be a separate reason which we suggest having a local automotive repair shop diagnose. You may also view automotive forums for your vehicle to see if other owners have had a similar issue and what they have done to fix the issue.
