How to Bypass a Chevy Knock Sensor

Your knock sensor is an electrical device on your truck, car or Sport Utility vehicle that detects knocks in your engine caused by premature detonation of the air-fuel mixture as it enters the cylinder head. When knock sensors start to go bad, you may hear a pinging or loud knocking coming from your engine. If you ever need to bypass your knock sensors, the most direct way of doing so is to simply disconnect them.

STEP 1 - Pull your hood latch. Open your hood. Place your socket set over the bolt holding your negative battery cable. Turn the socket to the left to loosen the bolt. Slip the cable off.

STEP 2 - Find the knock sensor on your car, truck or SUV. The knock sensor is mounted on front of your engine, near the fuel injector. On some vehicles you may have to remove hoses or the air box cover to access your knock sensor.

STEP 3 - Unplug the wiring harness from your vehicle's knock sensor once you have found it.

STEP 4 - Loosen and remove the retaining bolt holding your knock sensor. Remove the knock sensor.
