    its a knock sensor.. you cant erase it because its hearing a knock,id try high octane gas first…if that doesnt help check sensor. Chev V8 motors all have noise in lifters. that should not set off sensor

    You can clear the code as many times as you want but if you keep ignoring the problem that is triggering the code it is only going to come back time and again.

    Fix the problem that is causing the Knock Sensor to register a fault and then no more worries.

    If you are not showing related codes ie: lean fuel,etc. then the problem should in the Knock sensor or the wiring going to it. Pull the plug and look for corrosion. Sometimes just pulling the plug and putting it back on will solve the problem..If all efforts fail, replace the sensor……….
