Knock Sensor

My SES light went on and it reads that its a knock sensor, i originally thought it was just a sensor in need of replacing. But if you listen carefully when youre accelerating, you can hear a VERY quiet clicking noise coming from the driver side of the engine. But it only does it if youre accelerating slowly, not when youre not moving or when you get on it. Any suggestions? Oh, and im not losing any power from it, in fact its not affecting the car at all. Advice??? Thanks guys.

he's saying that you wouldnt know if its actually affecting the cars performance if you dont have a scanner to read the knock retard. If the timing is being retarded due to detonation you will lose horsepower. even if its not detonating, the computer may still think it is if your hearing a clicking noise...usually a clicking inst enough to do this though. Get a scanner hooked up to it and check all the ground wires in the circuit
