Service Engine light

[02TAHOELT]

Ok, so last night am driving to work and my Service Engine Light comes on. So when i get to work i Scan it Code P0332 - Knock Sensor 2 Circuit Low Input (Bank 2). So i erase the code, truck sits at work ALL Night. This morning Coming home from work it was fine passed by Autozone, went thru Car Wash, Then i get on the highway driving Home and floor it Running good so far, when i let off a few seconds later there's that light again. Scanned it again when i got home Same Code P0332 - Knock Sensor 2 Circuit Low Input (Bank 2). Is my knock sensor bad, Can i use a different knock sensor (from a different vehicle). Because i know my buddy had a Impala SS and we ended up putting a Camaro or LT4 knock sensor on there.

My Truck does have a Custom Tune, any help please

After you have exhausted all diagnosing, checking wires, the connection, performing resistance and voltage tests on the sensor itself, you might end upo just replacing the knock sensor.

Sometimes knock sensors can be a pain. They can be carboned up, type of gas used or just old,

I've had the check engine light come on when I didn't properly tighten the gas cap. Once gas cap was on correctly it took approximately 25 mi for the light to go away.

But that wouldn't give you a Knock Sensor code
