I've popped the code P0332 knock sensor 2 several times. It will reset and stay off for a while. Last time it came on was after a brief run at highway speeds.

I'm thinking it's a bad sensor and not an actual knock. Engine is really smooth.

Thoughts on using sensors from advance versus from GM?? Advance has lifetime warranty.

Anyone have video or can point me to video of someone doing this in a van. My research says I'll have to take intake off. My guess is I will go in through engine cover in passenger compartment.

Appreciate any tips on doing this repair.
