How to diagnostic a P0333 bank 2 knock sensor

Hi,

It's been a while since I'm been here, but I really need your help.

I recently got a check engine e light, the code was p0333 for the bank 2 knock sensor. My question is.

Is there a way to visually inspect the condition of the wiring, (I read several time that this may be cause by rodent chewing).

I also read that the sensor is very deep in the engine. I really don't want to go that way without determine that is the problem.

Thank you

 

Did you ever figure this out? I'm having the same issue.

 

If it is a rodent chewing on the wires then a lot of the top end of the motor has to come off to get to the wires. I hate chipmunks now.

 

I have mine scheduled to go into the shop next week. I'm afraid it will be rodents too! I hate them!

 

If they have to take the top end off it's expensive. A lot of labor for a $100 harness.
