P0332 DTC Code

Ok, well today coming home my SES light came on and this is the code i pulled out, its a knock sensor code, CK low bank 2, is this the front or rear knock sensor, and is there anything i can check or does it just mean i have to replace the knock sensor??


The only thing ive messed with under the hood besides washing the engine off was installing the new radiator and efan setup a few weeks ago, and the nelson performance harness wired into the a/c and pcm. but im almost sure this doesnt have anything to do with each other.


Thanks for the help.

do you have a tune?

bank 1 refers to the left side or front...bank 2 refers to the right side or back one

im pretty sure the sensors are front and back, just not sure why they list them as bank 1 and bank 2.

Well by reading that, it sounds like im going to be pulling the intake off and replacing the sensor.

Might as well replace both of them, at the same time. Is it necessary to replace the wiring harness for the sensors as well????


Thanks for all the help guys.

yeah that's what i was refering to as bank 2 is the back one and yes might as well replace both sensors while you are in there and the harness to be safe

Ok, does anybody know the part number for the knock sensor harness, all iim finding is the replacement connectors.


Also, is it possible to upgrade to LS2 style sensors that mount to the side of the block? I have two of these i bought awhile back to go on the engine im building for my Sonoma GT, so id just need to get the LS1 to LS2 conversion harness.

well doing a google search i came across this thread on here from 2003

And after reading this i think i maye have caused this problem, after i got the efans and bigger rad installed a few weeks ago i washed down the engine, so im wondering if the KR sensor was already on its way out.

Either way, i guess its time to replace the sensors and harness.

Ok, i have ordered two new knock sensors from a place in dallas off ebay, 2 for 45 bucks and 20 bucks for a new knock sensor harness, parts should be here next week, and next weekend i plan to get this fixed.

i hate to say it... but water 'could' have gotten in the valley, and ruined one.:spit:...happened to me anyway........
