i was wondering you can delete the knock sensor codes just like the 02 sensor codes, l im throwin a knock sensor code, but i need to take emmissions and instead of pulling the car apart i thought it owuld be easier for now just to delete it so i can pass emissions and replace it while its hibernating for the winter

thanks in advance

yes knock codes can be deleted... but if you ever go WOT on your car I would not advise this...

if a knock sensor code is being set then there is a problem...

its saying low voltage, in the rear bank. so i was going to take emmissions but i might as well just replace it. i pressure washed my engine bay and i guess moisture got under neath there is a bulletin on it.

rear bank is unusual.. normallly it's a P0327 code .. the front bank gets flooded from natural causes ....

regardless... a knock code will toss you into the low octane tables AND pull timing ... so performance will DIE ...

what code is it setting ? P0xxx ?

i dont know, its been a while since ive driven the car, but i checked it at work with our HDS(honda diag scanner) and it says rear bank low voltage. and i looked up on all data about the dtc and it was saying that i need to put a wall of rtv(spelling) around the rear knock sensor and replace the knock sensor.

Condition

Some customers may comment on a mild to severe engine ping (commonly referred to as spark knock), usually worse during acceleration and/or an illuminated MIL. Upon investigation, the technician may find DTC P0332 set.

Cause

This condition may be the result of corrosion of the rear bank knock sensor due to water intrusion into the sensor cavity. This condition is more apparent on vehicles in which customers frequently wash the engine compartment.

Correction

Replace the rear bank knock sensor and build a dam (wall) around the sensor using RTV to divert water away from the sensor. Use the procedure and part number listed.
