Hi
Today , the "service engine soon" light turn ON .
the code was P0332 - knock sensor 2 bank 2.

​what could be the reason ? only fault sensor ? Where it located ?

thanks

Could be the sensor, harness, connection at sensor or PCM.......rarely the PCM....

Since bank two, it will be in the block on the backside...look between tranny and engine....

Thank you
I'll check it .
You have the part number ? The sensor 1 and 2 it'* the same ?

2001 BUICK LESABRE 3.8L V6 Knock / Detonation Sensor | RockAuto

Anyone can have a guide to how to replace it ?

Has a hex head on it, so a flex head or crow'* foot is the best,,,just unscrews and screws in....there is a specific torque for it, but not sure what it is......

I have seen more harness/connection problems, than the sensor itself......

Only a scan tool can tell you if it is working, by tapping the engine in that area and looking for a change in timing....

After a week that the service light was ON, now it turn OFF .
I don't erase the code or replace the sensor . Maybe the problem solved ?
I order the sensor ... cancel it ?

Update
I replaced the knock sensor with brand new original sensor and the problem solved .
the replacing was easy , the access was from the bottom of the car .

thank you
