Hi folks
the SES light shown everytime , code P0332 , I reset it and it come back after few KM .
I tried to clean the sensor , it was dirty , but the code come back .
how can I check the wire ? Or the sensor (it new) ?
There is any guide/test that can help me find the problem ?
there and possiblity that sensor 1 do the problem but the code point on sensor 2 ? Cause from what I saw the sensor 1 is old ...
Thank you

Hi
today I switch between bank 1 and 2 sensors . and reset the code.
after while the code came back P0332 , so it not the sensor , how can I check the wires ? Where it connected ?

You will disconnect your negative battery cable first first.......then disconnect the C1 Blue connector from the PCM.......disconnect the knock sensors...might as well do both at this time....with meter on ohms, attach one lead to C1, terminal 34(lt blue) and the other end to the knock sensor 2 harness........should read zero ohms......then take one of the leads and attach it to the neg battery cable.....should read infinite ohms....
Do the same for C!, terminal 33(dk blue) and the harness at sensor 1......if results are ok, and all terminal connectors are ok, and since you have swapped/changed knock sensors and still get the code, then it is the PCM.......

Thank you TechII
today I checked the wire from the PCM to the sensor . After the gray connector of the knock sensor I found one more connector , black one , I did OHM test before and after this connector and it was disconnected . I did a test from after the connector to the PCM and I saw 0.00 OHMS .
I cancel the faulty connector and reset the code .
I think I found the problem ... hopefully it end now.
I will update in the next days ..
I appreciate your help TechII . Thank you very much !!
