Silentkillzr Posted October 5, 2012 Author Report Share Posted October 5, 2012 (edited) Alright, your going to like this story lol.... So i went back to oreillyauto with the 'new' bwd sensor i got. They pulled out the replacement they had ordered the night before, i tested it in front of the managers face and told him it was bad too. He then says "I really dont see how factory replacement parts would be bad.. your doing it wrong, knock sensors dont test out ohms..." I instantly get mad and tell him how you test them, he says im completely wrong, i say regardless i dont want your garbage parts, give me a refund. Needless to say i wont be going to that store again. Then I went to my closest GM dealer for shits and giggles. They dont have one in stock and the price to order it is $91. I think this is a tad overpriced. I am not sure what todo here. Can you give me some advise? maybe link me to the exact part i need? I am out of ideas.

RobertISaar Posted October 5, 2012 Report Share Posted October 5, 2012 is your meter perhaps at fault? anyways, "proof" that it's tested via resistance is in the factory flowchart for the DTC43 error, step 3, making sure it's between 3.3 and 4.5 Kohms. the knock sensor circuit is pin C20. C is the blue connector. pins are numbered 1-16 in one row, 17-32 in the other. that means C20 will be the 4th in the 17-32 row. there should be some really tiny numbers on the face of the colored plastic to guide you at that point. should see ~3900 ohms resistance from the pin to a good, known ground. have you tried measuring resistance with the connector on and pulling the ECM connector itself and measuring from the pin?

Silentkillzr Posted October 5, 2012 Author Report Share Posted October 5, 2012 I can try the pin, but i tested all of these with two different multimeters which both work. I will try measuring via pin and get back to you soon Quote Link to comment Share on other sites More sharing options...
Silentkillzr Posted October 10, 2012 Author Report Share Posted October 10, 2012 I didnt get around to measuring pin resistance yet, I just ordered a new Delphi knock sensor from Rock auto. Delphi was the company that originally made it for the car i guess so im going to have to trust that lol. Once i get this new one in and hooked up ill read out that pin if its not working already. So excited i just want to drive my car! Quote Link to comment Share on other sites More sharing options...
Silentkillzr Posted October 11, 2012 Author Report Share Posted October 11, 2012 YESSSS!!!! i got the delphi knock sensor in today, tested before install ~3900 ohms perfect, put it in, no more SES lights, car runs fucking amazing!!!! Thank you so much robert for your help, i love you. You should get member of the year for this! Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted October 11, 2012 Report Share Posted October 11, 2012 amazing. you went through how many new but bad sensors? Quote Link to comment Share on other sites More sharing options...
Silentkillzr Posted October 11, 2012 Author Report Share Posted October 11, 2012 (edited) Basically i dicked around with 5 sensors before i found one that worked. Go rockauto.com for quality parts. Just drove the car in the country for a little while, 22mpg city/hwy mixed. And its actually pretty snappy and quick now!
