Knock sensor code 34.
This is the code I am getting. So far I have done everything the fsm says to check for sensor function. I have 567k ohms resistance.This shows good for the knock sensor. I checked for continuity from the knock sensor connector and pin 54 (97 ser computer) and I have 6 ohms resistance. good continuity.
I will be checking another knock sensor later to test to see if that is a problem. right now I am going to make sure I have good signal at idle. I think I am supposed to have 2.5V at idle? AC current right?
Also, I rewired the sensor a while back to extend the harness, I noticed the signal wire is wrapped with another wire. I am guessing this is to reduce noise in the circuit? It must not be completely necessary to have that wire extend all the way to the sensor, because the signal wire to the ecu is unshielded as well.
Anyone have any suggestions? The knock sensor is not very old and was torqued over the spec I think. I am going to try another mounting place for it because the stock location is a pita.
any comments appreciated.
