Knock sensors new still not working with code Just built an LS2 402 stroker, installed 2 new AC Delco knock sensors in the sides of the block. I also got the Racetronix wiring kit to lengthen the wires. I ohmed the wires all the way back to the main PCM connection and they came out good. Still getting a knock sensor DTC. I had this code as well with the LS1 in the car, but turned if off until I could fix it.
Since I have a new motor, 2 new sensors and a known good harness I turned the code back on, but it is still throwing the code. Is it possible the PCM is bad. I thought about taking it apart and checking for bad solder joints.
