I have a code po332 on my 99 lq4 motor. It's a knock sensor code. It has new knock sensors in it and the motor has never gotten wet. What could be causing this to happen? Also would this cause a low power problem?

check wiring. maybe the knock sensor wire rubbed through and is grounding out somewhere. that could definitely cause a low power issue, the PCM will pull all your timing if it sees a crazy knock signal
