Have you tested wiring between pcm and knock sensor?

Ask Your Own GMC Question
Customer reply replied 4 months ago
no
Customer reply replied 4 months ago
no, I have not
GMC Mechanic: Dan, Technician replied 4 months ago

I'd do that next. Problem is either knock sensor, wiring/connector, or PCM. Resistance on wire between knock sensor and PCM should be under 5 ohms resistance if high then repair/replace wire as needed. If good then replace the PCM, here is a wiring diagram to help with testing. My goal is to provide 5 star service so please let me know if you have any questions, thanks.
