I forget the code number by came up knock sensor. I purchase a new knock sensor and sensor wire. I cut out the burn wire replace with new wire and sensor. I cleared the code getting C12. After starting the car the same knock senor code would reappear in about 15 second. I then purchase a AC DELCO senor with wire installing and clearing code. Start the car and getting the same code just after starting. any suggestion will be great

U sure u bought the correct sensor? There?s a difference between ZR and regular C4. I forget the value, think its 3.2K ohms, but u can check resistance on sensor to make sure. Check w Jerry at Jerry?s Gaskets also.
