code 52 knock sensor

[blue_supra_boy2]

bought a knock sensor but the bolt was alot smaller than the one on the engine

also the broken knock sensor said 76 on the bolt and the used one i bought said 75 ccould that be the reason im still having code 52

thanks,
Bryan

Check with a ohm meter the two knock sensor's wires to see if they are shorted to ground or shorted to positive with the harness unplugged from the ECU, If not then check continuity between the plug on the ECU and each knock sensor wire.. If all checks good then replace knock sensors.. Let me know if you need one I have some

Thanks

k
so the numbers on the nut shouldnt matter and the size of the nut either?
