anyone know if this could be both sensors or a bad harness? anyone know how to test the sensors and harness?
i have the top end of the motor apart cause i have the P0325 Knock Sensor 1 Circuit Malfunction (Bank I or Single Sensor) and
P0330 Knock Sensor 2 Circuit Malfunction (Bank 2)codes. when i check the resistance of the cold knock sensors i get no reading like its an open circuit. i tried tapping the sensor while checking the resistance and still got the open circuit reading like before. thanks for the help
Sorry, I am not answering questions you are asking ....
Based on my experience ... after all the energy and time spent taking the things apart, it is no longer worth finding the only real problem. Simply replace all knock sensors and replace the wire-harness-connectors. Think if you replace the failed part and say in 2 months after you put the whole thing back together the next sensor fails ..... argh
visually check the harness, that code is for the sensor itself thou.... the repair manual says to do a continuity check from the base of the sensor to the connector. OFF LIMITS means the sensor is OK.
I recently had the code for bank 2, except the cause was excessive pinging... it was so bad it made the ECU think the knock sensor was outta whack. After a top engine clean & other junk the problem went away for good
