Checking Resistance On Knock Sensors

[SteveTheTech]

I had a car in this morning with a P0325 (knock sensor), this example is a 97 I30 sine they are the easiest to show.

1:After confirming the code is present, get your multimeter and zero it out if you have the capability.



2:Disconnect the sensor

3:Connect you leads and view your reasults



In this example the sensor is open and requires replacement

Specs:

For this model the spec is 500-620 K Ohms at 75 degree F.
