Testing a Knock Sensor

btwilson86 · 01-17-2009, 07:23 AM

Hi, I have an 87 NA and an 88 NA, both of which have the Knock Sensor Engine Code. On both cars the wiring is still intact, meaning from plug to ECU pin I have continuity. So I am wondering if anyone knows how to bench test a Knock Sensor to see if it's faulty.

Any ideas or links would be appreciated.
