The Wiggle Test


A wiggle test can be used to locate the cause of some intermittent faults. The sensor, switch or the PCM wiring can be back-probed, as shown, while the test is done.

During testing, move or wiggle the suspect device, connector or wiring while watching for a change. If the DVOM has a Min/Max record mode, use this mode during the test.
