Intermittent Simulation

WARNING: This page is about a different car, the 1998 Pontiac Grand Prix, 1998 Oldsmobile Intrigue, 1998 Chevrolet Monte Carlo, 1998 Chevrolet Lumina, and 1998 Buick Regal. However, it is still accessible from the selected car via links, so may be relevant.

To reproduce the conditions causing intermittent fault, use the following methods:

Lightly vibrate component.
Heat component.
Wiggle or bend wiring harness.
Spray component with water.
Remove/apply vacuum source.

Monitor circuit/component voltage or resistance while simulating intermittent. If engine is running, monitor for diagnostic trouble codes. Use test results to identify a faulty component or circuit.
