Intermittent Simulation

WARNING: This page is about a different car, the 1998 Pontiac Trans Sport, 1998 Oldsmobile Silhouette, and 1998 Chevrolet Venture. However, it is still accessible from the selected car via links, so may be relevant.

Use following methods to reproduce conditions causing intermittent.

Apply light vibration to components.
Heat component.
Wiggle or bend wiring harness.
Spray component with water.
Remove/apply vacuum supply source.

Monitor circuit/component voltage or resistance while attempting to simulate intermittent. If vehicle is running, monitor for trouble codes. Use test results to identify faulty component or circuit.
