Intermittent Simulation

WARNING: This page is about a different car, the 2002 Pontiac Grand Am, 2002 Oldsmobile Alero, 2001 Pontiac Grand Am, and 2001 Oldsmobile Alero. However, it is still accessible from the selected car via links, so may be relevant.

Use the following methods to reproduce conditions causing intermittent problem(s):

Apply light vibration to components.
Apply small amount of heat to component.
Wiggle or bend wiring harness.
Remove/apply vacuum supply source.

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