Intermittent Simulation

WARNING: This page is about a different car, the 1994 Toyota 4Runner. However, it is still accessible from the selected car via links, so may be relevant.

To reproduce the conditions creating an intermittent fault, use the following methods:

Lightly vibrate component. See VIBRATION METHOD .
Heat component. See HEAT METHOD .
Wiggle or bend wiring harness. See VIBRATION METHOD .
Spray component with water. See HUMIDITY METHOD .
Remove/apply vacuum source.

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