Intermittent Simulation

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

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

Monitor circuit/component voltage or resistance while attempting to simulate intermittent. If engine is running, monitor for self-diagnostic codes. See the TESTS W/CODES - EEC (2.5L) article. Use the results to identify a faulty component or circuit.
