Intermittent Simulation

To reproduce the conditions creating an 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 self-diagnostic codes. See TESTS W/CODES - EEC-IV (4.6L) article in the ENGINE PERFORMANCE section. Use test results to identify a faulty component or circuit.

NOTE: For test equipment connection and CONTINUOUS MONITOR MODE test operation, see TESTS W/CODES - EEC-IV (4.6L) article in the ENGINE PERFORMANCE section.
