Intermittent Simulation

WARNING: This page is about a different car, the 1994 Mercury Grand Marquis, 1994 Lincoln Town Car, 1994 Lincoln Mark VIII, and 1994 Ford Crown Victoria. 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.
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.
