Test Procedures

WARNING: This page is about a different car, the 2000 Ford Pickup, 2000 Ford F550 Super Duty, 2000 Ford F450 Super Duty, 2000 Ford Contour, and 2000 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

Intermittent fault testing requires duplicating circuit or component failure to identify the problem. These procedures may lead to the PCM setting a fault code, which may help in diagnosis. To reproduce 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. Use test results to identify a faulty component or circuit. If fault code is not present, check for intermittents. See TEST Z under SYSTEM TESTS in SELF-DIAGNOSTICS - EEC-V (GASOLINE) article.
