Intermittent Failures

Intermittent failures may cause MIL to flicker or glow and go out after intermittent fault goes away. Corresponding trouble code will be retained in ECM memory (except for Codes 16, 43, 51 and 53). Codes must be erased from memory after repair has been made. Intermittent failures may be caused by sensor, connector or wiring related problems. Refer to INTERMITTENTS text accompanying each test (as applicable).

If no faults were found while performing BASIC DIAGNOSTIC PROCEDURES, proceed with self-diagnostics. If no fault codes are present after entering self-diagnostics, proceed to appropriate TESTS W/O CODES article.
