Intermittent Failures

Intermittent failures may cause Malfunction Indicator Light (MIL) to flicker or glow and go out after intermittent fault goes away. However, corresponding trouble code will be stored in ECM memory. Not all trouble codes will illuminate MIL. If related fault does not reoccur within a certain time frame, related trouble code will be erased from ECM memory. Intermittent failures may be caused by sensor, connector or wiring related problems. See INTERMITTENTS in TESTS W/O CODES article.

NOTE: Follow proper diagnostic routine when diagnosing system. See DIAGNOSTIC ROUTINE table.
