Intermittent Failures

Intermittent failures may cause malfunction light to flicker on and off after intermittent fault goes away. Corresponding trouble code will be retained in ECU memory.

If related fault does not reoccur within a certain time frame, related trouble code will be erased from ECU memory. Intermittent failures may be caused by sensor, connector or wiring related problems. See INTERMITTENTS in TESTS W/O CODES article in the ENGINE PERFORMANCE Section.
