Intermittent Failures

Intermittent failures may cause malfunction light to flicker or illuminate and go out after the intermittent fault goes away. The corresponding trouble code, however, will be stored 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.
