Intermittent Failures
Intermittent failures may cause MIL to flicker or glow and go out after intermittent trouble code goes away. However, corresponding trouble code will be retained in PCM memory. If related trouble code does not reoccur within a certain time frame, related trouble code will be erased from PCM memory. Intermittent failures may be caused by a sensor, connector or wiring problems. See INTERMITTENTS in TESTS W/O CODES - 2.4L article.
