Intermittent Failures
Intermittent failures may cause CHECK ENGINE light to flicker or stay on until the intermittent fault goes away. However, the corresponding trouble code will be retained in SBEC-II memory. If related fault does not reoccur within a certain time frame, related trouble code will be erased from SBEC-II memory. Intermittent failures can be caused by faulty sensor, bad connector or wiring related problems. See INTERMITTENTS in TESTS W/O CODES article.
