Intermittent Faults

Intermittent faults may cause CHECK ENGINE light to flicker or illuminate and go out after the intermittent fault goes away. However, the corresponding trouble code will be retained in ECU memory. If related fault does not reoccur within a certain time frame, related trouble will be erased from ECU memory. Intermittent failures may be caused by a sensor, connector, or wiring related problem. See INTERMITTENTS in appropriate G -TESTS W/O CODES article.
