Intermittent Faults

Intermittent faults may cause Malfunction Indicator Light (MIL) to flicker or illuminate and go out after the intermittent fault goes away. However, the corresponding Diagnostic Trouble Code (DTC) will be retained in PCM memory. If related malfunction does not reoccur within a certain time frame, related DTC will be erased from PCM memory. Intermittent faults may be caused by sensor, connector or wiring problems. See INTERMITTENTS in TROUBLE SHOOTING - NO CODES - VILLAGER article.
