Intermittent Failures

Intermittent failures may cause MIL to flicker or stay on until intermittent fault goes away. However, PCM memory will retain corresponding fault. If related fault does not reoccur within a certain time frame, related fault will be erased from PCM memory. Intermittent failures can be caused by a faulty sensor, bad connector or wiring related problems.
