Intermittent failures may cause CHECK ENGINE light to flicker or stay on until the intermittent fault goes away. However, the corresponding fault will be retained in PCM memory. 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.
