Intermittent Failures
WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, 1994 Chrysler New Yorker, 1994 Chrysler LHS, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
Intermittent failures may cause MIL to flicker or stay on until the intermittent failure goes away. However, the corresponding trouble code will be retained in PCM memory. If failure does not reoccur within a certain time frame (before 50 ignition on/off cycles), corresponding trouble code will be erased from PCM memory.
Intermittent failures can be caused by faulty sensor, bad connection, or wiring related problems. Refer to INTERMITTENTS heading in the TESTS W/O CODES article in the ENGINE PERFORMANCE Section.
