Intermittent Failures

Intermittent failures may cause CHECK ENGINE light to flicker or glow and go out after intermittent fault goes away. Corresponding trouble code will be retained in ECU memory (except for Codes 16, 17, 18, 43, 51 and 53). Codes 16, 17, 18, 43, 51 and 53 do not illuminate CHECK ENGINE light and are output only during test procedures. See appropriate diagnostic code chart.

Codes must be erased from memory after repair has been made. Intermittent failures may be caused by sensor, connector or wiring related problems. See INTERMITTENTS in TESTS W/O CODES article in the ENGINE PERFORMANCE Section.
