Continuous Memory Codes (Soft Faults)

These codes indicate a fault that may or may not be present at time of testing. These codes are used to diagnose intermittent problems. Continuous Memory Codes are retrieved after KOEO SELF-TEST. Some codes may turn on MIL/CHECK ENGINE light. Corresponding soft fault code will be retained in PCM memory. If fault does not re-occur within 40 warm-up cycles (80 cycles on some models), PCM will automatically clear code or technician may clear service codes from memory. See CLEARING CODES. Intermittent faults may be caused by a sensor, connector or wiring-related problem. See INTERMITTENTS in TESTS W/O CODES article in the ENGINE PERFORMANCE section.

CAUTION: Continuous Memory Codes should be recorded when retrieved. These codes may be used to identify intermittent problems occurring after all KOEO and KOER codes have been repaired and a Code 111 (pass code) has been obtained. Some Continuous Memory Code faults may not be valid after KOEO and KOER codes are serviced.
