Engine General Information and Diagnosis: 1A-36
Fail-Safe Table
S5JB0A1104006
When any of the following DTCs is detected, ECM enters fail-safe mode as long as malfunction continues to exist but
that mode is canceled when ECM detects normal condition after that.
DTC No. Detected item Fail-safe operation
) P0030 HO2S heater control circuit (Sensor-1)
ECM stops air/fuel ratio control.) P0031 HO2S heater control circuit low (Sensor-1)
) P0032 HO2S heater control circuit high (Sensor-1)
) P0102 Mass air flow circuit low input • ECM controls injector drive time (fuel injection
volume) according to throttle valve opening
(closed throttle position or not).
