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 (symptom)
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).
•
ECM stops EGR control.
P0103
Mass air flow circuit high input
P0112
Intake air temperature sensor circuit low
ECM controls actuators assuming that intake air temperature is 20 °C (68 °F).
P0113
Intake air temperature sensor circuit high
P0117
