Fail-Safe Table

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.
P0030 HO2S heater control circuit (Sensor-1)
P0031 HO2S heater control circuit low (Sensor-1)
P0032 HO2S heater control circuit high (Sensor-1)
P0102 Mass air flow circuit low input
P0103 Mass air flow circuit high input
P0112 Intake air temperature sensor circuit low
P0113 Intake air temperature sensor circuit high
P0117 Engine coolant temperature circuit low
P0118 Engine coolant temperature circuit high
P0122 Throttle position sensor (main) circuit low

Refer to "DTC Table in Section 5A".
Fail-safe operation
ECM stops air/fuel ratio control.
• ECM controls injector drive time (fuel injection
volume) according to throttle valve opening
(closed throttle position or not).
• ECM stops EGR control.
ECM controls actuators assuming that intake air
temperature is 20 °C (68 °F).
• ECM controls actuators assuming that engine
coolant temperature is 80 °C (176 °F).
• ECM operates radiator cooling fan.
• ECM turns off throttle actuator control relay and
throttle valve is fixed at the opening of about 7°
from its completely closed position (default
opening).
• ECM controls fuel cut at specified engine speed.
• ECM stops air/fuel ratio control.
