Fail-Safe Chart

If any of the following DTCs are set, the ECM enters fail-safe mode to allow the vehicle to be driven temporarily.

DTC	Component	Fail-Safe Operation	Fail-Safe Deactivation Condition
P0011, P0015, P0021 and P0025	VVT system	Idle up (control of combustion worsening) Stopping fuel cut control	Pass condition detected
P0031, P0032, P0051, P0052, P101D and P103D	Air fuel ratio sensor heater	ECM turns off air fuel ratio sensor heater	Ignition switch off
P0037, P0038, P0057, P0058, P102D and P105D	Heated oxygen sensor heater	ECM turns off heated oxygen sensor heater	Ignition switch off
P0102 and P0103	Mass air flow meter sub-assembly	ECM calculates ignition timing according to engine speed and throttle valve position	Pass condition detected
P0112 and P0113	Intake air temperature sensor	ECM estimates intake air temperature sensor to be 20°C (68°F)	Pass condition detected
P0115, P0117 and P0118	Engine coolant temperature sensor	ECM estimates engine coolant temperature sensor to be 80°C (176°F)	Pass condition detected
P0120, P0121, P0122, P0123, P0220, P0222, P0223, P0604, P0606, P060A, P060B, P060D, P060E, P0657, P2102, P2103, P2111, P2112, P2118, P2119 and P2135	Electronic throttle control system	The ECM cuts off throttle actuator current and the throttle valve returns to 6° throttle position by return spring The ECM then adjusts engine output by controlling fuel injection (intermittent fuel cut) and ignition timing in accordance with accelerator pedal opening angle to allow vehicle to continue at minimal speed*1	Pass condition detected and then ignition switch turned off
P0300, P0301, P0302, P0303, P0304, P0305 and P0306*2	Fuel injector assembly Electronic throttle control system	When a catalyst-damaging misfire occurs (MIL blinking), the following fail-safe operation is performed for catalyst overheat malfunction prevention. Under a low load and at a low engine speed: - Fuel cut is performed on the malfunctioning cylinder. Under a high load and at a high engine speed: - Throttle valve opening angle control is performed. - Fuel cut is performed on all cylinders or the malfunctioning cylinder.	Pass condition detected and then ignition switch turned off
P0327, P0328, P0332 and P0333	Knock control sensor	The ECM sets ignition timing to maximum retard	Ignition switch off
P0351, P0352, P0353, P0354, P0355 and P0356	Ignition coil assembly	The ECM cuts fuel	Pass condition detected
P2120, P2121, P2122, P2123, P2125, P2127, P2128 and P2138	Accelerator pedal sensor assembly	Accelerator pedal sensor assembly has 2 sensor circuits: Main and Sub If either circuit malfunctions, the ECM controls engine using the other circuit If both circuits malfunction, the ECM regards the accelerator pedal as being released. As a result, the throttle valve is closed and the engine idles	Pass condition detected and then ignition switch turned off

HINT:

*1: The vehicle can be driven slowly when the accelerator pedal is depressed slowly. If the accelerator pedal is depressed quickly, the vehicle may speed up and slow down erratically.
*2: Misfire related fail-safe operations occur when catalyst overheat malfunctions occur.
