Fail-Safe Chart [09/2017 - ]

If any of the following DTCs are stored, the ECM enters fail-safe mode to allow the vehicle to be driven temporarily or stops fuel injection.

DTC Code	Component	Fail-Safe Operation	Fail-Safe Deactivation Condition
P0031 P0032 P101D	Air fuel ratio sensor heater	The ECM turns off the air fuel ratio sensor heater.	Power switch off
P0037 P0038 P102D	Heated oxygen sensor heater	The ECM turns off the heated oxygen sensor heater.	Power switch off
P0102 P0103	Mass air flow meter sub-assembly	The ECM calculates ignition timing according to the engine speed and throttle valve position.	Pass condition detected
P0106 P0107 P0108	Manifold absolute pressure sensor	The ECM turns off EGR valve operate.	Pass condition detected
P0112 P0113	Intake air temperature sensor	The ECM estimates the intake air temperature to be 20°C (68°F).	Pass condition detected
P0115 P0117 P0118	Engine coolant temperature sensor	The ECM estimates the engine coolant temperature to be 80°C (176°F).	Pass condition detected
P0120 P0121 P0122 P0123 P0220 P0222 P0223 P0604 P0606 P060A P060B P060E P0657 P2102 P2103 P2111 P2112 P2118 P2119 P2135	Electronic throttle control system	The ECM cuts off throttle actuator current and the throttle valve is returned to a 5.5° throttle position by the return spring. The ECM stops the engine and the vehicle can be driven using solely the hybrid system.*	Pass condition detected and then power switch turned off
P0327 P0328	Knock control sensor	The ECM sets the ignition timing to maximum retard.	Power switch off
P0351 P0352 P0353 P0354	Ignition coil assembly	The ECM cuts the fuel injection.	Pass condition detected
P0401 P0403	EGR valve assembly	ECM assumes that EGR valve assembly is closed, so that ignition timing controlled to a safe valve.	Pass condition detected and then power switch turned off
P2237 P2238 P2239 P2252 P2253	Air fuel ratio sensor	Air fuel ratio feedback control is stopped. Current to the air fuel ratio sensor heater is cut.	Pass condition detected and then power switch turned off

HINT:

*: The vehicle can be driven slowly when the accelerator pedal is depressed firmly and slowly.
