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 or stops fuel injection.
 
DTC Component Fail-safe Operation Fail-safe Deactivation Condition
P0031
P0032
P101D
Air fuel ratio sensor heater ECM turns off air fuel ratio sensor heater Power switch off

Electronic throttle control system ECM cuts off throttle actuator current and throttle valve returns to the 5.5° throttle position by return spring
The ECM stops the engine and the vehicle can be driven using solely the hybrid system
*1
Pass condition detected and then power switch turned off
P0327
P0328
Knock control sensor ECM sets ignition timing to maximum retard Power switch off
P0351 to P0354 Ignition coil assembly
(Igniter)
ECM cuts fuel Pass condition detected
P0401
P0403
EGR valve assembly ECM assumes that EGR valve is closed, so that ignition timing controlled to a safe value Pass condition detected
P216B Engine water pump assembly Output duty ratio of the WPO terminal repeats a cycle of 0% for 30 seconds and then 85% for 5 seconds*2 Power switch off
P261C Engine water pump assembly Output duty ratio of the WPO terminal remains at 0%*2 Power switch off
P261D Engine water pump assembly Output duty ratio of the WPO terminal remains at 0%*2 Power switch off

 

HINT:
 
  1. *1: The vehicle can be driven slowly when the accelerator pedal is depressed firmly and slowly.
  2. *2: When the coolant temperature reaches 105°C (221°F), the engine is stopped and the hybrid system is solely used to driving vehicle.
  3.
