for Preparation Click here


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
P0037
P0038
P102D
Heated oxygen sensor heater
ECM turns off heated oxygen sensor heater
Power switch off
P0102
P0103
Mass air flow meter sub-assembly
ECM calculates ignition timing according to engine speed and throttle valve position
Pass condition detected
P0107
P0108
Manifold absolute pressure sensor
ECM turns off EGR valve operate
Pass condition detected
P0112
P0113
Intake air temperature sensor
ECM estimates intake air temperature to be 20°C (68°F)
Pass condition detected
P0115
P0117

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
EGR valve assembly
ECM assumes that EGR valve is closed, so that ignition timing controlled to a safe value
Pass condition detected
P0403
EGR valve assembly
ECM assumes that EGR valve is closed, so that ignition timing controlled to a safe value
Pass condition detected
P261B
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.
