DTC RELATED ITEM
DTC No.
Detected items
Engine operating condition in fail safe mode
P0011
Intake valve timing control
The signal is not energized to the intake valve timing control solenoid valve and the valve
control does not function.
P0014
Exhaust valve timing control
The signal is not energized to the exhaust valve timing control solenoid valve and the valve
control does not function.
P0101
P0102
P0103
Mass air flow sensor circuit
Engine speed will not rise more than 2,400 rpm due to the fuel cut.
P0117
P0118
Engine coolant temperature
sensor circuit
Engine coolant temperature will be determined by ECM based on the following conditions.
CONSULT displays the engine coolant temperature decided by ECM.
Condition
Engine coolant temperature decided
(CONSULT display)
Just as ignition switch is turned ON or START
40
°C (104°F)
Approx. 4 minutes or more after engine starting
80
°C (176°F)
Except as shown above
40 - 80
°C (104 - 176°F)
(Depends on the time)
When the fail safe system for engine coolant temperature sensor is activated, the cooling
fan operates while engine is running.

P2135
Throttle position sensor
The ECM controls the electric throttle control actuator in regulating the throttle opening in
order for the idle position to be within +10 degrees.
The ECM regulates the opening speed of the throttle valve to be slower than the normal
condition.
So, the acceleration will be poor.
P0196
P0197
P0198
Engine oil temperature sensor
Exhaust valve timing control does not function.
P0500
Vehicle speed sensor
The cooling fan operates (Highest) while engine is running.
P0524
Engine oil pressure
• ECM illuminates oil pressure warning lamp on the combination meter.
• Engine speed will not rise more than 4,000 rpm due to the fuel cut.
• Fail-safe is canceled when ignition switch OFF
→ ON.
P0605
ECM
(When ECM calculation function is malfunctioning:)
ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P0643
Sensor power supply
ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P1805
Brake switch
ECM controls the electric throttle control actuator by regulating the throttle opening to a
small range.
Therefore, acceleration will be poor.
Vehicle condition
Driving condition
When engine is idling
Normal
When accelerating
Poor acceleration
P2100
P2103
Throttle control motor relay
ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P2101
Electric throttle control function
ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P2118
Throttle control motor
ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
