Remarks

Reference page

Malfunction 
indicator 
lamp circuit

Engine speed will not rise 
more than 2,500 rpm due 
to the fuel cut

When there is an open circuit on MIL circuit, the ECM cannot warn the 
driver by lighting up MIL when there is malfunction on engine control 
system.
Therefore, when electrical controlled throttle and part of ECM related 
diagnoses are continuously detected as NG for 5 trips, ECM warns the 
driver that engine control system malfunctions and MIL circuit is open 
by means of operating fail safe function.
The fail safe function also operates when above diagnoses except MIL 
circuit are detected and demands the driver to repair the malfunction.

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.

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

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.

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.

Engine oil temperature sensor

Exhaust valve timing control does not function.

Vehicle speed sensor

The cooling fan operates (Highest) while engine is running.

DTC Inspection Priority Chart

INFOID:0000000009022474

If some DTCs are displayed at the same time, perform inspections one by one based on the following priority

chart.

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.

P2119

Electric throttle control actuator

(When electric throttle control actuator does not function properly due to the return spring 
malfunction:)
ECM controls the electric throttle actuator by regulating the throttle opening around the 
idle position. The engine speed will not rise more than 2,000 rpm.

(When throttle valve opening angle in fail safe mode is not in specified range:)
ECM controls the electric throttle control actuator by regulating the throttle opening to 20 
degrees or less.

(When ECM detects the throttle valve is stuck open:)
While the vehicle is driving, it slows down gradually by fuel cut. After the vehicle stops, the 
engine stalls.
The engine can restart in the Neutral position, and engine speed will not exceed 1,000 rpm 
or more.

Accelerator pedal position sen-
sor

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.
