If some DTCs are displayed at the same time, perform inspections one by one based on the following priority
chart.
P060A
ECM NOTE:
Fail-safe may not occur depending on malfunction type.
• ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (Approx. 5 decrees) by the return spring.
• The position of the following commponents is fixed.
- Intake valve timing control solenoid valve
- Exhaust valve timing control solenoid valve
• Engine torque may be limited.
• ASCD operation may be deactivated.
P0643
ECM • ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (Approx. 5 decrees) by the return spring.
• The position of the following commponents is fixed.
- Intake valve timing control solenoid valve
- Exhaust valve timing control solenoid valve
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.
P1720 Vehicle speed sensor ECM operates active grille shutter to fully-open position.
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 thro ttle 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 sp ring
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.

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.
