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.
ECM deactivates ASCD operation.

P0607

ECM

VVEL actuator motor relay is turned off, and VVEL value is become at a minimum angle.
Engine speed will not rise more than 3,500 rpm due to the fuel cut.

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.

P1088

VVEL control function

VVEL of normal bank is controlled at VVEL angle of abnormal bank.
Engine speed will not rise more than 3,500 rpm due to the fuel cut.

P1092

VVEL control shaft position 
sensor

VVEL value is maintained at a fixed angle.
Engine speed will not rise more than 3,500 rpm due to the fuel cut

P1608

VVEL control shaft position 
sensor

VVEL actuator motor relay is turned off, and VVEL value is become at a minimum angle.
Engine speed will not rise more than 3,500 rpm due to the fuel cut.

P1090
P1093

VVEL actuator motor

VVEL of normal bank is controlled at VVEL angle of abnormal bank.
Engine speed will not rise more than 3,500 rpm due to the fuel cut.

VVEL actuator motor relay is turned off, and VVEL value is become at a minimum angle.
Engine speed will not rise more than 3,500 rpm due to the fuel cut.

P1091

VVEL actuator motor relay

VVEL actuator motor relay is turned off, and VVEL value is become at a minimum angle.
Engine speed will not rise more than 3,500 rpm due to the fuel cut.

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.

P1236

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.

P1238

P2119

Electric throttle control ac-
tuator

(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 because of regulating the throttle open-
ing to 20 degrees or less.

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

P1290
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.

P1606

VVEL control module

VVEL actuator motor relay is turned off, and VVEL value is become at a minimum angle.
Engine speed will not rise more than 3,500 rpm due to the fuel cut.

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

P2122
P2123
P2127

P2138

Accelerator pedal 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.
Therefore, the acceleration will be poor. 

DTC No.
