• Engine idling stop is inhibited.
• Cooling fan operates while engine is running.
• Engine coolant temperature will be determined by ECM based on the following condi-

Throttle position sensor

• Engine idling stop is inhibited.
• 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.

Vehicle speed sensor

When the fail-safe system for vehicle speed sensor is activated, the cooling fan operates 
(Highest) while engine is running.

P0605

ECM

ECM enters various fail-safe mode according to the detected malfunction.
• Engine idling stop is inhibited.
• The engine speed will not rise 2,500 rpm or more.
• 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.

P0643

Sensor power supply

• Engine idling stop is inhibited.
• ECM stops the electric throttle control actuator control, throttle valve is maintained at a 

fixed opening (approx. 5 degrees) by the return spring.

P1195

Engine does not start

• ECM stops the engine according to the fuel cut request signal sent from HV ECU.
• The vehicle drives using the motor.

DTC Inspection Priority Chart

INFOID:0000000004211661

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

chart.

P1196

Poor engine power

• ECM stops the engine according to the fuel cut request signal sent from HV ECU.
• The vehicle drives using the motor.

P1197

Fuel run out

• ECM stops the engine according to the fuel cut request signal sent from HV ECU.
• The vehicle drives using the motor.

P1805

Brake switch

ECM controls the electric throttle control actuator by regulating the throttle opening to a 
small range.
Therefore, acceleration will be poor.

P2100
P2103

Throttle control motor relay • Engine idling stop is inhibited.

• 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

• Engine idling stop is inhibited.
• 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

• Engine idling stop is inhibited.
• 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 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 by regulating the throttle opening to 20 
degrees or less.

(When ECM detects the throttle valve is stuck open:)
• Engine idling stop is inhibited.
• The engine speed will not rise 1,150 rpm or more.

DTC No.
