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

Malfunction indicator 
lamp circuit

When there is an open circuit on MI circuit, the ECM cannot warn the 
driver by lighting up MI 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 MI circuit is open by 
means of operating fail-safe function.
The fail-safe function also operates when above diagnoses except MI 
circuit are detected and demands the driver to repair the malfunction.

Engine coolant tempera-
ture sensor circuit

Engine coolant temperature will be determined by ECM based on the time after turning 
ignition switch ON or START.
CONSULT-III displays the engine coolant temperature decided by ECM.

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. 

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.
ECM deactivates ASCD operation.

P1121

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:)
While the vehicle is driving, it slows down gradually by fuel cut. After the vehicle stops, the 
engine stalls.
The engine can restart in P or N (A/T), Neutral (M/T) position, and engine speed will not 
exceed 1,000 rpm or more.

P1122

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.

P1124
P1126

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.

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.
