DTC RELATED ITEM
Detected itemsEngine operating condition in
fail-safe mode Remarks
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.
DTC No. Detected items
Engine operating condition in fail-safe mode
P0011 Intake valve timing control The signal is not energized to the intake valve timing control solenoid valve and the valve control does not function.
P0102
P0103 Mass air flow sensor circuit Engine speed will not rise more than 2,400 rpm due to the fuel cut.
P0117
P0118 Engine coolant tempera-
ture sensor circuit Engine coolant temperature will be determined by ECM based on the following condition.
CONSULT-III displays the engine coolant temperature decided by ECM.

P2135 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.
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.
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.
P1805 Brake switch ECM controls the electric throttle control actuator by regulating the throttle opening to a
small range.
Therefore, acceleration will be poor.

DTC Inspection Priority ChartINFOID:0000000005930153
If some DTCs are displayed at the same time, perform inspections one by one based on the following priority
chart.
P2119 Electric thro
ttle 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 N or P (A/T), Neutral (M/T) position, and engine speed will not
exceed 1,000 rpm or more.
P2122
P2123
P2127
P2128
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.
So, the acceleration will be poor.
