ECM
*1: Accelerator pedal position sensor 2 signal and throttle position sensor 2 signal are converted by ECM internally. Thus, they differ
from ECM terminals voltage signal.
*2: Before measuring the terminal voltage, confirm that the battery is fully charged. Refer to
PG-91, "How to Handle Battery"

NOTE:
• ECM is located in the engine room left side near battery.
• Connect a break-out box (EG17550000) and harness adapter (EG17550400) between the ECM and ECM
harness connector.
- Use extreme care not to 2 pins at one time.
- Data is for comparison and may not be exact.
• Specification data are reference values and are measured between each terminal and ground.
• Pulse signal is measured by CONSULT.

Malfunction
indicator
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.

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

DTC Inspection Priority Chart
INFOID:0000000009753120
If some DTCs are displayed at the same time, perform inspections one by one based on the following priority
chart.
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
P1197
Out of gas
Engine torque is limited.
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 throttle 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 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 the Neutral position, and engine speed will not exceed 1,000 rpm
or more.

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
