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.

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.

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.
