Reference Value INFOID:0000000004780383
VALUES ON THE DIAGNOSIS TOOL Remarks:
• Specification data are reference values.
• Specification data are output/input values which are detected or supplied by the ECM at the connector.
*Specification data may not be directly relat ed to their components signals/values/operations.
I.e. Adjust ignition timing with a timing light before m onitoring IGN TIMING, because the monitor may show the
specification data in spite of the ignition timing not bei ng adjusted to the specification data. this IGN TIMING
monitors the data calculated by the ECM according to the signals input from the camshaft position sensor and
other ignition timing related sensors.
Monitor Item Condition Values/Status
ENG SPEED • Run engine and compare CONSULT-III value with the tachometer indication. Almost the same speed as
the tachometer indication.

*: 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.
TERMINAL LAYOUT
PHYSICAL VALUES NOTE:
• ECM is located in the engine room left side near battery.
• Specification data are reference values and are measured between each terminal and ground.
• Pulse signal is measured by CONSULT-III.
CAUTION:
Do not use ECM ground terminals wh en measuring input/output voltage. Doing so may result in dam-
age to the ECMs transistor. Use a ground ot her than ECM terminals, such as the ground.

DTC RELATED ITEM
Detected items
Engine 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.
Condition Engine coolant temperature decided
(CONSULT-III display)
Just as ignition switch is turned ON
or START 40
°C (104 °F)
More than approx. 4 minutes after
engine starting 80
°C (176 °F)
Except as shown above 40 - 80
°C (104 - 176 °F)
(Depends on the time)
When the fail-safe system for engine coolant temperature sensor is activated, the cooling
fan operates while engine is running.

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.
Vehicle condition Driving condition
When engine is idling Normal
When accelerating Poor acceleration
