Description

ECS009B0

Accelerator pedal position (APP) sensor (Throttle position sensor)
Electric throttle control actuator consists of throttle control motor,
acceleration pedal position sensor, throttle position sensor, etc. The
actuator sends a signal to the TCM.

SELF-DIAGNOSIS CODE CONFIRMATION PROCEDURE

After the repair, perform the following procedure to confirm the malfunction is eliminated.

With CONSULT-II

1.

Start engine.

2.

Select “SELF-DIAG RESULTS” mode for A/T with CONSULT-II.

3.

Drive vehicle under the following conditions:
Selector lever in “D” position, vehicle speed higher than 10 km/h
(6 MPH), throttle opening greater than 1/2 of the full throttle
position and driving for more than 3 seconds.

4.

If DTC is detected, go to

AT-359, "Diagnostic Procedure"

.

Without CONSULT-II

1.

Start engine.

2.

Drive vehicle under the following conditions:
Selector lever in “D” position, vehicle speed higher than 10 km/h
(6 MPH), throttle opening greater than 1/2 of the full throttle
position and driving for more than 3 seconds.

3.

Perform self-diagnosis.
Refer to

AT-252, "Diagnostic Procedure Without CONSULT-II"

Diagnostic Procedure

ECS009B2

1.

CHECK DTC WITH ECM

●

Check DTC with CONSULT-II “ENGINE”.

Turn ignition switch ON and select “SELF DIAGNOSTIC RESULTS” mode for “ENGINE” with CONSULT-II.
Refer to

EC-55, "Emission-related Diagnostic Information"

(EURO OBD) or

EC-581, "Emission-related Diag-

nostic Information"

(Except EURO OBD).

OK or NG

OK (With CONSULT-II)>>GO TO 2
OK (Without CONSULT-II)>>GO TO 3
NG

>> Perform trouble diagnosis for the DTC for engine control.

2.

CHECK INPUT SIGNAL (WITH CONSULT-II)

With CONSULT-II

1.

Turn ignition switch to “ON” position.
(Do not start engine.)

2.

Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for
“A/T” with CONSULT-II.

3.

Read out the value of “THRTL POS SEN”.

OK or NG

OK

>> GO TO 4

NG

>> Check harness for short or open between ECM and TCM regarding throttle position sensor circuit.
