DTC Description

INFOID:0000000010703056

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connector
- APP sensor 1 or 2 circuit is open or shorted.
- Sensor power supply 2 circuit is shorted.
• Accelerator pedal position sensor (APP sensor 1 or 2)
• Sensor power supply 2 circuit

FAIL-SAFE

DTC CONFIRMATION PROCEDURE

1.

CHECK DTC PRIORITY

If DTC P2138 is displayed with DTC P0643, first perform the trouble diagnosis for DTC P0643.

Is applicable DTC detected?

YES

>> Perform diagnosis of applicable. Refer to 

ECM-306, "DTC Description"

.

NO

>> GO TO 2.

2.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
1.

Turn ignition switch OFF and wait at least 10 seconds.

2.

Turn ignition switch ON.

3.

Turn ignition switch OFF and wait at least 10 seconds.

TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 8 V at idle.

>> GO TO 3.

3.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Start engine and let it idle for 1 second.

2.

Check DTC.

Is DTC detected?

YES

>> Proceed to 

ECM-368, "Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to 

GI-41, "Intermittent Incident"

.

NO-2

>> Confirmation after repair: INSPECTION END

DTC No.

CONSULT screen terms

(Trouble diagnosis content)

DTC detecting condition

P2138

APP SENSOR
(Throttle/pedal position sensor/switch “D”/
“E” voltage correlation)

Rationally incorrect voltage is sent to ECM compared with the signals from 
APP sensor 1 and APP sensor 2.

Engine operating condition in fail-safe mode

Fail safe mode

Vehicle behavior

Others

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. 
Therefore, the acceleration will be poor. 
NOTE:
If accelerator pedal position sensor 1 and 2 malfunction at the same time conducts following con-
trol.
• ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed 

opening (approx. 5 degrees) by the return spring.
