DTC DETECTION LOGIC

NOTE:

If DTC P2127 or P2128 is displayed with DTC P31E5, first perform the trouble diagnosis for DTC P31E5.

Refer to 

EVC-351, "DTC Logic"

.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

• Turn power switch OFF and wait at least 90 seconds.

CAUTION:

During this period, never perform vehicle handling such as opening and closing of doors. If some

kind of vehicle handling is performed, then wait another 90 seconds or more from the time of the

vehicle handling.

• Make sure that 12V battery voltage is 11 V or more.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

1. Turn power switch ON and wait at least 1 second.

2. Check self-diagnostic result.
Is DTC detected?

YES

>> Proceed to 

EVC-214, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000010120668

CHECK APP SENSOR 2 POWER SUPPLY-1

1. Turn power switch OFF.

2. Disconnect accelerator pedal position (APP) sensor harness connector.

3. Turn power switch ON.

4. Check the voltage between APP sensor harness connector terminals.

Is the inspection result normal?

YES

>> GO TO 6.

NO

>> GO TO 2.

2.

CHECK APP SENSOR 2 POWER SUPPLY-2

Check the voltage between APP sensor harness connector and ground.

DTC detecting condition

Possible cause

P2127

APP SENSOR E
(Throttle/Pedal position sen-
sor/switch “E” circuit low)

An excessively low voltage from the APP sensor 2 is 
sent to VCM.

• Harness or connectors

(Accelerator pedal position sen-
sor 2 circuit is shorted.)

• Accelerator pedal position sen-

sor 2

P2128

APP SENSOR E
(Throttle/Pedal position sen-
sor/switch “E” circuit high)

An excessively high voltage from the APP sensor 2 is 
sent to VCM.
