DTC Description

INFOID:0000000010703053

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connector (TP sensor 1 or 2 circuit is open or shorted.)
• Electric throttle control actuator (TP sensor 1 or 2)

FAIL-SAFE

DTC CONFIRMATION PROCEDURE

1.

CHECK DTC PRIORITY

If DTC P2135 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-364, "Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to 

GI-41, "Intermittent Incident"

.

NO-2

>> Confirmation after repair: INSPECTION END

Diagnosis Procedure

INFOID:0000000010703054

1.

CHECK DTC PRIORITY

DTC No.

CONSULT screen terms

DTC detecting condition

P2135

TP SENSOR-B1
(Throttle/pedal position sensor/switch “A”/ 
“B” voltage correlation)

Rationally incorrect voltage is sent to ECM compared with the signals from 
TP sensor 1 and TP 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 con-

dition. So, the acceleration will be poor. 

NOTE:
If throttle position sensor1 and 2 malfunction at the same time conducts following control.
• ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed 

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