id0102d2812100

DTC P2135

TP sensor No.1/No.2 voltage correlation

DETECTION CONDITION
•  The PCM flagged a concern indicating that TP sensor No.1 and TP sensor No.2 disagree by more than a calibrated limit.
POSSIBLE CAUSE
•  Short to power supply between TP sensor No.1 terminal F and PCM terminal 2Z
•  Short to power supply between TP sensor No.2 terminal C and PCM terminal 2AD
•  TP sensor circuits are shorted each other
•  TP sensor malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
•  Has FREEZE FRAME DATA been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
INSPECT TP SENSOR RESISTANCE
•  Turn the ignition switch off.
•  Disconnect the throttle body connector.
•  Measure the resistance between the following terminals (throttle body component side).
―  Throttle body terminal F and D: 700—1,800 ohms
―  Throttle body terminal F and E: 1,300—2,800 ohms
―  Throttle body terminal C and D: 1,000—2,400 ohms
―  Throttle body terminal C and E: 500—1,500 ohms
―  Throttle body terminal D and E: 700—2,100 ohms
•  Are all the resistances within specifications?
Yes
Go to the next step.
No
Replace the throttle body, then go to Step 6.
4
INSPECT TP SENSOR SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY
•  Turn the ignition switch to the ON position (Engine off).
•  Measure the voltage between the following circuits:
―  Throttle body terminal F (wiring harness-side) and body ground.
―  Throttle body terminal C (wiring harness-side) and body ground.
•  Are there voltage B+?
Yes
Repair or replace suspected part, then go to Step 6.
No
Go to the next step.
5
INSPECT TP SENSOR SIGNAL CIRCUITS FOR SHORT EACH OTHER
•  Turn the ignition switch off.
•  Disconnect the throttle body and PCM connector.
•  Measure resistance between throttle body terminal F and C.
•  Is the resistance more than 10 kilohms?
Yes
Go to the next step.
No
Repair or replace suspected part, then go to the next step.
6
VERIFY TROUBLESHOOTING OF DTC P2135 HAS BEEN COMPLETED
•  Verify that all disconnected connectors reconnected.
•  Clear the DTC from the PCM memory using the M‐MDS.
•  Start the engine.
•  Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
No
Go to the next step.
7
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
DTC troubleshooting completed.
