DTC P2135:00 [MZI-3.7]

id0102d2708700

DTC P2135:00 | 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 | • TP sensor malfunction • Short to power supply between TP sensor No.1 terminal F and PCM terminal 2AN • Short to power supply between TP sensor No.2 terminal C and PCM terminal 2AL • TP sensor circuits are shorted each other

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. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZI-3.7].)
4 | INSPECT TP SENSOR SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY • Throttle body connector is disconnected. • 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 • Throttle body connector is disconnected. • Turn the ignition switch off. • Disconnect the 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 P2135:00 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 | Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [MZI-3.7].) Go to the next step.
No | Go to the next step.
7 | VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZI-3.7].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [MZI-3.7].)
No | Troubleshooting completed.
