DTC P2135 [WL-C, WE-C (Australian, European (L.H.D. U.K.) specs.)]

DTC P2135	Accelerator pedal position (APP) sensor No.1/No.2 voltage correlation problem
DETECTION CONDITION	• The PCM monitors the input signals from accelerator pedal position sensor No.1 and accelerator pedal position sensor No.2. If the difference between accelerator pedal position sensor No.1 and accelerator pedal position sensor No.2 is more than 0.9 V for 0.5 s, the PCM determines that there is a malfunction in the accelerator pedal position sensor characteristic.
POSSIBLE CAUSE	• APP sensor malfunction • PCM malfunction

DTC P2135

Accelerator pedal position (APP) sensor No.1/No.2 voltage correlation problem

DETECTION CONDITION

• The PCM monitors the input signals from accelerator pedal position sensor No.1 and accelerator pedal position sensor No.2. If the difference between accelerator pedal position sensor No.1 and accelerator pedal position sensor No.2 is more than 0.9 V for 0.5 s, the PCM determines that there is a malfunction in the accelerator pedal position sensor characteristic.

POSSIBLE CAUSE

• APP sensor malfunction

• PCM malfunction

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	VERIFY CURRENT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT? • Connect the M-MDS to the DLC-2. • Clear the DTC from the PCM memory using the M-MDS. • Start the engine. • Is the same DTC present?	Yes	Go to the next step.
No	Intermittent concern exists. Perform the “INTERMITTENT CONCERN TROUBLESHOOTING”. (See INTERMITTENT CONCERN TROUBLESHOOTING [WL-C, WE-C].)
4	INSPECT APP SENSOR • Inspect the APP sensor. (See ACCELERATOR PEDAL POSITION (APP) SENSOR INSPECTION [WL-C, WE-C].) • Is there any malfunction?	Yes	Replace the APP sensor, then go to the next step.
No	Go to the next step.
5	VERIFY TROUBLESHOOTING OF DTC P2135 COMPLETED • Turn the engine switch off. • Make sure to reconnect all disconnected connectors. • Turn the engine switch to the ON position (Engine off). • Clear the DTC from the memory using the M-MDS. • Run the vehicle under the FREEZE FRAME DATA stored condition. • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [WL-C, WE-C].) (See PCM REMOVAL/INSTALLATION (U.K. Specs.) [WL-C, WE-C].)
No	Go to the next step.
6	VERIFY AFTER REPAIR PROCEDURE • Perform the “After Repair Procedure“. (See AFTER REPAIR PROCEDURE [WL-C, WE-C (Australian, European (L.H.D. U.K.) specs.)].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [WL-C, WE-C (Australian, European (L.H.D. U.K.) specs.)].)
No	DTC troubleshooting completed.
