DTC P2135 [13B-MSP]

DIAGNOSTIC PROCEDURE

DTC P2135	TP sensor No. 1/No. 2 voltage correlation problem
DETECTION CONDITION	The PCM compares the input voltage from TP sensor No. 1 with the input voltage from TP sensor No. 2 when the engine is running. If the difference is more than the specification, the PCM determines that there is a TP sensor No. 1/No. 2 voltage correlation problem. Diagnostic support note This is a continuous monitor (CCM.) The MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle. FREEZE FRAME DATA is available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	Connector or terminal malfunction TP sensor No. 1 malfunction TP sensor No. 2 malfunction PCM malfunction

DTC P2135

TP sensor No. 1/No. 2 voltage correlation problem

DETECTION CONDITION

The PCM compares the input voltage from TP sensor No. 1 with the input voltage from TP sensor No. 2 when the engine is running. If the difference is more than the specification, the PCM determines that there is a TP sensor No. 1/No. 2 voltage correlation problem.
Diagnostic support note
This is a continuous monitor (CCM.)
The MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle.
FREEZE FRAME DATA is available.
The DTC is stored in the PCM memory.

POSSIBLE CAUSE

Connector or terminal malfunction
TP sensor No. 1 malfunction
TP sensor No. 2 malfunction
PCM malfunction

DTC REFERENCE CHART

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED Has FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY Verify related Service Bulletins and/or on-line repair information availability. Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	INSPECT THROTTLE BODY CONNECTOR FOR POOR CONNECTION Turn the ignition switch off. Disconnect the throttle body connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion.) Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 6.
3		No	Go to the next step.
4	INSPECT TP SENSOR No. 1/No. 2 Inspect the TP sensor, No. 1/No. 2. (See THROTTLE POSITION (TP) SENSOR INSPECTION [13B-MSP] .) Is there any malfunction?	Yes	Replace the throttle body, then go to Step 6. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [13B-MSP] .)
4		No	Go to the next step.
5	INSPECT PCM CONNECTOR FOR POOR CONNECTION Turn the ignition switch off. Disconnect the PCM connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion.) Is there any malfunction?	Yes	Repair or replace the terminal, then go to the next step.
5		No	Go to the next step.
6	VERIFY TROUBLESHOOTING OF DTC P2135 COMPLETED Make sure to reconnect all disconnected connectors. 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. (See PCM REMOVAL/INSTALLATION [13B-MSP] .)
6		No	Go to the next step.
7	VERIFY AFTER REPAIR PROCEDURE. Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [13B-MSP] .) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [13B-MSP] .)
7		No	DTC troubleshooting completed.
