DTC P2138:00 [L8, LF, L5]

DTC P2138:00	APP sensor No.1/No.2 voltage correlation problem
DETECTION CONDITION	• The PCM compares the input voltage from APP sensor No.1 with the input voltage from APP sensor No.2 when the engine is running. If the difference is more than the specification, the PCM determines that there is an APP sensor No.1/No.2 angle correlation problem. Diagnostic support note • This is a continuous monitor (CCM). • MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle. • FREEZE FRAME DATA is available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE	• APP sensor No.1 malfunction • APP sensor No.2 malfunction • Connector or terminal malfunction • PCM malfunction

DTC P2138:00

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

DETECTION CONDITION

• The PCM compares the input voltage from APP sensor No.1 with the input voltage from APP sensor No.2 when the engine is running. If the difference is more than the specification, the PCM determines that there is an APP sensor No.1/No.2 angle correlation problem.

Diagnostic support note

• This is a continuous monitor (CCM).

• MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.

• FREEZE FRAME DATA is available.

• The DTC is stored in the PCM memory.

POSSIBLE CAUSE

• APP sensor No.1 malfunction

• APP sensor No.2 malfunction

• Connector or terminal malfunction

• PCM malfunction

STEP	INSPECTION	ACTION
1	VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
No	Record the FREEZE FRAME 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 POOR CONNECTION OF APP SENSOR CONNECTOR • Switch the ignition to off. • Disconnect the APP sensor connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the terminal and/or connector, then go to Step 6.
No	Go to the next step.
4	INSPECT APP SENSOR • Inspect the APP sensor. (See ACCELERATOR PEDAL POSITION (APP) SENSOR INSPECTION [L8, LF, L5].) • Is there any malfunction?	Yes	Replace the accelerator pedal, then go to Step 6. (See ACCELERATOR PEDAL REMOVAL/INSTALLATION [L8, LF, L5].)
No	Go to the next step.
5	INSPECT POOR CONNECTION OF PCM CONNECTOR • Switch the ignition to 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 and/or connector, then go to the next step.
No	Go to the next step.
6	VERIFY TROUBLESHOOTING OF DTC P2138:00 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 [L8, LF, L5].)
No	Go to the next step.
7	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [L8, LF, L5].) • Is any DTC present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [L8, LF, L5].)
No	DTC troubleshooting completed.
