P2131 Dodge Code - Throttle/Pedal Position Sensor/Switch 'F' Circuit

Quick Answer

The Accelerator Pedal Position (APP) sensor is an input to the Powertrain Control Module (PCM) and used to determine the amount of torque requested by the operator. Common causes include Faulty Accelerator Pedal Position (APP) Sensor, Accelerator Pedal Position (APP) Sensor harness is open or shorted, Accelerator Pedal Position (APP) Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2131 Dodge Description

The Accelerator Pedal Position (APP) sensor is an input to the Powertrain Control Module (PCM) and used to determine the amount of torque requested by the operator. There are 2 pedal position signals in the sensor. Both signals, APP and APP2, have a positive slope (increasing angle, increasing voltage), but are offset and increase at different rates. The 2 pedal position signals make sure the PCM receives a correct input even if 1 signal has a concern. The PCM determines if a signal is incorrect by calculating where it should be, inferred from the other signals. If a concern is present with one of the circuits the other input is used. There are 2 reference voltage circuits, 2 signal return circuits, and 2 signal circuits (a total of 6 circuits and pins) between the PCM and the APP sensor assembly. The pedal position signal is converted to pedal travel degrees (rotary angle) by the PCM. The software converts these degrees to counts, which is the input to the torque based strategy.

Frequently Asked Questions about P2131 Dodge Code

What does the OBDII code P2131 mean on a Dodge vehicle?

P2131 indicates a problem with the Throttle/Pedal Position Sensor/Switch 'F' Circuit, which monitors the position of the throttle or pedal to ensure proper engine performance.

What are the symptoms of code P2131 on a Dodge?

Common symptoms include reduced engine performance, a stuck throttle, poor acceleration, the check engine light turning on, and possibly the vehicle entering "limp mode."

What causes the P2131 code on a Dodge?

Possible causes include a faulty throttle position sensor, damaged wiring or connectors, issues with the throttle body, or a malfunctioning engine control module (ECM).

Can I drive my Dodge with the P2131 code?

Driving with the P2131 code is not recommended, as it can lead to poor performance, unsafe driving conditions, or further damage to the throttle control system.

How do I diagnose the P2131 code on a Dodge?

Start by using an OBDII scanner to confirm the code, then inspect the throttle position sensor, wiring, and connectors for damage or corrosion. Test the sensor's voltage and resistance if necessary.

How do I fix the P2131 code on a Dodge?

Repairs may include replacing the throttle position sensor, repairing or replacing damaged wiring, cleaning the throttle body, or reprogramming or replacing the ECM.

What tools are needed to fix the P2131 code?

You’ll typically need an OBDII scanner, a multimeter for testing electrical circuits, and basic hand tools for removing and replacing components.

How much does it cost to fix the P2131 code on a Dodge?

Repair costs vary but may range from $100 to $400, depending on whether the issue is a sensor replacement, wiring repair, or throttle body cleaning.

Can a dirty throttle body cause the P2131 code?

Yes, a dirty or clogged throttle body can interfere with sensor readings and trigger the P2131 code. Cleaning the throttle body may resolve the issue in some cases.

Do I need to clear the P2131 code after repairs?

Yes, after completing repairs, clear the code with an OBDII scanner and test drive the vehicle to ensure the issue is resolved and the code does not return.
