This summary uses the existing diagnostic information shown in full below.
The car's computer is getting a signal from the pedal sensor that is too high, like when you press the gas pedal too hard, but you aren't actually doing that.
The Pedal Position Sensor 'B' is sending a voltage signal to the car's computer that is higher than expected.
The Pedal Position Sensor 'B' is responsible for sending the position of the accelerator pedal to the engine control module (ECM). If the voltage signal from this sensor is higher than the pre-set range, the ECM will set the P1DFE code.
• Check Engine Light is on
• Unresponsive or erratic throttle response
• Poor fuel economy
• Faulty Pedal Position Sensor 'B'
• Wiring issues such as shorts or open circuits
• Faulty ECM
ECM: Engine Control Module
OBD-II: On-Board Diagnostics, second generation
• Use an OBD-II scanner to confirm the P1DFE code
• Inspect the wiring and connectors for damage
• Test the Pedal Position Sensor 'B' voltage output
• Replace the Pedal Position Sensor 'B'
• Repair or replace damaged wiring or connectors
• Reprogram or replace the ECM if necessary
• OBD-II Scanner
• Multimeter
• Screwdriver set

Moderate
• Dodge Charger
• Chrysler 300
• Jeep Grand Cherokee
• Regularly inspect wiring and connectors
• Perform routine maintenance checks
• Avoid harsh driving conditions
Sensor Issue
• Do not ignore the Check Engine Light
• Have the vehicle inspected by a professional
• Avoid driving aggressively until the issue is resolved
Check with your vehicle manufacturer for specific warranty coverage on sensors.
This code is relatively uncommon and typically associated with specific makes and models.
Moderate – While the vehicle may still be drivable, it is important to address this issue to avoid further complications.
Driving with a malfunctioning pedal position sensor can lead to unsafe driving conditions.
• Vehicle at operating temperature
• Engine running and vehicle stationary
The Pedal Position Sensor 'B' is located on the accelerator pedal assembly.
Q: Can I drive my car with a P1DFE code?
A: It is possible to drive, but it is not recommended as it can lead to unsafe driving conditions.
Q: How do I clear the P1DFE code?
A: The code can be cleared using an OBD-II scanner after the issue has been fixed.
