This code means that the car's computer is having trouble talking to the pedal position sensor, which tells the car how much you are pressing the gas pedal.
The P1768 code is triggered when the vehicle's control module detects a timeout in the communication with the pedal position sensor via the CAN bus.
The CAN (Controller Area Network) bus is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other without a host computer. The pedal position sensor provides data to the vehicle's control module about the position of the accelerator pedal. If there is a delay or timeout in this communication, the P1768 code is set.
• Check Engine Light is on
• Reduced engine performance
• Unresponsive accelerator pedal
• Faulty pedal position sensor
• Wiring issues or poor connections in the CAN bus
• Faulty control module
CAN: Controller Area Network
OBD-II: On-Board Diagnostics II
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connections related to the pedal position sensor.
• Test the pedal position sensor for proper operation.
• Repair or replace the pedal position sensor.
• Fix any damaged wiring or poor connections.
• Replace the control module if necessary.

Moderate
• Vehicle 1
• Vehicle 2
• Vehicle 3
• Regularly inspect and maintain wiring connections.
• Ensure the pedal position sensor is clean and free of debris.
• Perform routine vehicle diagnostics.
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if you notice performance issues.
Check with your vehicle manufacturer for warranty coverage on the pedal position sensor and related components.
The P1768 code has been associated with communication issues in vehicles using CAN bus systems since the early 2000s.
Moderate – It's important to address this issue to ensure proper vehicle performance.
Driving with a malfunctioning pedal position sensor can lead to reduced performance and safety risks.
• Vehicle at operating temperature
• Engine running
The pedal position sensor is typically located near the accelerator pedal assembly.
Q: Can I drive with a P1768 code?
A: It's not recommended as it can lead to reduced performance and safety issues.
Q: How do I reset the P1768 code?
A: Fix the underlying issue first, then use an OBD-II scanner to clear the code.
