• Solutions

The P2165 code indicates an issue with the Throttle/Pedal Position Sensor C. This sensor monitors the position of the throttle and the driver's accelerator pedal, providing feedback to the engine control module (ECM). When the sensor's maximum stop performance is compromised, it can lead to poor engine performance and potential safety risks.

What are the symptoms of the P2165 code?

When the P2165 code is triggered, you may experience:

• Check Engine Light illuminated on the dashboard
• Unresponsive throttle or erratic engine performance
• Reduced engine power or acceleration issues
• Stalling or hesitation during acceleration

What causes the P2165 code?

Several factors can lead to the P2165 fault code, including:

• Failed or malfunctioning throttle pedal position sensor
• Damaged wiring or connectors associated with the throttle position sensor
• Faulty ECM settings or programming errors
• Mechanical issues with the throttle body itself

How to fix P2165?

To resolve the P2165 code, consider the following steps:

• Inspect the throttle/pedal position sensor for any physical damage or wear.
• Check wiring and connectors for signs of fraying, corrosion, or disconnection.
• Test the throttle position sensor with a multimeter to ensure it operates within the specified range.
• If necessary, replace the throttle/pedal position sensor, repair any wiring issues, and clear the fault code.
• Finally, verify that no other diagnostic trouble codes are present before finalizing repairs.
