Laymans terms

This code means that the car's computer thinks the gas pedal isn't working right. It's like when you press a button and it doesn't do what it's supposed to.

Explanation

The P2165 code is triggered when the Engine Control Module (ECM) detects that the throttle or pedal position sensor C is not reaching its maximum stop position as expected.

Technical description

The throttle/pedal position sensor C is responsible for monitoring the position of the throttle or pedal. When the ECM detects that the sensor does not reach its maximum stop position, it sets the P2165 code. This could be due to a malfunctioning sensor, wiring issues, or a problem with the throttle body.

Symptoms

• Check Engine Light is on

• Reduced engine performance

• Unresponsive throttle

Common Causes

• Faulty throttle/pedal position sensor C

• Wiring issues or poor connections

• Malfunctioning throttle body
