The P2165: Throttle/Pedal Position Sensor ‘C’ Maximum Stop Performance refers to an issue where the throttle or pedal position sensor ‘C’ fails to properly register the maximum stop position. This issue can be caused by a faulty sensor, calibration problems, or mechanical issues with the throttle or pedal mechanism.
P2165 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P2165: Throttle/Pedal Position Sensor ‘C’ Maximum Stop Performance |
| Is it serious? | Yes, it can affect throttle response and vehicle acceleration, impacting drivability and safety. |
| Possible causes | – Faulty throttle/pedal position sensor ‘C’ – Sensor calibration issues – Mechanical problems with the throttle or pedal |
| How to diagnose? | – Test the throttle/pedal position sensor ‘C’ for performance issues – Verify sensor calibration – Inspect the throttle and pedal mechanism for issues |
P2165 Meaning
The P2165: Throttle/Pedal Position Sensor ‘C’ Maximum Stop Performance code indicates that the engine control module (ECM) has detected an issue with the maximum stop position of the throttle or pedal position sensor ‘C’. This sensor monitors the position of the throttle or pedal to control the amount of air entering the engine, which directly affects vehicle performance. A problem with this sensor can cause erratic throttle response and poor vehicle acceleration.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for additional related codes that may provide more insight into the issue. | OBD-II Scanner |
| Inspect Throttle and Pedal Mechanism | Visually inspect the throttle and pedal mechanism for any signs of wear, damage, or mechanical binding that could impact sensor performance. | Flashlight, Safety Gloves |
| Test Throttle/Pedal Position Sensor ‘C’ | Use a multimeter or diagnostic tool to test the throttle/pedal position sensor ‘C’ for performance issues. Compare readings with manufacturer specifications. | Multimeter, Diagnostic Tool |
| Verify Sensor Calibration | Check the calibration of the throttle/pedal position sensor ‘C’ to ensure it is functioning within manufacturer specifications. Recalibrate if necessary. | Calibration Tool (if needed) |
| Check for Mechanical Issues | Inspect the throttle body, linkage, and pedal assembly for mechanical issues that could interfere with sensor operation. | Flashlight, Wrenches |
| Repair or Replace Faulty Components | If the throttle/pedal position sensor ‘C’ or any related components are found to be faulty, repair or replace them as needed. | Replacement Parts, Tools |
| Clear the Code and Test Drive | After making repairs, clear the P2165 code using an OBD-II scanner and take the vehicle for a test drive to ensure the issue has been resolved. | OBD-II Scanner |
| Recheck for Codes | After the test drive, re-scan the vehicle to ensure that the P2165 code does not return. | OBD-II Scanner |
