Throttle/Pedal Position Sensor "C" Minimum Stop Performance
P2114 indicates that Throttle/Pedal Position Sensor C is reading below its minimum expected voltage or position threshold. This sensor is critical for engine control, and when it fails, the engine control module cannot properly interpret throttle commands, making the vehicle potentially undriveable.
What You Might Notice
- Lack of throttle response when pressing accelerator pedal
- Limited or no acceleration despite throttle input
- Engine stalling during idle or at stops
- Hesitation or surging when accelerating
- Cruise control system inoperative
Most Common Causes
- 1
Defective Throttle Position Sensor C
The sensor itself has failed electrically or mechanically, causing it to send below-minimum voltage signals to the ECM.
- 2
Wiring or Connector Issues
Corroded, loose, or damaged wiring harness or connector pins between the sensor and ECM preventing proper signal transmission.
- 3
ECM or TCM Software Malfunction
Engine or transmission control module software glitch or calibration error misinterpreting valid sensor signals.
- 4
Stuck or Mechanically Bound Throttle Linkage
Physical obstruction or binding in the throttle body mechanism preventing the sensor from reaching proper operating range.
How to Diagnose It
- 1
Check Defective Throttle Position Sensor C — The sensor itself has failed electrically or mechanically, causing it to send below-minimum voltage signals to the ECM.
- 2
Check Wiring or Connector Issues — Corroded, loose, or damaged wiring harness or connector pins between the sensor and ECM preventing proper signal transmission.
- 3
Check ECM or TCM Software Malfunction — Engine or transmission control module software glitch or calibration error misinterpreting valid sensor signals.
- 4
Check Stuck or Mechanically Bound Throttle Linkage — Physical obstruction or binding in the throttle body mechanism preventing the sensor from reaching proper operating range.
How to Fix It
- 1
Replace Throttle Position Sensor C
Remove and replace the defective throttle/pedal position sensor with a new OEM or quality replacement sensor.
- 2
Inspect and Repair Wiring Harness
Check all wiring from the sensor to the ECM for corrosion, damage, or loose connections. Repair or replace damaged sections and reseat connectors firmly.
- 3
Clean or Replace Throttle Body
Inspect the throttle body for carbon buildup, debris, or mechanical binding that may prevent sensor operation. Clean or replace as needed.

Flash ECM/TCM Software Update
Contact the vehicle manufacturer or dealership to check for available software updates or recalibration procedures that may resolve sensor interpretation issues.
