Throttle/Pedal Position Sensor "E" Minimum Stop Performance
P2116 indicates that the throttle/pedal position sensor E is not reaching its minimum voltage threshold when the accelerator pedal is fully released. This sensor failure prevents the engine control module from accurately detecting idle position, making the vehicle potentially undriveable and unsafe to operate.
What You Might Notice
- Lack of throttle response
- Limited or no acceleration
- Engine stall when idling
- Hesitation during acceleration
- Cruise control inoperative
Most Common Causes
- 1
Defective throttle/pedal position sensor
The sensor itself has failed or is not returning to minimum voltage at idle. This is the most common cause of P2116.
- 2
Wiring or connector issues
Corroded, damaged, or loose connections between the sensor and engine control module prevent proper signal transmission.
- 3
Accelerator pedal assembly failure
The pedal mechanism is stuck or mechanically binding, preventing it from returning to the minimum position.
- 4
Engine control module (ECM) fault
The ECM may have a software glitch or internal failure affecting how it reads the sensor signal.
How to Diagnose It
- 1
Check Defective throttle/pedal position sensor — The sensor itself has failed or is not returning to minimum voltage at idle. This is the most common cause of P2116.
- 2
Check Wiring or connector issues — Corroded, damaged, or loose connections between the sensor and engine control module prevent proper signal transmission.
- 3
Check Accelerator pedal assembly failure — The pedal mechanism is stuck or mechanically binding, preventing it from returning to the minimum position.
- 4
Check Engine control module (ECM) fault — The ECM may have a software glitch or internal failure affecting how it reads the sensor signal.
How to Fix It
- 1
Replace throttle/pedal position sensor E
Remove the faulty sensor and install a new one, ensuring proper calibration and connector seating. This resolves the majority of P2116 cases.
- 2
Inspect and repair wiring harness
Check the sensor connector and wiring for corrosion, damage, or loose connections. Repair or replace damaged wiring and clean corroded connectors.
- 3
Service or replace accelerator pedal assembly
Inspect the pedal mechanism for binding or mechanical damage. Clean or replace the pedal assembly if it cannot return fully to the minimum position.
- 4
Perform sensor calibration or ECM reprogramming
Use a diagnostic scanner to calibrate the sensor after replacement or reprogram the ECM if a software update is needed for the module to recognize proper sensor range.
