Throttle/Pedal Position Sensor "F" Minimum Stop Performance
P2117 indicates the throttle/pedal position sensor F is reading below its minimum expected voltage, preventing the engine control module from properly interpreting throttle input. This can render the vehicle undriveable or cause sudden loss of engine power, creating a serious safety hazard.
What You Might Notice
- Lack of throttle response
- Limited or no acceleration
- Engine stall during idle
- Hesitation when accelerating
- Cruise control inoperative
Most Common Causes
- 1
Defective throttle/pedal position sensor
The sensor has failed electrically or mechanically, sending a signal below the minimum voltage threshold to the ECM.
- 2
Corroded or damaged sensor connector
Corrosion or loose connections at the sensor plug prevent proper voltage signal transmission.
- 3
Broken or shorted wiring to sensor
Damaged wiring harness or internal short circuit causes the sensor signal to drop below minimum operating voltage.
- 4
Electronic control module (ECM) malfunction
A faulty ECM may incorrectly interpret sensor signals or fail to receive proper voltage from the sensor circuit.
How to Diagnose It
- 1
Check Defective throttle/pedal position sensor — The sensor has failed electrically or mechanically, sending a signal below the minimum voltage threshold to the ECM.
- 2
Check Corroded or damaged sensor connector — Corrosion or loose connections at the sensor plug prevent proper voltage signal transmission.
- 3
Check Broken or shorted wiring to sensor — Damaged wiring harness or internal short circuit causes the sensor signal to drop below minimum operating voltage.
- 4
Check Electronic control module (ECM) malfunction — A faulty ECM may incorrectly interpret sensor signals or fail to receive proper voltage from the sensor circuit.
How to Fix It
- 1
Replace throttle/pedal position sensor
Remove the old sensor from the throttle body or pedal assembly and install a new OEM or quality replacement sensor, ensuring proper voltage signal to the ECM.
- 2
Repair sensor connector and wiring
Inspect the sensor connector for corrosion and clean or replace as needed. Check the wiring harness for damage and repair or replace any broken sections.
- 3
Test ECM power and ground circuits
Verify the ECM is supplying proper reference voltage (usually 5V) to the sensor and that ground connections are clean and secure.
- 4
Replace electronic control module if faulty
If sensor and wiring test good but code persists, the ECM itself may be defective and require replacement or reprogramming.
