P2114Throttle/Pedal Position Sensor 'C' Minimum Stop Performance

Q: What does code P2114 mean?

Throttle/Pedal Position Sensor 'C' Minimum Stop Performance. P2114 indicates that the engine control module (ECM) has detected a performance problem with the minimum stop position of throttle/pedal position sensor 'C', which is typically part of a redundant or secondary throttle position sensing circuit. The ECM expects a specific voltage or signal from sensor 'C' when the throttle plate is fully closed, and the signal falls outside the acceptable range or does not match the other throttle position sensors.

Symptoms you may notice

Illumination of the check engine light, often with no other noticeable symptoms
Reduced engine power or limp mode, limiting acceleration
Poor throttle response or hesitation when accelerating from a stop
Unstable or fluctuating idle speed
Transmission may shift harshly or refuse to downshift due to reduced engine torque signal

Common causes, most likely first

Carbon buildup or mechanical obstruction on the throttle plate or bore preventing it from reaching the closed stop
Faulty throttle position sensor 'C' or its internal circuitry
Wiring damage (open, short, or high resistance) in the sensor 'C' signal or reference circuit
Corroded or loose electrical connector at the throttle body or pedal assembly
Throttle body adaptation or calibration lost or corrupted in the ECM
Failed throttle actuator control motor not allowing the plate to return to the minimum stop
ECM internal fault incorrectly interpreting the sensor signal

How to diagnose and fix it

Use an OBD-II scan tool to read live data for all throttle position sensors and compare sensor 'C' voltage at closed throttle to the specified range
Visually inspect the throttle body bore and plate for carbon deposits or debris, and clean with throttle body cleaner if necessary
Check the sensor 'C' connector and wiring for corrosion, loose pins, or chafed insulation, and repair as needed
Perform a throttle body adaptation or relearn procedure using the scan tool after cleaning or replacement
Measure resistance and voltage on the sensor 'C' circuit according to the manufacturer's diagnostic flow chart
Replace the throttle position sensor or throttle body assembly if electrical tests confirm an internal failure
Clear the code and verify the repair by test-driving and confirming the minimum stop value reads correctly

Why throttle body cleaning often fixes P2114

A dirty throttle plate that cannot fully close is one of the most common causes of this code, and cleaning the bore often resolves it without any parts replacement.
Many technicians replace the throttle body unnecessarily when the real problem is a worn engine mount or misadjusted throttle cable that prevents the plate from reaching its stop.
The ECM may set P2114 after a battery replacement or throttle body cleaning if the learned minimum stop value is not relearned, so always perform the adaptation procedure.
Sensor 'C' is often part of a redundant circuit, and a failure in the primary sensor can cause the ECM to compare signals and falsely flag sensor 'C' as out of range.
This code can be set by a vacuum leak or intake air leak that changes the closed-throttle airflow, causing the ECM to see an unexpected minimum stop position.

Can I keep driving with P2114?

You can usually drive the vehicle to a repair shop, but expect reduced power and possible limp mode; avoid heavy acceleration or highway merging until the fault is repaired.
