P2114: Throttle/Pedal Position Sensor C Minimum Stop Performance

What it means

The module detects that throttle or pedal position sensor C does not behave as expected at its minimum stop. It sets the code when the sensor reading or its relationship to the expected minimum position falls outside the calibrated range.

How it works

Sensor C is one of the position signals the control module uses to track throttle or pedal movement. The module checks how this signal behaves at its minimum stop and sets P2114 when the reading, or its relationship to the expected minimum, falls outside the calibrated range.

Common causes

Most likely first.

1. Faulty position sensor
2. Throttle body contamination or sticking
3. Damaged wiring or connector
4. Throttle actuator fault
5. Control module fault

Symptoms

• Check engine light
• Reduced engine power
• Poor or uneven acceleration
• Limp mode

How to diagnose it

1. Use a scan tool to record freeze-frame data and compare sensor C with the other position signals at rest, since the fault concerns the minimum-stop reading.
2. Inspect the throttle body or pedal assembly identified by the vehicle’s wiring information, checking sensor C’s connector and wiring for looseness, corrosion, damage, or chafing.
3. With the ignition on and engine off, slowly move the pedal while watching sensor C live data for a smooth change and a plausible minimum reading; compare it with the other channels.
4. If the code points to the throttle body, inspect for deposits or sticking that could keep the plate from reaching its minimum position; do not force an electronic throttle plate.
5. Test sensor C’s reference, ground, and signal circuits against the manufacturer’s specification, then check actuator operation if the wiring and sensor readings are sound.
6. Consider a control-module fault only after the sensor, throttle mechanism, actuator, and circuits have passed their checks.

Common fixes

• Repair a loose, corroded, or damaged sensor C connector or wiring.
• Clean deposits from a sticking throttle body using the vehicle maker’s approved method.
• Replace the faulty position sensor or assembly if sensor C fails its circuit or signal checks.
• Repair or replace the throttle actuator if it cannot move the plate as commanded.
• Repair or replace the control module only after confirming its circuits and outputs are faulty.

Can I keep driving?

Reduced power or limp mode can make acceleration unpredictable, so avoid fast traffic, overtaking, and long trips. If throttle response is severely limited or uneven, stop somewhere safe and arrange help.
