Code P2122 2014 Chevrolet Silverado Description
The diagnostic trouble code P2122 on a 2014 Chevrolet Silverado relates to the Accelerator Pedal Position Sensor 1 Circuit registering low voltage. This sensor is responsible for monitoring the position of the accelerator pedal and transmitting this information to the engine control module (ECM) to adjust the fuel delivery and ignition timing accordingly. When the sensor detects low voltage, it indicates that there is an issue with the signal being sent to the ECM, which can lead to various performance issues.
Common Causes of P2122 2014 Chevrolet Silverado
- Damaged or corroded wiring leading to the Accelerator Pedal Position Sensor.
- A faulty Accelerator Pedal Position Sensor requiring replacement.
- Issues with the Engine Control Module (ECM) affecting sensor communication.
- Malfunctioning throttle body interfering with sensor signals.
- Environmental factors such as moisture or debris affecting sensor performance.
Symptoms of P2122 2014 Chevrolet Silverado
- Poor acceleration or lack of response when pressing the accelerator pedal.
- Engine hesitation or stumbling during acceleration.
- Illumination of the Check Engine Light on the dashboard.
- Reduced fuel efficiency due to improper fuel delivery.
- In extreme cases, the vehicle may go into "limp mode," limiting throttle response for safety reasons.
How to Fix P2122 2014 Chevrolet Silverado
- Begin by conducting a thorough inspection of the wiring and connectors leading to the Accelerator Pedal Position Sensor. Repair or replace any damaged components as needed.
- Test the sensor itself using a multimeter to ensure it is functioning correctly. If the sensor is faulty, replace it with a new one.
- Check the throttle body for any obstructions or malfunctions that may be affecting sensor signals. Clean or replace the throttle body if necessary.
- Reset the vehicle's ECM to clear the trouble code and allow for a fresh start. Perform a test drive to verify that the issue has been resolved.
- If the problem persists, consult a professional technician to further diagnose and address any underlying issues that may be causing the low voltage reading.
Cost to Fix P2122 2014 Chevrolet Silverado
The typical repair costs for addressing the P2122 code on a 2014 Chevrolet Silverado can range from $150 to $500, depending on the specific cause of the issue and the cost of parts and labor. This estimate includes the price of a new Accelerator Pedal Position Sensor, potential wiring repairs, and diagnostic labor.

Code 2122
Accelerator position sensor is basically just a new gas petal, at least for a chevy Silverado,
bought at O 'Reillys Auto Parts store (not online). for around $100, simply two bolts and plug and play switch built in. Got me out of (LIMP Mode)-Reduce of engine power-
You’re right that on many Silverados the accelerator pedal assembly includes the position sensors, so replacing the pedal can fix a P2122 and get the truck out of reduced power mode. It’s a fairly common repair and usually is plug-and-play like you described.
The only thing I’d add for others reading this is that P2122 isn’t always the pedal itself. The code means the ECM is seeing low voltage on that circuit, and that can also be caused by wiring damage, a poor connector, or low reference voltage from the computer. If someone replaces the pedal and the code comes back, the next step is checking the harness and the 5-volt reference circuit.
But in a lot of real-world cases, especially when the truck suddenly drops into limp mode with no other electrical issues, the pedal assembly is the culprit and your fix is exactly what solves it.
Glad it got you back on the road.
