P0114 2015 GMC Sierra Code - Intake Air Temperature Circuit Intermittent
Quick Answer
The P0114 code on a 2015 GMC Sierra indicates an issue with the Intake Air Temperature (IAT) Circuit being intermittent. Common causes include Faulty IAT Sensor: The sensor itself may be malfunctioning, providing inconsistent temperature readings, Damaged Wiring or Connectors: Broken or corroded wires or connectors in the IAT circuit can disrupt the signal transmission, Corroded or Dirty Sensor: Build-up of dirt, debris, or corrosion on the IAT sensor can interfere with its operation. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0114 2015 GMC Sierra Description
The P0114 code on a 2015 GMC Sierra indicates an issue with the Intake Air Temperature (IAT) Circuit being intermittent. The Intake Air Temperature sensor is responsible for measuring the temperature of the air entering the engine. This information is crucial for the engine control module (ECM) to adjust fuel delivery and ignition timing to optimize engine performance and efficiency. When the ECM detects an intermittent circuit issue with the IAT sensor, it means that there are inconsistencies or disruptions in the sensor's signal transmission, which can lead to inaccurate temperature readings.
Common Causes of P0114 2015 GMC Sierra
- Faulty IAT Sensor: The sensor itself may be malfunctioning, providing inconsistent temperature readings.
- Damaged Wiring or Connectors: Broken or corroded wires or connectors in the IAT circuit can disrupt the signal transmission.
- Corroded or Dirty Sensor: Build-up of dirt, debris, or corrosion on the IAT sensor can interfere with its operation.
- Malfunctioning ECM: A problem with the engine control module can prevent proper communication with the IAT sensor, leading to intermittent circuit issues.
Symptoms of P0114 2015 GMC Sierra
- Check Engine Light: The most common symptom associated with the P0114 code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Poor Fuel Economy: A faulty IAT sensor can cause the engine to run rich or lean, resulting in decreased fuel efficiency.
- Rough Idling: Inaccurate temperature readings can lead to erratic engine idling, causing vibrations and instability.
- Engine Stalling: The ECM may struggle to adjust fuel delivery properly, leading to potential engine stalling at idle or low speeds.
- Decreased Engine Performance: The vehicle may experience a loss of power, slower acceleration, or difficulty maintaining speed due to improper fuel mixture.
How to Fix P0114 2015 GMC Sierra
- Diagnose the Issue: Use a diagnostic scan tool to retrieve the fault code and perform tests to pinpoint the exact cause of the intermittent circuit issue.
- Inspect Wiring and Connectors: Check the wiring and connectors in the IAT circuit for any damage, corrosion, or loose connections. Repair or replace as necessary.
- Test the IAT Sensor: Test the Intake Air Temperature sensor for proper operation and accuracy. Replace the sensor if it is faulty.
- Clear the Codes: Once the issue is repaired, clear the fault codes from the ECM memory and reset the Check Engine Light.
- Test Drive: After the repair is complete, test drive the vehicle to ensure that the issue has been resolved and that the engine is operating correctly.
Cost to Fix P0114 2015 GMC Sierra
The typical repair costs for addressing a P0114 code on a 2015 GMC Sierra can vary depending on the specific cause of the issue. On average, the cost of replacing an Intake Air Temperature sensor ranges from $50 to $150, while repairing wiring or connectors can cost between $100 and $200. Labor rates at auto repair shops can range from $80 to $150 per hour, and the total repair cost may also include diagnostic time and any additional parts needed. It is recommended to consult with a qualified mechanic or shop for a more accurate estimate based on the vehicle's make and model, as well as the extent of the repair required.
