P0113 2015 GMC Sierra Code - Intake Air Temperature Circuit High Input
Quick Answer
The P0113 diagnostic trouble code (DTC) for a 2015 GMC Sierra indicates an issue with the Intake Air Temperature (IAT) sensor circuit registering a high input. Common causes include Faulty IAT Sensor: The IAT sensor itself may be malfunctioning, providing incorrect temperature readings to the ECM, Damaged Wiring or Connectors: Corrosion, fraying, or disconnection in the wiring or connectors of the IAT sensor circuit can lead to high input readings, ECM Issues: A malfunctioning ECM may misinterpret the signals from the IAT sensor, triggering the high input code. 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 P0113 2015 GMC Sierra Description
The P0113 diagnostic trouble code (DTC) for a 2015 GMC Sierra indicates an issue with the Intake Air Temperature (IAT) sensor circuit registering a high input. The IAT 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 the air-fuel mixture for optimal combustion. When the ECM detects a high input from the IAT sensor circuit, it means that the recorded temperature is higher than expected, potentially leading to incorrect fuel delivery and ignition timing.
Common Causes of P0113 2015 GMC Sierra
- Faulty IAT Sensor: The IAT sensor itself may be malfunctioning, providing incorrect temperature readings to the ECM.
- Damaged Wiring or Connectors: Corrosion, fraying, or disconnection in the wiring or connectors of the IAT sensor circuit can lead to high input readings.
- ECM Issues: A malfunctioning ECM may misinterpret the signals from the IAT sensor, triggering the high input code.
- Intake Air Leaks: Air leaks in the intake system can affect the IAT sensor readings, causing erroneous high input signals.
- Extreme Temperature Conditions: Operating the vehicle in extreme temperature conditions can sometimes cause the IAT sensor to register high temperatures inaccurately.
Symptoms of P0113 2015 GMC Sierra
- Check Engine Light: The most common symptom associated with this code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Decreased Fuel Efficiency: A malfunctioning IAT sensor can lead to incorrect fuel delivery, resulting in decreased fuel efficiency.
- Engine Performance Issues: The vehicle may experience rough idling, hesitation, or a lack of power due to incorrect air-fuel mixture.
- Emission Problems: Incorrect combustion caused by a high input from the IAT sensor can lead to increased emissions, potentially causing the vehicle to fail emissions tests.
How to Fix P0113 2015 GMC Sierra
- Diagnose the Issue: Use a scan tool to retrieve the DTC and perform a thorough inspection of the IAT sensor, wiring, and connectors to identify the root cause of the high input signal.
- Replace the IAT Sensor: If the sensor is found to be faulty, replace it with a new, OEM-quality sensor to ensure accurate temperature readings.
- Repair Wiring or Connectors: Repair or replace any damaged wiring or connectors in the IAT sensor circuit to restore proper functionality.
- Clear DTC and Test Drive: After completing the repairs, clear the DTC from the ECM memory and test drive the vehicle to ensure that the issue has been resolved.
- Monitor Performance: Keep an eye on the vehicle's performance, fuel efficiency, and emissions after the repair to verify that the problem has been successfully addressed.
Cost to Fix P0113 2015 GMC Sierra
The typical repair costs for addressing a P0113 code on a 2015 GMC Sierra can vary depending on the specific cause of the issue. Replacing the IAT sensor itself can cost between $50 and $100, while repairing wiring or connectors may add additional labor charges. Overall, the total repair cost, including parts and labor, can range from $100 to $300. It's important to note that diagnostic time and labor rates at auto repair shops can vary, so it's advisable to check with local service providers for a more accurate estimate based on your location and vehicle details.
