Code P0113 2014 GMC Sierra Description

The intake air temperature (IAT) sensor 1 is a variable resistor that measures the temperature of the air in the sensor bore. The Engine Control Module (ECM) supplies 5 V to the IAT sensor 1 signal circuit and a ground for the IAT sensor 1 low reference circuit. The signal varies with inlet air temperature and is displayed by the scan tool as °C (°F). The multifunction intake air sensor houses the IAT sensor 1, IAT sensor 2, Humidity sensor, Mass Air Flow (MAF) sensor and BARO pressure sensor. The Diagnostic Trouble Code (DTC) ECM detects that the IAT sensor 1 signal is colder than -60°C (-76°F) for greater than 5 s.

Frequently Asked Questions about P0113 2014 GMC Sierra Code

1. What does the OBDII code P0113 mean on a 2014 GMC Sierra?

P0113 indicates that the Intake Air Temperature (IAT) sensor is reporting a voltage level higher than expected, which usually means the sensor is detecting an abnormally high temperature or thereâ€™s an electrical issue.

2. What are the common symptoms of P0113 in a 2014 GMC Sierra?

Symptoms may include poor engine performance, reduced fuel efficiency, rough idling, difficulty starting, or an illuminated check engine light.

3. What causes the P0113 code in a 2014 GMC Sierra?

Common causes include a faulty IAT sensor, a damaged or disconnected IAT sensor wiring harness, a short circuit, or a dirty or contaminated sensor.

4. Can I drive my 2014 GMC Sierra with a P0113 code?

You can drive with a P0113 code, but it is not recommended for long periods. The engine may run inefficiently, and prolonged driving without repair could lead to further issues.

5. How do I fix the P0113 code on my 2014 GMC Sierra?

Fixes include inspecting and reconnecting the IAT sensor wiring, cleaning the sensor, or replacing the sensor if itâ€™s faulty. Checking for and repairing any wiring damage is also essential.

6. Where is the IAT sensor located on a 2014 GMC Sierra?

The IAT sensor is typically located near the air intake system, often on or near the air filter housing or intake manifold.

7. How much does it cost to fix the P0113 code on a 2014 GMC Sierra?

Repair costs can range from $50 to $200, depending on whether the issue is resolved by cleaning, repairing wiring, or replacing the IAT sensor.

8. Can a dirty air filter cause the P0113 code on a 2014 GMC Sierra?

A dirty air filter is unlikely to cause P0113 directly, but it can affect airflow and sensor readings. Cleaning or replacing the air filter is a good maintenance step.

9. Will resetting the code fix the P0113 issue in my 2014 GMC Sierra?

Resetting the code may turn off the check engine light temporarily, but if the underlying issue isnâ€™t resolved, the code will return.

10. How can I prevent the P0113 code from occurring in my 2014 GMC Sierra?

Regular maintenance, including checking the air intake system for damage, cleaning the IAT sensor, and inspecting wiring, can help prevent the P0113 code.
