Unraveling Code P0113 in Chevrolet Vehicles
When your Chevy’s onboard diagnostics detect an issue with the Intake Air Temperature (IAT) sensor circuit, it triggers Code P0113. This code specifically indicates a high input from the IAT sensor circuit, suggesting a potential malfunction in the sensor or its associated wiring.
The IAT sensor is crucial for your vehicle’s engine management system, measuring incoming air temperature to allow the Engine Control Module (ECM) to optimize the fuel mixture. A malfunctioning sensor can lead to poor engine performance, reduced fuel efficiency, and increased emissions.
Common Culprits Behind Code P0113
- Faulty IAT sensor
- Wiring issues (damage, corrosion, loose connections)
- Sensor contamination
- ECM malfunctions
- Vacuum leaks in the intake system
Diagnosing and Resolving Code P0113
