DTC P0113 in Chevrolet vehicles indicates a high input from the Intake Air Temperature (IAT) sensor, potentially causing performance issues. This diagnostic trouble code often stems from a faulty IAT sensor, wiring problems, or ECM issues. Symptoms may include poor fuel economy, rough idling, and illumination of the check engine light.
To diagnose the problem, use an OBD-II scanner to confirm the code and inspect the IAT sensor and its wiring for visible damage. Testing the sensor with a multimeter can help determine if replacement is necessary. In some cases, cleaning the sensor or repairing wiring may resolve the issue.
Fixing DTC P0113 typically involves replacing the IAT sensor, repairing damaged wiring, or addressing vacuum leaks in the intake system. Regular maintenance and prompt attention to warning signs can help prevent this code from occurring.
