Code P0111 2017 Chevrolet Silverado Description
The P0111 diagnostic trouble code (DTC) for a 2017 Chevrolet Silverado indicates an issue with the Intake Air Temperature (IAT) sensor circuit. 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 that the IAT sensor's signal is out of the expected range or performance, it triggers the P0111 code.
Common Causes of P0111 2017 Chevrolet Silverado
- Faulty Intake Air Temperature (IAT) sensor
- Damaged wiring or connectors in the IAT circuit
- Corrosion or contamination in the IAT sensor
- ECM software issue
- Intake air leaks near the sensor
Symptoms of P0111 2017 Chevrolet Silverado
- Decreased fuel efficiency
- Rough idling or stalling
