Code P0072 2017 Chevrolet Silverado Description
The P0072 diagnostic trouble code (DTC) for a 2017 Chevrolet Silverado indicates that there is a low voltage condition detected in the circuit of the Ambient Air Temperature (AAT) sensor. The AAT sensor is responsible for measuring the outside air temperature and providing this information to the engine control module (ECM) to adjust various engine functions accordingly. When the voltage in the circuit is lower than expected, it can lead to inaccurate temperature readings and affect the vehicle's performance.
Common Causes of P0072 2017 Chevrolet Silverado
- Faulty Ambient Air Temperature sensor.
- Damaged wiring or connectors in the sensor circuit.
- Corrosion or poor connections in the sensor circuit.
- Malfunctioning Engine Control Module (ECM).
- Environmental factors such as extreme temperatures affecting sensor performance.
Symptoms of P0072 2017 Chevrolet Silverado
- Incorrect temperature readings on the dashboard display.
- Inaccurate climate control system operation.
- Reduced fuel efficiency.
- Engine running rich or lean.
- Check Engine Light illuminated.
