Code P0073 2016 Chevrolet Silverado Description
The P0073 diagnostic trouble code (DTC) for a 2016 Chevrolet Silverado indicates a problem with the Ambient Air Temperature (AAT) sensor circuit registering high voltage. The AAT sensor is responsible for measuring the temperature of the air outside the vehicle and providing this information to the engine control module (ECM). This data is crucial for the ECM to adjust fuel delivery, ignition timing, and other engine parameters to optimize performance and fuel efficiency based on the external temperature.
Common Causes of P0073 2016 Chevrolet Silverado
- Faulty Ambient Air Temperature sensor
- Wiring issues or shorts in the AAT sensor circuit
- Corrosion or poor connections in the sensor wiring
- ECM software or hardware issues
- Environmental factors affecting the sensor's readings (e.g., heat from the engine)
Symptoms of P0073 2016 Chevrolet Silverado
- Decreased fuel efficiency
- Rough idling or stalling
- Hesitation during acceleration
- Check Engine Light illuminated
How to Fix P0073 2016 Chevrolet Silverado
- Begin by locating the Ambient Air Temperature sensor, typically located near the front grille or bumper.
- Inspect the sensor and its wiring for any visible damage, corrosion, or loose connections.
- Test the sensor using a multimeter to check for proper resistance values and voltage output.
- If the sensor is faulty, replace it with a new OEM or high-quality aftermarket sensor.
- Clear the DTC using a scan tool and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0073 2016 Chevrolet Silverado
