Code P0070 2015 GMC Sierra Description
The P0070 diagnostic trouble code (DTC) for a 2015 GMC Sierra refers to an issue with the Ambient Air Temperature (AAT) sensor circuit. The AAT sensor is responsible for monitoring the temperature of the air outside the vehicle. This information is crucial for various systems in the vehicle, including the engine control module (ECM), climate control system, and transmission control module (TCM). The AAT sensor helps the ECM adjust fuel delivery, ignition timing, and emissions control strategies based on the outside air temperature.
Common Causes of P0070 2015 GMC Sierra
- Faulty Ambient Air Temperature sensor
- Damaged wiring or connectors in the AAT sensor circuit
- Corrosion or contamination in the sensor connector
- ECM software issue
- Environmental factors such as extreme temperatures affecting sensor performance
Symptoms of P0070 2015 GMC Sierra
- Incorrect temperature readings on the dashboard
- Poor fuel economy
- Engine running rough or stalling
- Climate control system not functioning correctly
- Check Engine Light illuminated
How to Fix P0070 2015 GMC Sierra
- Begin by locating the Ambient Air Temperature sensor, usually located behind the front bumper or near the grille.
- 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 readings.
- If the sensor is faulty, replace it with a new OEM part.
- Clear the DTC with a scan tool and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0070 2015 GMC Sierra
The cost of repairing the Ambient Air Temperature sensor circuit can vary depending on the specific cause of the issue. In general, the price of a new AAT sensor ranges from $20 to $50, while labor costs can range from $80 to $150 per hour. The total repair cost, including parts and labor, may fall between $100 and $300.
