Code B0158 2016 GMC Sierra Description
The B0158 code on a 2016 GMC Sierra indicates an issue with the ambient air temperature sensor circuit. The ambient air temperature sensor is responsible for measuring the temperature of the air outside the vehicle. This information is used by the engine control module (ECM) to adjust fuel delivery, ignition timing, and other engine functions to optimize performance and efficiency based on the outside temperature.
Common Causes of B0158 2016 GMC Sierra
- Faulty ambient air temperature sensor
- Damaged sensor wiring or connectors
- Corrosion or water damage to sensor components
- ECM issues affecting sensor communication
- Environmental factors such as extreme temperatures affecting sensor performance
Symptoms of B0158 2016 GMC Sierra
- Incorrect temperature readings on the dashboard display
- Engine running too rich or too lean
- Poor fuel efficiency
- Check engine light illuminated
- Inaccurate climate control system operation
How to Fix B0158 2016 GMC Sierra
- Use a scan tool to confirm the B0158 code and diagnose the specific issue with the ambient air temperature sensor circuit.
- Inspect the sensor, wiring, and connectors for any visible damage or corrosion. Replace any faulty components.
- Clear the code from the ECM memory and perform a road test to ensure the issue is resolved.
- If the problem persists, further diagnostic testing may be required to pinpoint the exact cause of the circuit malfunction.
- Reset the ECM and ensure proper communication between the ambient air temperature sensor and the engine control module.
Cost to Fix B0158 2016 GMC Sierra
The typical repair costs for addressing the B0158 code on a 2016 GMC Sierra can vary depending on the specific cause of the issue. In general, replacing the ambient air temperature sensor or repairing the sensor circuit could range from $100 to $300 for parts and labor. Additional diagnostic testing or ECM programming may incur extra charges. It's advisable to consult with a qualified mechanic or auto repair shop for an accurate cost estimate based on the vehicle's make and model, as well as any additional factors that may affect the repair process.
