Code B1024 2016 GMC Sierra Description
The B1024 diagnostic trouble code for a 2016 GMC Sierra specifically refers to an issue with the circuit board temperature sensor. This sensor is responsible for monitoring the temperature of the circuit board within the vehicle's electronic control module (ECM). The ECM is a crucial component that controls various systems in the vehicle, such as fuel injection, ignition timing, and emissions control.
Common Causes of B1024 2016 GMC Sierra
- Sensor Failure: The circuit board temperature sensor itself may have failed due to normal wear and tear or electrical issues.
- Wiring Damage: Damage to the wiring connecting the sensor to the ECM can cause communication issues and trigger this code.
- Loose Connections: Loose or corroded connections between the sensor and the ECM can lead to faulty temperature readings.
- ECM Malfunction: In rare cases, the issue may stem from a malfunction within the ECM itself, affecting its ability to interpret sensor data accurately.
Symptoms of B1024 2016 GMC Sierra
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Erratic Engine Performance: The vehicle may experience rough idling, hesitation, or poor acceleration due to incorrect temperature readings being sent to the ECM.
- Decreased Fuel Efficiency: A malfunctioning circuit board temperature sensor can lead to the ECM not optimizing fuel delivery, resulting in decreased fuel efficiency.
- Engine Stalling: In severe cases, the vehicle may stall unexpectedly due to the ECM not receiving accurate temperature data.
How to Fix B1024 2016 GMC Sierra
- Diagnostic Scan: Begin by using a diagnostic scanner to retrieve the specific trouble code and confirm that the circuit board temperature sensor is the root cause of the issue.
- Sensor Replacement: Replace the faulty circuit board temperature sensor with a new, OEM-quality sensor to ensure accurate temperature readings.
- Wiring Inspection: Thoroughly inspect the wiring harness connecting the sensor to the ECM for any damage or corrosion. Repair or replace any damaged wiring as needed.
- Connection Check: Ensure that the connections between the sensor and the ECM are secure and free of debris or corrosion. Clean and tighten connections if necessary.
- Clear Codes: After completing the repair, clear the diagnostic trouble codes from the vehicle's ECM memory to reset the system and ensure the issue has been resolved.
Cost to Fix B1024 2016 GMC Sierra
The typical repair costs for addressing a B1024 code related to the circuit board temperature sensor in a 2016 GMC Sierra can vary depending on the specific cause of the issue. On average, the cost of parts for a new sensor and potential wiring repairs can range from $50 to $200. Labor costs at auto repair shops typically range from $80 to $150 per hour. The total repair cost could therefore fall between $150 and $500, depending on the extent of the repair work needed. It's advisable to check with local auto repair shops for more accurate estimates based on your location and vehicle specifics.
