Code P0653 2016 Chevrolet Silverado Description
The P0653 diagnostic trouble code (DTC) for a 2016 Chevrolet Silverado indicates a problem with the 5 Volt Reference 2 Circuit High Voltage. This code is triggered when the Engine Control Module (ECM) detects that the voltage on the 5-volt reference circuit is higher than normal. The 5-volt reference circuit is used by various sensors in the vehicle to provide accurate readings to the ECM. When this circuit has high voltage, it can cause issues with sensor readings and affect the overall performance of the vehicle.
Common Causes of P0653 2016 Chevrolet Silverado
- Short Circuit: A short circuit in the wiring harness connected to the 5-volt reference circuit can cause high voltage readings.
- Faulty Sensor: A malfunctioning sensor that is connected to the 5-volt reference circuit can also trigger this code.
- ECM Malfunction: A problem with the Engine Control Module (ECM) can lead to high voltage on the 5-volt reference circuit.
- Corrosion: Corrosion or damage to the wiring or connectors in the 5-volt reference circuit can cause electrical issues.
Symptoms of P0653 2016 Chevrolet Silverado
- Check Engine Light: The most common symptom associated with the P0653 code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Erratic Engine Performance: The vehicle may experience rough idling, stalling, or hesitation during acceleration due to incorrect sensor readings.
- Poor Fuel Efficiency: High voltage on the 5-volt reference circuit can lead to inaccurate fuel mixture calculations, resulting in decreased fuel efficiency.
- Emission Issues: The vehicle may fail emissions tests due to incorrect sensor readings caused by the high voltage on the reference circuit.
How to Fix P0653 2016 Chevrolet Silverado
- Diagnose the Issue: Use a diagnostic scanner to retrieve the DTC and perform a thorough inspection of the wiring harness, sensors, and ECM to identify the root cause of the high voltage on the 5-volt reference circuit.
- Repair or Replace Wiring: If a short circuit or corrosion is found in the wiring harness, repair or replace the damaged wires to ensure proper electrical connections.
- Test Sensors: Check the sensors connected to the 5-volt reference circuit for proper operation. Replace any faulty sensors that are causing the high voltage readings.
- Check ECM: Test the Engine Control Module (ECM) for malfunctions. If necessary, reprogram or replace the ECM to resolve the issue.
- Clear DTC and Test Drive: After completing the repairs, clear the DTC from the ECM memory and take the vehicle for a test drive to ensure that the issue has been resolved.
Cost to Fix P0653 2016 Chevrolet Silverado
The typical repair costs for addressing the P0653 code on a 2016 Chevrolet Silverado can range from $200 to $500, including parts and labor. However, it's important to note that specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. Most auto repair shops charge between $80 and $150 per hour for labor, but rates may be higher in metropolitan areas or at dealerships, while independent shops often charge less. It is recommended to inquire about local rates to get a more accurate estimate for this repair.
