P0183 2016 GMC Sierra Code - Fuel Temperature Sensor Circuit High Voltage
Quick Answer
The P0183 diagnostic trouble code (DTC) for a 2016 GMC Sierra indicates a problem with the Fuel Temperature Sensor Circuit High Voltage. Common causes include Faulty Fuel Temperature Sensor: The sensor itself may be malfunctioning, providing incorrect readings to the ECM, Damaged Wiring or Connectors: Any damage to the wiring or connectors in the fuel temperature sensor circuit can disrupt the signal and trigger the P0183 code, ECM Malfunction: Issues with the engine control module can also lead to high voltage signals from the fuel temperature sensor circuit. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0183 2016 GMC Sierra Description
The P0183 diagnostic trouble code (DTC) for a 2016 GMC Sierra indicates a problem with the Fuel Temperature Sensor Circuit High Voltage. This sensor is responsible for measuring the temperature of the fuel in the fuel tank. The sensor sends this information to the engine control module (ECM) to help optimize fuel delivery and combustion efficiency. When the ECM detects a high voltage signal from the fuel temperature sensor circuit, it triggers the P0183 code.
Common Causes of P0183 2016 GMC Sierra
- Faulty Fuel Temperature Sensor: The sensor itself may be malfunctioning, providing incorrect readings to the ECM.
- Damaged Wiring or Connectors: Any damage to the wiring or connectors in the fuel temperature sensor circuit can disrupt the signal and trigger the P0183 code.
- ECM Malfunction: Issues with the engine control module can also lead to high voltage signals from the fuel temperature sensor circuit.
- Corrosion: Corrosion or contamination in the sensor or circuit can interfere with proper signal transmission.
- Environmental Factors: Extreme temperatures or exposure to moisture can also contribute to sensor malfunction.
Symptoms of P0183 2016 GMC Sierra
- Check Engine Light: The most common symptom associated with the P0183 code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Fuel Efficiency: A malfunctioning fuel temperature sensor can lead to inaccurate fuel mixture calculations, resulting in decreased fuel efficiency.
- Engine Performance Issues: The vehicle may experience rough idling, hesitation, or a lack of power due to incorrect fuel delivery.
- Engine Misfires: In severe cases, the P0183 code can lead to engine misfires, which can cause further damage if not addressed promptly.
How to Fix P0183 2016 GMC Sierra
- Diagnose the Issue: Use a diagnostic scanner to retrieve the P0183 code and perform further testing to pinpoint the exact cause of the problem.
- Inspect Wiring and Connectors: Check the wiring and connectors in the fuel temperature sensor circuit for any damage or corrosion. Repair or replace as necessary.
- Test the Fuel Temperature Sensor: Test the fuel temperature sensor itself to determine if it is providing accurate readings. Replace the sensor if found to be faulty.
- Clear the Code: After making the necessary repairs, clear the P0183 code from the ECM's memory using the diagnostic scanner.
- Test Drive: Take the vehicle for a test drive to ensure that the issue has been resolved and that the check engine light does not reappear.
Cost to Fix P0183 2016 GMC Sierra
The typical repair costs for addressing a P0183 code in a 2016 GMC Sierra can range from $150 to $400, depending on the specific cause of the issue and the cost of parts and labor. This estimate includes the cost of a new fuel temperature sensor, potential wiring repairs, and diagnostic testing. It's important to note that the actual repair costs can vary based on factors such as the location of the repair shop, the make and model of the vehicle, and the extent of the repairs needed. Additionally, labor rates at auto repair shops can range from $80 to $150 per hour, with rates potentially higher at dealerships or in metropolitan areas. To obtain a more accurate estimate, it is recommended to consult with local auto repair shops.
