P0183 2017 GMC Sierra Code - Fuel Temperature Sensor Circuit High Voltage
Quick Answer
The P0183 diagnostic trouble code (DTC) for a 2017 GMC Sierra indicates that the fuel temperature sensor circuit is registering a higher than normal voltage. Common causes include Faulty Sensor: The fuel temperature sensor itself may be malfunctioning, leading to incorrect voltage readings, Wiring Issues: Damaged or corroded wiring connections to the sensor can cause high voltage readings, ECM Malfunction: A problem with the engine control module can also trigger this code. 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 2017 GMC Sierra Description
The P0183 diagnostic trouble code (DTC) for a 2017 GMC Sierra indicates that the fuel temperature sensor circuit is registering a higher than normal voltage. This sensor is responsible for measuring the temperature of the fuel in the tank, which is essential for the engine control module (ECM) to adjust the fuel mixture accordingly. When the voltage is too high, it can lead to inaccurate readings and potentially affect the vehicle's performance.
Common Causes of P0183 2017 GMC Sierra
- Faulty Sensor: The fuel temperature sensor itself may be malfunctioning, leading to incorrect voltage readings.
- Wiring Issues: Damaged or corroded wiring connections to the sensor can cause high voltage readings.
- ECM Malfunction: A problem with the engine control module can also trigger this code.
- Fuel Quality: Poor quality fuel or contamination in the fuel tank can affect the sensor's readings.
- Environmental Factors: Extreme temperatures or exposure to excessive heat can also impact the sensor's performance.
Symptoms of P0183 2017 GMC Sierra
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
- Poor Fuel Economy: A faulty fuel temperature sensor can cause the ECM to incorrectly adjust the fuel mixture, leading to decreased fuel efficiency.
- Engine Performance Issues: The vehicle may experience rough idling, stalling, or hesitation during acceleration.
- Difficulty Starting: The engine may have trouble starting or take longer than usual to turn over.
- Overheating: In extreme cases, the engine may overheat due to incorrect fuel mixture adjustments.
How to Fix P0183 2017 GMC Sierra
- Diagnose the Issue: Use a diagnostic scan tool to confirm the P0183 code and pinpoint the exact cause of the high voltage reading.
- Inspect the Sensor: Check the fuel temperature sensor for any visible signs of damage or corrosion. Replace if necessary.
- Check Wiring: Inspect the wiring harness connected to the sensor for any damage or loose connections. Repair or replace as needed.
- Test ECM: Ensure the engine control module is functioning properly by testing its communication with the sensor.
- Clear Codes: After completing the repair, clear the DTC and test drive the vehicle to verify that the issue has been resolved.
Cost to Fix P0183 2017 GMC Sierra
The typical repair cost for addressing a P0183 code on a 2017 GMC Sierra can range from $150 to $400, including parts and labor.
