Code P0184 2017 GMC Sierra Description
The P0184 code for a 2017 GMC Sierra indicates a problem with the Fuel Temperature Sensor Circuit being erratic. The fuel temperature sensor is responsible for monitoring the temperature of the fuel in the fuel tank. This information is crucial for the engine control module (ECM) to adjust the air/fuel mixture for optimal combustion. When the sensor circuit is erratic, it means that the signal being sent to the ECM is inconsistent or fluctuating, which can lead to various issues with the vehicle's performance.
Common Causes of P0184 2017 GMC Sierra
- Faulty Fuel Temperature Sensor: The sensor itself may be malfunctioning, providing inconsistent readings to the ECM.
- Wiring Issues: Damaged or corroded wiring connecting the sensor to the ECM can result in erratic readings.
- ECM Malfunction: A problem with the engine control module's ability to interpret the sensor signals can cause the circuit to be erratic.
- Poor Electrical Connection: Loose or poor electrical connections can disrupt the sensor circuit, leading to erratic readings.
Symptoms of P0184 2017 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.
- Poor Fuel Efficiency: Erratic fuel temperature sensor readings can lead to incorrect fuel mixture adjustments, resulting in decreased fuel efficiency.
- Rough Idling: Fluctuating fuel temperature readings can cause the engine to idle roughly or inconsistently.
- Engine Misfires: In severe cases, an erratic fuel temperature sensor circuit can lead to engine misfires as a result of incorrect air/fuel mixture.
How to Fix P0184 2017 GMC Sierra
- Diagnose the Issue: Use a diagnostic scanner to retrieve the trouble code and further investigate the fuel temperature sensor circuit.
- Inspect Sensor and Wiring: Check the fuel temperature sensor for any visible damage or signs of malfunction. Inspect the wiring for any issues.
- Replace Sensor or Repair Wiring: If the sensor is faulty, replace it with a new one. If wiring issues are detected, repair or replace the damaged wiring.
- Clear Codes: After making the necessary repairs, clear the trouble codes 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 P0184 2017 GMC Sierra
The cost of repairing a fuel temperature sensor circuit erratic issue can vary depending on the extent of the problem and the specific components that need to be replaced. On average, the cost of replacing a fuel temperature sensor can range from $100 to $200, while the labor costs for diagnosis and repair can range from $100 to $300. Overall, the total repair cost for this issue can be estimated to be between $200 and $500. It's important to note that actual costs may vary based on the location of the repair shop, the vehicle's make and model, and any additional repairs that may be needed.
