P0182 2018 GMC Sierra Code - Fuel Temperature Sensor Circuit Low Voltage
Quick Answer
The P0182 diagnostic trouble code (DTC) for a 2018 GMC Sierra indicates a problem with the Fuel Temperature Sensor Circuit, specifically low voltage. Common causes include Faulty Fuel Temperature Sensor: The sensor itself may be defective, leading to inaccurate readings and triggering the code, Wiring Issues: Damaged or corroded wiring in the sensor circuit can cause low voltage and disrupt the sensor's operation, Poor Electrical Connection: Loose or poor electrical connections at the sensor or ECM can result in low voltage readings. 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 P0182 2018 GMC Sierra Description
The P0182 diagnostic trouble code (DTC) for a 2018 GMC Sierra indicates a problem with the Fuel Temperature Sensor Circuit, specifically low voltage. The fuel temperature sensor is a crucial component in the vehicle's fuel system, as it measures the temperature of the fuel in the tank. This information is used by the engine control module (ECM) to adjust fuel delivery and optimize engine performance. When the sensor detects low voltage, it means that there is an issue with the circuit that may lead to inaccurate temperature readings or a complete failure of the sensor.
Common Causes of P0182 2018 GMC Sierra
- Faulty Fuel Temperature Sensor: The sensor itself may be defective, leading to inaccurate readings and triggering the code.
- Wiring Issues: Damaged or corroded wiring in the sensor circuit can cause low voltage and disrupt the sensor's operation.
- Poor Electrical Connection: Loose or poor electrical connections at the sensor or ECM can result in low voltage readings.
- ECM Malfunction: A malfunctioning ECM may not be properly interpreting the sensor data, causing the low voltage code.
Symptoms of P0182 2018 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 Economy: A malfunctioning fuel temperature sensor can lead to incorrect fuel delivery, resulting in decreased fuel efficiency.
- Engine Stalling: In severe cases, the engine may stall or have difficulty starting due to inaccurate fuel temperature readings.
- Rough Idle: The engine may exhibit rough idling or hesitation during acceleration as a result of the sensor issue.
How to Fix P0182 2018 GMC Sierra
- Diagnose the Issue: Use a scan tool to retrieve the DTC and perform a thorough inspection of the fuel temperature sensor circuit to identify the root cause of the problem.
- Replace the Fuel Temperature Sensor: If the sensor is found to be faulty, replace it with a new one to ensure accurate temperature readings.
- Check Wiring and Connections: Inspect the wiring and connectors in the sensor circuit for any damage or corrosion, repairing or replacing as needed.
- Clear DTC and Test Drive: Clear the DTC from the ECM memory, then test drive the vehicle to ensure that the issue has been resolved and the code does not return.
Cost to Fix P0182 2018 GMC Sierra
The typical repair costs for addressing a P0182 code on a 2018 GMC Sierra can vary depending on the specific cause of the issue. In general, the cost of a new fuel temperature sensor can range from $50 to $150, while labor costs for diagnosis and repair may range from $100 to $300. Overall, the total repair cost could be between $150 and $450, including parts and labor. It is important to note that these estimates are approximate, and actual costs may vary based on factors such as location, labor rates, and additional repairs that may be required. It is recommended to consult with a qualified mechanic or auto repair shop for a more accurate cost estimate.
