P2044 Ford Code - Reductant Temperature Sensor Circuit Low
Quick Answer
The P2044 Ford diagnostic trouble code (DTC) specifically refers to the Reductant Temperature Sensor Circuit Low. Common causes include Faulty Reductant Temperature Sensor: The sensor itself may be malfunctioning, sending incorrect signals to the ECM, Wiring or Connector Issues: Corrosion, damage, or loose connections in the wiring harness or connectors associated with the reductant temperature sensor can cause the P2044 code to be triggered, SCR System Malfunction: Problems with other components of the SCR system, such as the DEF injector or SCR catalyst, can also lead to the P2044 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 P2044 Ford Description
The P2044 Ford diagnostic trouble code (DTC) specifically refers to the Reductant Temperature Sensor Circuit Low. In vehicles equipped with a Selective Catalytic Reduction (SCR) system, the reductant temperature sensor plays a crucial role in monitoring the temperature of the diesel exhaust fluid (DEF) or reductant solution. The reductant temperature sensor sends signals to the engine control module (ECM) to ensure the proper functioning of the SCR system, which helps reduce harmful emissions.
Common Causes of P2044 Ford
- Faulty Reductant Temperature Sensor: The sensor itself may be malfunctioning, sending incorrect signals to the ECM.
- Wiring or Connector Issues: Corrosion, damage, or loose connections in the wiring harness or connectors associated with the reductant temperature sensor can cause the P2044 code to be triggered.
- SCR System Malfunction: Problems with other components of the SCR system, such as the DEF injector or SCR catalyst, can also lead to the P2044 code.
- ECM Malfunction: In rare cases, a malfunctioning ECM may incorrectly interpret the signals from the reductant temperature sensor, triggering the P2044 code.
Symptoms of P2044 Ford
- Check Engine Light: The most common symptom associated with the P2044 code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Fuel Efficiency: A malfunctioning reductant temperature sensor can lead to decreased fuel efficiency as the ECM may not be able to optimize the SCR system's performance.
- Poor Performance: The vehicle may experience a decrease in overall performance, including reduced power and acceleration.
- Failed Emissions Test: If the P2044 code is not addressed, it may cause the vehicle to fail emissions testing due to increased emissions output.
How to Fix P2044 Ford
- Diagnose the Issue: Use a diagnostic scanner to retrieve the P2044 code and perform a thorough inspection of the reductant temperature sensor, wiring, connectors, and other related components.
- Replace the Reductant Temperature Sensor: If the sensor is found to be faulty, replace it with a new, OEM-quality sensor.
- Repair Wiring or Connectors: Address any wiring or connector issues by repairing or replacing damaged components.
- Check and Reset the ECM: After completing the repairs, clear the DTC and reset the ECM to ensure that the P2044 code does not reappear.
- Test Drive and Confirm Repair: Take the vehicle for a test drive to confirm that the issue has been resolved and that the check engine light does not reilluminate.
Cost to Fix P2044 Ford
The typical repair costs for addressing the P2044 Ford code can vary depending on the specific cause of the issue and the labor rates in your area. In general, the cost of replacing the reductant temperature sensor can range from $150 to $300, including parts and labor. Additional costs may apply if there are wiring or connector issues that need to be addressed. It is advisable to consult with a qualified mechanic or auto repair shop for a more accurate estimate based on your vehicle's make and model. Keep in mind that labor rates can vary significantly, so it's always best to compare prices from different repair shops before proceeding with the repairs.
