P2044 Dodge Code - Reductant Temperature Sensor Circuit Low
Quick Answer
The P2044 diagnostic trouble code (DTC) for Dodge vehicles refers to the Reductant Temperature Sensor Circuit Low. Common causes include Faulty Reductant Temperature Sensor: The most common cause of the P2044 code is a malfunctioning reductant temperature sensor itself, Wiring Issues: Corrosion, damage, or loose connections in the wiring harness connected to the reductant temperature sensor can also trigger this code, ECM Malfunction: A problem with the engine control module (ECM) that interprets the sensor's signals incorrectly could 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 Dodge Description
The P2044 diagnostic trouble code (DTC) for Dodge vehicles refers to the Reductant Temperature Sensor Circuit Low. This code indicates that the engine control module (ECM) has detected a lower than expected voltage signal from the reductant temperature sensor. The reductant temperature sensor is a crucial component of the selective catalytic reduction (SCR) system, which helps reduce harmful emissions in diesel engines by injecting a urea-based solution (DEF) into the exhaust stream.
Common Causes of P2044 Dodge
- Faulty Reductant Temperature Sensor: The most common cause of the P2044 code is a malfunctioning reductant temperature sensor itself.
- Wiring Issues: Corrosion, damage, or loose connections in the wiring harness connected to the reductant temperature sensor can also trigger this code.
- ECM Malfunction: A problem with the engine control module (ECM) that interprets the sensor's signals incorrectly could lead to the P2044 code.
- Exhaust System Leaks: Leaks in the exhaust system can affect the temperature readings of the reductant temperature sensor, causing it to read lower than expected values.
Symptoms of P2044 Dodge
- 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 Power Mode: The vehicle may go into a reduced power mode to protect the engine from potential damage caused by the malfunctioning reductant temperature sensor.
- Decreased Fuel Efficiency: A faulty reductant temperature sensor can lead to decreased fuel efficiency as the ECM may not be able to optimize the DEF injection rate.
- Poor Performance: The vehicle may experience reduced engine performance, including sluggish acceleration and overall drivability issues.
How to Fix P2044 Dodge
- Diagnose the Issue: Use a diagnostic scanner to retrieve the DTCs and pinpoint the specific cause of the P2044 code related to the reductant temperature sensor circuit.
- Inspect Wiring and Connections: Check the wiring harness and connections for any signs of damage, corrosion, or loose connections. Repair or replace any faulty wiring as needed.
- Test the Reductant Temperature Sensor: Test the reductant temperature sensor using a multimeter to ensure it is functioning correctly. Replace the sensor if it is faulty.
- Clear DTCs and Test Drive: Clear the DTCs from the ECM memory and test drive the vehicle to ensure the issue has been resolved and the check engine light does not reappear.
- Verify Repair: Use a diagnostic scanner to verify that the P2044 code has been successfully cleared and that the reductant temperature sensor is providing accurate readings to the ECM.
Cost to Fix P2044 Dodge
The typical repair costs for addressing the P2044 code related to the reductant temperature sensor circuit low can vary depending on the specific cause of the issue and the vehicle's make and model. In general, the cost of replacing a faulty reductant temperature sensor can range from $100 to $300, including parts and labor. However, if the issue is related to wiring repairs or ECM malfunction, the costs may be higher.
