P205E Dodge Code - Reductant Tank Temperature Sensor Circuit Intermittent/Erratic
Quick Answer
The P205E diagnostic trouble code (DTC) for Dodge vehicles indicates an issue with the Reductant Tank Temperature Sensor Circuit being intermittent or erratic. Common causes include Faulty Reductant Tank Temperature Sensor: The sensor itself may be malfunctioning, leading to intermittent or erratic readings, Wiring or Connector Issues: Damage to the wiring or connectors in the sensor circuit can disrupt the communication between the sensor and the ECM, ECM Malfunction: A malfunctioning ECM may not be able to properly interpret the signals from the sensor, causing the intermittent or erratic 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 P205E Dodge Description
The P205E diagnostic trouble code (DTC) for Dodge vehicles indicates an issue with the Reductant Tank Temperature Sensor Circuit being intermittent or erratic. The reductant tank temperature sensor is a critical component of the Selective Catalytic Reduction (SCR) system, which helps reduce harmful emissions from the vehicle. This sensor is responsible for monitoring the temperature of the reductant (usually a urea-based solution) in the tank to ensure optimal operation of the SCR system.
Common Causes of P205E Dodge
- Faulty Reductant Tank Temperature Sensor: The sensor itself may be malfunctioning, leading to intermittent or erratic readings.
- Wiring or Connector Issues: Damage to the wiring or connectors in the sensor circuit can disrupt the communication between the sensor and the ECM.
- ECM Malfunction: A malfunctioning ECM may not be able to properly interpret the signals from the sensor, causing the intermittent or erratic readings.
- Environmental Factors: Extreme temperatures or exposure to contaminants can also affect the performance of the reductant tank temperature sensor.
Symptoms of P205E Dodge
- Check Engine Light: The most common symptom associated with the P205E code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Reduced Fuel Efficiency: A faulty reductant tank temperature sensor can lead to suboptimal operation of the SCR system, resulting in decreased fuel efficiency.
- Difficulty Starting: In some cases, the vehicle may experience difficulty starting or rough idling due to the inaccurate temperature readings from the sensor.
- Failed Emissions Test: If the P205E code is not addressed promptly, it can lead to increased emissions and potentially cause the vehicle to fail emissions tests.
How to Fix P205E Dodge
- Diagnose the Issue: Use a diagnostic scanner to retrieve the P205E code and perform a thorough inspection of the reductant tank temperature sensor and its circuit.
- Replace the Reductant Tank Temperature Sensor: If the sensor is found to be faulty, replace it with a new, OEM-quality sensor.
- Check Wiring and Connectors: Inspect the wiring and connectors in the sensor circuit for any damage or corrosion, and repair or replace as necessary.
- Reset the Check Engine Light: After completing the repairs, clear the code and reset the Check Engine Light using a 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 P205E Dodge
The typical repair costs for addressing the P205E code can vary depending on the specific cause of the issue and the labor rates at the auto repair shop. In general, replacing the reductant tank temperature sensor can cost between $150 and $300, while diagnosing and repairing wiring or connector issues may add to the total cost. Including parts and labor, the total repair cost for this issue could range from $200 to $500. It is important to note that the specific diagnosis time and labor rates can vary based on factors such as location, vehicle make and model, and engine type. It is advisable to check with local auto repair shops for more accurate estimates.
