P2055 Dodge Code - Reductant Injection Valve Circuit High Bank 1 Unit 2
Quick Answer
The P2055 diagnostic trouble code for Dodge vehicles indicates a problem with the Reductant Injection Valve Circuit High on Bank 1 Unit 2. Common causes include Faulty Reductant Injection Valve: The valve itself may be malfunctioning, causing the high voltage condition in the circuit, Wiring Issues: Corrosion, damage, or poor connections in the wiring harness can disrupt the flow of electrical signals to the Reductant Injection Valve, ECM Malfunction: A malfunction in the Engine Control Module could be sending incorrect signals to the Reductant Injection Valve. 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 P2055 Dodge Description
The P2055 diagnostic trouble code for Dodge vehicles indicates a problem with the Reductant Injection Valve Circuit High on Bank 1 Unit 2. This code is specifically related to the Selective Catalytic Reduction (SCR) system, which is responsible for reducing harmful emissions by injecting a urea-based solution (DEF - Diesel Exhaust Fluid) into the exhaust stream. The Reductant Injection Valve controls the flow of DEF into the exhaust system to aid in the conversion of nitrogen oxides into harmless nitrogen and water vapor.
Common Causes of P2055 Dodge
- Faulty Reductant Injection Valve: The valve itself may be malfunctioning, causing the high voltage condition in the circuit.
- Wiring Issues: Corrosion, damage, or poor connections in the wiring harness can disrupt the flow of electrical signals to the Reductant Injection Valve.
- ECM Malfunction: A malfunction in the Engine Control Module could be sending incorrect signals to the Reductant Injection Valve.
- Defective Sensor: A faulty sensor that monitors the Reductant Injection Valve circuit could be providing inaccurate readings, triggering the code.
Symptoms of P2055 Dodge
- Check Engine Light: The most common symptom associated with this code is the illumination of the Check Engine Light on the dashboard.
- Reduced Power: The vehicle may experience a decrease in power and acceleration due to the compromised efficiency of the SCR system.
- Poor Fuel Efficiency: An increase in fuel consumption may occur as a result of the system not functioning optimally.
- Increased Emissions: The vehicle may produce higher levels of harmful emissions, potentially leading to environmental concerns.
How to Fix P2055 Dodge
- Diagnose the Issue: Use a diagnostic scanner to retrieve the trouble code and pinpoint the exact cause of the problem.
- Inspect Wiring and Connections: Check the wiring harness for any signs of damage, corrosion, or poor connections, and repair or replace as needed.
- Test Reductant Injection Valve: Test the functionality of the Reductant Injection Valve to determine if it is faulty and replace if necessary.
- Check ECM: Inspect the Engine Control Module for any signs of malfunction and reprogram or replace if required.
- Clear Codes and Test Drive: After completing the repairs, clear the diagnostic trouble codes, and take the vehicle for a test drive to ensure the issue has been resolved.
Cost to Fix P2055 Dodge
The typical repair costs for addressing a P2055 code on a Dodge vehicle can vary depending on the specific cause of the issue. In general, the cost of replacing a Reductant Injection Valve can range from $200 to $500, while addressing wiring issues or ECM malfunctions may add to the total repair bill. Including parts and labor, the total cost could range from $300 to $800 or more. It's important to note that diagnostic time and labor rates at auto repair shops can vary, so it's recommended to check with local establishments for a more accurate estimate.
