P2054 Dodge Code - Reductant Injection Valve Circuit Low Bank 1 Unit 2
Quick Answer
The P2054 diagnostic trouble code for Dodge vehicles refers to an issue with the Reductant Injection Valve Circuit Low Bank 1 Unit 2. Common causes include Faulty Reductant Injection Valve: The most common cause of this code is a malfunctioning reductant injection valve that is not operating within the specified voltage range, Wiring Issues: Damaged or corroded wiring connections related to the reductant injection valve circuit can also trigger this code, ECM Malfunction: A problem with the engine control module (ECM) that controls the reductant injection system could result in a low voltage condition. 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 P2054 Dodge Description
The P2054 diagnostic trouble code for Dodge vehicles refers to an issue with the Reductant Injection Valve Circuit Low Bank 1 Unit 2. This code indicates a problem with the reductant injection system, which is responsible for controlling emissions in diesel vehicles equipped with selective catalytic reduction (SCR) systems. The reductant injection valve is a crucial component that helps regulate the flow of diesel exhaust fluid (DEF) into the exhaust stream to reduce harmful emissions.
Common Causes of P2054 Dodge
- Faulty Reductant Injection Valve: The most common cause of this code is a malfunctioning reductant injection valve that is not operating within the specified voltage range.
- Wiring Issues: Damaged or corroded wiring connections related to the reductant injection valve circuit can also trigger this code.
- ECM Malfunction: A problem with the engine control module (ECM) that controls the reductant injection system could result in a low voltage condition.
- Poor Electrical Ground: Inadequate grounding of the reductant injection valve circuit can lead to voltage irregularities and trigger this code.
- Sensor Malfunction: A faulty sensor within the reductant injection system may also cause the ECM to detect a low voltage condition and set the P2054 code.
Symptoms of P2054 Dodge
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Performance: Drivers may experience a decrease in engine performance, including reduced power and acceleration.
- Poor Fuel Efficiency: A malfunctioning reductant injection valve can lead to decreased fuel efficiency, resulting in more frequent refueling.
- Increased Emissions: The vehicle may produce higher levels of emissions than usual, potentially leading to environmental concerns.
- Rough Idle: In some cases, drivers may notice a rough or unstable idle when the reductant injection valve circuit is malfunctioning.
How to Fix P2054 Dodge
- Diagnose the Issue: Begin by using a diagnostic scanner to retrieve the specific trouble code and identify the exact cause of the low voltage condition.
- Inspect Wiring and Connections: Check the wiring harness and connectors related to the reductant injection valve circuit for any damage, corrosion, or loose connections.
- Test Reductant Injection Valve: Verify the functionality of the reductant injection valve by testing its voltage output and operation under different conditions.
- Replace Faulty Components: If a faulty reductant injection valve, wiring, or sensor is identified, replace the defective component with a new, OEM-quality part.
- Clear Error Codes: After completing the repairs, clear the error codes from the ECM's memory using a diagnostic scanner to reset the check engine light and monitor the system for any recurring issues.
Cost to Fix P2054 Dodge
The typical repair costs for addressing a P2054 code on a Dodge vehicle can vary depending on the specific cause of the issue and the parts and labor required for the repair. In general, replacing a faulty reductant injection valve or repairing wiring connections may cost between $200 and $500, including parts and labor. However, additional diagnostic time and labor rates at auto repair shops can impact the overall cost. It's recommended to contact local repair facilities for more accurate estimates based on the vehicle's make and model, as well as the technician's hourly rates.
