P2052 Dodge Code - Reductant Injection Valve Circuit High Bank 2 Unit 1
Quick Answer
The P2052 diagnostic trouble code (DTC) for Dodge vehicles refers to an issue with the reductant injection valve circuit high on bank 2 unit 1. Common causes include Faulty Reductant Injection Valve: A malfunctioning reductant injection valve can cause high voltage in the circuit and trigger the P2052 code, Wiring or Connector Issues: Damaged wiring or a faulty connector in the circuit can disrupt the flow of electricity and lead to a high voltage condition, ECM Malfunction: A problem with the Engine Control Module (ECM) that controls the reductant injection system can also trigger the P2052 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 P2052 Dodge Description
The P2052 diagnostic trouble code (DTC) for Dodge vehicles refers to an issue with the reductant injection valve circuit high on bank 2 unit 1. This code typically indicates a problem with the reductant injection system, which is responsible for injecting a urea-based solution (commonly known as diesel exhaust fluid or DEF) into the exhaust stream to reduce harmful emissions.
Common Causes of P2052 Dodge
- Faulty Reductant Injection Valve: A malfunctioning reductant injection valve can cause high voltage in the circuit and trigger the P2052 code.
- Wiring or Connector Issues: Damaged wiring or a faulty connector in the circuit can disrupt the flow of electricity and lead to a high voltage condition.
- ECM Malfunction: A problem with the Engine Control Module (ECM) that controls the reductant injection system can also trigger the P2052 code.
- Reductant Injection Control Module Failure: If the control module for the reductant injection system fails, it can cause issues with the circuit and result in the code being set.
Symptoms of P2052 Dodge
- Check Engine Light: The most common symptom associated with the P2052 code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Power: The vehicle may go into a reduced power mode to prevent engine damage due to the high voltage condition in the reductant injection valve circuit.
- Poor Fuel Efficiency: A malfunctioning reductant injection system can lead to decreased fuel efficiency as the engine may not be operating at optimal levels.
- Failed Emissions Test: If the vehicle is due for an emissions inspection, the P2052 code can cause it to fail the test due to increased emissions.
How to Fix P2052 Dodge
- Diagnose the Issue: Use a scan tool to retrieve the P2052 code and perform a thorough inspection of the reductant injection system to identify the root cause of the problem.
- Test the Reductant Injection Valve: Check the reductant injection valve for proper operation and replace it if necessary.
- Inspect Wiring and Connectors: Examine the wiring and connectors in the circuit for any damage or corrosion, and repair or replace as needed.
- Check ECM and Control Module: Test the Engine Control Module (ECM) and the reductant injection control module for proper functioning, and replace if they are found to be faulty.
- Clear the Code: After completing the repairs, clear the P2052 code from the ECM's memory and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P2052 Dodge
The typical repair costs for addressing the P2052 code on a Dodge vehicle can vary depending on the specific cause of the issue and the cost of parts and labor. In general, the repair for this code can range from $200 to $500, including parts and labor. However, it's important to note that diagnosis time and labor rates at auto repair shops can fluctuate based on factors such as location, vehicle make and model, and engine type.
