Code P20FD Dodge Description
The P20FD diagnostic trouble code (DTC) for Dodge vehicles refers to a problem with the Reductant Pump 2 Control Circuit being detected as low. The reductant pump is a crucial component of the Selective Catalytic Reduction (SCR) system, which is responsible for reducing harmful emissions in diesel engines. The reductant pump is tasked with supplying the necessary Diesel Exhaust Fluid (DEF) to the SCR system to facilitate the chemical reaction that converts harmful nitrogen oxides (NOx) into harmless nitrogen and water vapor.
Common Causes of P20FD Dodge
- Faulty Reductant Pump: The most common cause of this code is a malfunctioning Reductant Pump 2 itself.
- Wiring Issues: Problems with the wiring harness or connectors associated with the Reductant Pump 2 control circuit can trigger this code.
- Defective Control Module: A faulty control module responsible for managing the Reductant Pump 2 operation can also cause this issue.
- Low DEF Fluid Level: Insufficient DEF fluid in the tank can lead to issues with the reductant pump's operation.
Symptoms of P20FD 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 Fuel Efficiency: A malfunctioning reductant pump can lead to inefficient DEF delivery, resulting in decreased fuel efficiency.
- Poor Engine Performance: The vehicle may experience a decrease in engine performance, including rough idling or hesitation during acceleration.
- Failed Emissions Test: If the issue is not resolved, the vehicle may fail emissions tests due to increased NOx emissions.
How to Fix P20FD Dodge
- Diagnose the Issue: Use a diagnostic scanner to retrieve the specific DTC and pinpoint the exact cause of the problem.
- Inspect Wiring and Connectors: Check the wiring harness and connectors for any signs of damage or corrosion and repair or replace as needed.
- Test Reductant Pump 2: Test the functionality of the Reductant Pump 2 to determine if it is operating correctly. Replace if necessary.
- Check DEF Fluid Level: Ensure that the DEF fluid level is adequate and refill if necessary.
- Clear Codes and Test Drive: Clear the DTC from the vehicle's computer, then test drive the vehicle to ensure that the issue has been resolved.
Cost to Fix P20FD Dodge
The typical repair costs for addressing a P20FD code related to the Reductant Pump 2 Control Circuit Low can vary depending on the specific cause of the issue. In general, the cost of replacing a faulty Reductant Pump 2 can range from $200 to $500, including parts and labor.

Frequently Asked Questions about P20FD Dodge Code
1. What does the OBDII code P20FD mean on a Dodge vehicle?
P20FD indicates a problem with the Reductant Pump 2 Control Circuit, specifically that the circuit is experiencing low voltage or an electrical fault.
2. What are the common symptoms of the P20FD code?
Symptoms may include the Check Engine Light or DEF warning light illuminating, reduced engine performance, and possible issues with the selective catalytic reduction (SCR) system.
3. What causes the P20FD code to appear?
Common causes include a faulty reductant pump, damaged wiring or connectors in the pump circuit, a failed control module, or low voltage issues in the vehicle's electrical system.
4. Can I continue driving with a P20FD code?
Driving with a P20FD code is not recommended as it may lead to reduced engine power or failure to meet emissions standards, potentially causing further damage to the SCR system.
5. How can I diagnose the P20FD code?
Start by inspecting the wiring and connectors for damage or corrosion. Use a multimeter to check for proper voltage and continuity in the reductant pump control circuit.
6. How do I fix the P20FD code on my Dodge?
Repairs may include replacing the reductant pump, repairing or replacing damaged wiring or connectors, or updating/replacing the control module if needed.
7. Is the P20FD code related to the DEF system?
Yes, the P20FD code is directly related to the Diesel Exhaust Fluid (DEF) system since the reductant pump is responsible for delivering DEF to the SCR system.
8. How much does it cost to repair a P20FD code?
Repair costs vary but may range from $200 to $1000, depending on whether you need to replace the reductant pump or address wiring and module issues.
9. Can a low DEF level cause the P20FD code?
A low DEF level usually triggers a different code, but ensuring the DEF tank is adequately filled is a good first step in troubleshooting.
10. Will clearing the P20FD code solve the issue?
Clearing the code without addressing the underlying problem will only result in the code returning. Proper diagnosis and repair are necessary.
