Code P20FA RAM Description
The P20FA diagnostic trouble code (DTC) specifically refers to the Reductant Pump 2 Control Circuit Open. This code is typically found in vehicles equipped with a diesel engine and an emissions control system that utilizes a selective catalytic reduction (SCR) system. The reductant pump is responsible for delivering diesel exhaust fluid (DEF) to the SCR system, which reduces harmful nitrogen oxide emissions into nitrogen and water vapor.
Common Causes of P20FA RAM
- Faulty reductant pump 2
- Wiring or connector issues in the control circuit
- Corrosion or damage to electrical components
- Software or programming issues
- Environmental factors such as water exposure or debris accumulation
Symptoms of P20FA RAM
- Check engine light illuminated
- Reduced fuel efficiency
- Engine performance issues
- Failed emissions test
- Increased nitrogen oxide emissions
How to Fix P20FA RAM
- Begin by conducting a visual inspection of the reductant pump 2 and its wiring harness to check for any obvious signs of damage or corrosion.
- Use a multimeter to test the continuity and resistance of the control circuit to identify any open circuits or faulty connections.
- Replace the reductant pump 2 if it is determined to be faulty, ensuring that the new pump is properly installed and connected.
- Clear the DTC from the vehicle's onboard computer using a diagnostic scan tool and verify that the check engine light is no longer illuminated.
- Test drive the vehicle to ensure that the repair was successful and that the symptoms associated with the P20FA code have been resolved.
Cost to Fix P20FA RAM
The cost of repairing a P20FA code related to the Reductant Pump 2 Control Circuit Open can vary depending on the make and model of the vehicle, the location of the repair shop, and whether genuine OEM parts are used. On average, the cost of parts for a reductant pump replacement can range from $200 to $500, while labor costs can range from $150 to $300. Overall, the total cost of repairing this issue can be estimated to be between $350 and $800. It is advisable to consult with a local auto repair shop for a more accurate cost estimate based on the specific circumstances of the vehicle in question.

Frequently Asked Questions about P20FA RAM Code
1. What does the OBDII code P20FA mean on a RAM vehicle?
P20FA indicates an issue with the Reductant Pump 2 Control Circuit, specifically an open circuit, which affects the diesel exhaust fluid (DEF) system.
2. What are the common symptoms of a P20FA code?
Symptoms include the check engine light turning on, DEF-related warning messages, poor engine performance, or the vehicle entering limp mode.
3. What causes the P20FA code to appear?
Common causes include faulty reductant pump wiring, a malfunctioning reductant pump, damaged electrical connectors, or a blown fuse in the control circuit.
4. Can I drive my vehicle with a P20FA code?
While the vehicle may still be drivable, long-term operation with this code can lead to reduced performance and emissions compliance issues. It’s best to address it promptly.
5. How can I diagnose a P20FA code?
Start by inspecting the wiring and connectors for damage, checking the reductant pump for proper operation, and testing the circuit for continuity and voltage.
6. Does the P20FA code mean the reductant pump needs replacement?
Not necessarily. The issue could be due to a wiring problem, connector issue, or another electrical fault rather than the pump itself.
7. What tools are needed to troubleshoot a P20FA code?
You’ll need an OBDII scanner, a multimeter for electrical testing, and possibly a wiring diagram for your vehicle’s DEF system.
8. How much does it cost to fix a P20FA code?
Repair costs can vary depending on the cause. Wiring repairs may cost less than $100, while reductant pump replacement could range from $500 to $1,000 or more.
9. Is P20FA a common issue on RAM trucks?
This code is not extremely common but can occur in vehicles with a DEF system, particularly if wiring or pump components degrade over time.
10. How can I prevent the P20FA code from recurring?
Regular maintenance of the DEF system, including inspecting wiring and connectors for damage, can help prevent this code from reappearing.
