Code P20FC Dodge Description
The P20FC diagnostic trouble code (DTC) for Dodge vehicles specifically pertains to the Reductant Pump 2 Control Circuit Low. This code indicates that there is a problem with the control circuit of the reductant pump 2, which is a crucial component of the vehicle's Selective Catalytic Reduction (SCR) system. The SCR system is responsible for reducing harmful emissions by injecting a urea-based reductant into the exhaust stream, where it reacts with nitrogen oxides (NOx) to convert them into nitrogen and water vapor.
Common Causes of P20FC Dodge
- Faulty Reductant Pump 2: The most common cause of this code is a malfunctioning reductant pump 2, which can result from internal failures or electrical issues.
- Wiring Issues: Problems with the wiring harness or connectors associated with the reductant pump 2 control circuit can also trigger this code.
- Defective Sensors: Faulty NOx sensors or other related sensors can cause inaccuracies in the control circuit, leading to the code being triggered.
- Electrical Malfunctions: Issues with the vehicle's electrical system, such as blown fuses or corroded terminals, can disrupt the operation of the reductant pump 2 control circuit.
Symptoms of P20FC 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: The vehicle may experience a decrease in performance, including reduced power and acceleration.
- Increased Fuel Consumption: A malfunctioning reductant pump 2 control circuit can lead to higher fuel consumption due to inefficient emissions control.
- Failed Emissions Test: If the issue is not resolved, the vehicle may fail an emissions test due to increased NOx emissions.
How to Fix P20FC Dodge
- Diagnose the Issue: Begin by using a diagnostic scanner to retrieve the specific trouble code and further investigate the underlying cause of the problem.
- Check Wiring and Connections: Inspect the wiring harness and connectors associated with the reductant pump 2 control circuit for any signs of damage or corrosion. Repair or replace as necessary.
- Test the Reductant Pump 2: Verify the functionality of the reductant pump 2 using manufacturer-approved testing procedures. Replace the pump if it is found to be faulty.
- Inspect Sensors: Check the NOx sensors and other related sensors for proper operation. Replace any defective sensors that may be contributing to the issue.
- Clear Codes and Test Drive: After completing the repairs, clear the diagnostic trouble codes from the vehicle's computer and test drive the vehicle to ensure that the issue has been resolved.
Cost to Fix P20FC Dodge
The typical repair costs for addressing a P20FC DTC related to the Reductant Pump 2 Control Circuit Low can vary depending on the extent of the issue and the specific components that need to be replaced. In general, the cost of parts for a reductant pump 2 replacement can range from $200 to $500, while labor costs can add another $100 to $200 to the total repair bill. Keep in mind that the actual diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type.
