P249F Ford Code - Excessive Time To Enter Closed Loop DPF Regeneration Control
Quick Answer
Some manufacturers are now using a Diesel Exhaust Fluid (DEF) system commonly called a Selective Catalytic Reduction (SCR) system to reduce harmful Oxides of Nitrogen (NOx). Common causes include Exhaust Leaks, Fuel contamination, Faulty Diesel Particulate Filter (DPF). Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P249F Ford Description
The system requires a storage tank for the diesel exhaust fluid, a pump with integrated level sensor, pressure sensor and fluid quality sensor, an injector fitted to the exhaust system, fluid heater and the catalyst. Sensors can also be fitted close to the SCR catalyst to monitor temperature during regeneration.
The system is closely monitored for correct operation as failure of the system will have a large impact on vehicle exhaust gas emissions of oxides of Nitrogen.
What are the Possible Causes of the DTC P249F Ford?
- Exhaust Leaks
- Fuel contamination
- Faulty Diesel Particulate Filter (DPF)
- Faulty NOx Sensor
- Diesel Exhaust Fluid
- Faulty Selective Catalyst Reduction (SCR) Catalyst
How to Fix the DTC P249F Ford?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?

Frequently Asked Questions about P249F Ford Code
What does the OBDII code P249F mean on a Ford vehicle?
1. The P249F code indicates that the diesel particulate filter (DPF) system is taking too long to enter closed-loop regeneration, which is required to burn off soot and maintain proper emissions control. 2.
What are the common symptoms of the P249F code?
Symptoms may include the check engine light turning on, reduced engine performance, increased fuel consumption, and difficulty completing DPF regeneration. 3.
What causes the P249F code to appear?
Possible causes include a clogged DPF, a faulty exhaust temperature sensor, issues with the DPF pressure sensor, or problems with the engine control module (ECM). 4.
Can I drive with the P249F code active?
Driving with this code is not recommended, as it may lead to further damage to the DPF system or other exhaust components, potentially resulting in costly repairs. 5.
How is the P249F code diagnosed?
A technician will use a scan tool to check for related codes, inspect the DPF and sensors for clogs or damage, and test the exhaust system for proper functionality. 6.
What repairs can fix the P249F code?
Repairs may include cleaning or replacing the DPF, replacing a faulty exhaust temperature or pressure sensor, fixing wiring issues, or updating the ECM software. 7.
How much does it cost to repair the P249F code?
Repair costs can vary, ranging from $200 for a sensor replacement to over $2,000 if the DPF needs replacement. Diagnostic fees may also apply. 8.
What maintenance can prevent the P249F code?
Regular maintenance, such as using the correct diesel fuel, performing periodic DPF cleaning, and driving at highway speeds to allow for passive regeneration, can help prevent this code. 9.
Can a faulty turbocharger cause the P249F code?
Yes, a faulty turbocharger can contribute to the code by affecting exhaust flow and preventing proper DPF regeneration. 10.
Is a software update required to resolve the P249F code?
In some cases, updating the ECM software with the latest factory calibration may be necessary to ensure proper DPF operation and resolve the code.
