Ford Code P249F is a diagnostic trouble code (DTC) generated by the powertrain control module (PCM) when the time taken to enter closed loop DPF regeneration control is excessive. This code is triggered when the PCM detects that the amount of time spent in a closed loop regeneration event is less than the threshold set by the manufacturer. A number of causes can lead to this code, such as a damaged exhaust gas temperature bank 1, sensor 2 (EGT12) sensor, fuel injection concern, damaged diesel oxidation catalyst, biased diesel particulate filter pressure bank 1, sensor 1 and a damaged diesel particulate filter pressure bank 1, sensor 1. To help resolve this issue, Ford has issued Service Bulletin 12-5-12.
Causes and Solutions for Ford Code P249F
| Cause | Solution |
|---|---|
| Damaged exhaust gas temperature bank 1, sensor 2 (EGT12) sensor | Replace the sensor |
| Fuel injection concern | Re-adjust fuel injection |
| Damaged diesel oxidation catalyst | Replace the catalyst |
| Biased diesel particulate filter pressure bank 1, sensor 1 | Reset the filter pressure |
| Damaged diesel particulate filter pressure bank 1, sensor 1 | Replace the filter pressure sensor |
The Ford Code P249F is a diagnostic trouble code (DTC) generated by the powertrain control module (PCM) when the time taken to enter closed loop DPF regeneration control is excessive. This code is triggered when the PCM detects that the amount of time spent in a closed loop regeneration event is less than the threshold set by the manufacturer. To diagnose and remediate this code, it is important to understand the underlying causes and potential solutions. Common causes of Ford Code P249F include damaged exhaust gas temperature bank 1, sensor 2 (EGT12) sensor, fuel injection concern, damaged diesel oxidation catalyst, biased diesel particulate filter pressure bank 1, sensor 1, and damaged diesel particulate filter pressure bank 1, sensor 1. Solutions for these causes range from replacing the sensor, re-adjusting fuel injection, replacing the catalyst, resetting the filter pressure, and replacing the filter pressure sensor. To help resolve this issue, Ford has issued Service Bulletin 12-5-12. With the right knowledge, Ford Code P249F can be resolved quickly, safely, and effortlessly.
Replacing the Sensor
When the exhaust gas temperature bank 1, sensor 2 (EGT12) sensor is damaged, it is necessary to replace the sensor. This can be done by locating the sensor and unplugging it from its wiring harness. Once it is removed, the new sensor can be installed in the same position and connected to the wiring harness.
Re-Adjusting Fuel Injection
In some cases, the cause of Ford Code P249F may be a fuel injection concern. This can be remedied by re-adjusting the fuel injection system. This process typically involves using a scan tool to monitor the fuel injection system and make the necessary adjustments to ensure proper operation.
Replacing the Catalyst
When the diesel oxidation catalyst is damaged, it needs to be replaced. This can be done by locating the catalyst, removing the old catalyst, and installing the new catalyst in its place. It is important to ensure that all components are properly secured and that the installation is done according to the manufacturer’s instructions.
Resetting the Filter Pressure
In some cases, the cause of Ford Code P249F may be a biased diesel particulate filter pressure bank 1, sensor 1. This issue can be remedied by resetting the filter pressure. This process typically involves using a scan tool to monitor the filter pressure and make the necessary adjustments to ensure proper operation.
Replacing the Filter Pressure Sensor
When the diesel particulate filter pressure bank 1, sensor 1 is damaged, it needs to be replaced. This can be done by locating the sensor, removing the old sensor, and installing the new sensor in its place. It is important to ensure that all components are properly secured and that the installation is done according to the manufacturer’s instructions.
