Regarding Ford vehicles, it is not uncommon for drivers to experience car issues. One of the most common issues that drivers experience is a Ford Code P24A0. This code indicates a closed loop DPF regeneration control at a limit – temperature too low. The PCM monitors the exhaust gas temperature bank 1 and sensor 2 (EGT12) to ensure the diesel oxidation catalyst exit temperature is high enough to complete regeneration. This DTC is set when the difference between the expected and actual diesel oxidation catalyst exit temperature exceeds 20°C (36°F). To help drivers better understand the issue and find potential solutions, we have created a table outlining the causes and solutions.

Table of Causes and Solutions of Ford Code P24A0
| Cause | Solution |
|---|---|
| Fuel injection concern | Check the fuel injection system for any issues. |
| Damaged diesel oxidation catalyst | Replace the diesel oxidation catalyst. |
| Biased EGT12 sensor | Test the EGT12 sensor and replace if necessary. |
| Biased exhaust gas temperature bank 1, sensor 4 (EGT14) sensor | Test the EGT14 sensor and replace if necessary. |
Fuel Injection Concern
A fuel injection concern can be at the root of Ford Code P24A0. To determine if this is the cause, check the fuel injection system for any issues. If a fuel injection concern is identified, proper repairs should be made to ensure the system works properly.
Damaged Diesel Oxidation Catalyst
A damaged diesel oxidation catalyst can be the cause of Ford Code P24A0. If the diesel oxidation catalyst is damaged, it can cause the DPF regeneration to occur at a lower temperature than is needed. If this is the cause, the diesel oxidation catalyst should be replaced.

Biased EGT12 Sensor
The EGT12 sensor can become biased and cause Ford Code P24A0. To determine if this is the cause, the EGT12 sensor should be tested. If the sensor is limited, it should be replaced.
Biased Exhaust Gas Temperature Bank 1, Sensor 4 (EGT14) Sensor
The EGT14 sensor can become biased and cause Ford Code P24A0. To determine if this is the cause, the EGT14 sensor should be tested. If the sensor is biased, it should be replaced.

Conclusion
Ford Code P24A0 indicates a closed loop DPF regeneration control at limit – temperature too low. The causes of this code can be a fuel injection concern, a damaged diesel oxidation catalyst, or a biased EGT12 or EGT14 sensor. With the right diagnosis, drivers can take the appropriate steps to fix the issue and get their vehicle running smoothly again. For drivers experiencing Ford Code P24A0, understanding the causes and solutions of this code is key to dealing with the issue.
