The RAM P24A0 code is a diagnosis trouble code that signals the possibility of a closed loop DPF regeneration control reaching its limit due to a temperature that is too low. This code is one of the most commonly encountered codes in cars and trucks and is often the result of a failure in the Powertrain Control Module (PCM) to reach the target regeneration temperature. In this article, we will discuss the causes and possible solutions for the RAM P24A0 code.
Causes and Solutions for RAM P24A0 Code
| Cause | Solution |
|---|---|
| Exhaust Temperatures Not High Enough to Actively Regenerate the Aftertreatment Diesel Particulate Filter Due to Operating in Light Load Conditions | Adjust the engine load to increase the exhaust temperature. |
| Fuel or Emission Related Faults | Have the vehicle serviced for any fuel or emission related faults. |
| Exhaust Temperature Sensors Failed In-Range Low | Replace the exhaust temperature sensor. |
| DOC/DPF Catalyst Missing | Replace the DOC/DPF Catalyst. |
| DOC/DPF Catalyst Damaged | Replace the DOC/DPF Catalyst. |
When you encounter a RAM P24A0 code in your vehicle, it is likely the result of a closed loop DPF regeneration control reaching a temperature that is too low. This code can be caused by a number of factors, such as exhaust temperatures that are too low to actively regenerate the aftertreatment diesel particulate filter, fuel or emission related faults, and failed or damaged DOC/DPF catalysts. The solutions to these issues vary and can include adjusting the engine load to increase exhaust temperature, having the vehicle serviced for any fuel or emission related faults, and replacing the exhaust temperature sensor and/or DOC/DPF catalysts.
Exhaust Temperatures Too Low
The RAM P24A0 code is often caused by exhaust temperatures that are too low to actively regenerate the aftertreatment diesel particulate filter due to operating in light load conditions. This is a common problem for vehicles that are usually running in light load conditions, such as taxis, delivery vehicles, and other vehicles that are used for short distance trips. The solution to this issue is to adjust the engine load to increase the exhaust temperature to allow for active regeneration of the aftertreatment diesel particulate filter.
Fuel or emission related faults can also be the cause of a RAM P24A0 code. This could be caused by a faulty fuel injector, worn spark plugs, or a faulty air/fuel ratio sensor. The solution to this issue is to have the vehicle serviced for any fuel or emission related faults.
Exhaust Temperature Sensors Failed In-Range Low
The RAM P24A0 code can also be caused by the exhaust temperature sensor failing in-range low. This can be caused by a faulty exhaust temperature sensor or an air leak in the exhaust system. The solution to this issue is to replace the exhaust temperature sensor.
DOC/DPF Catalyst Missing or Damaged
The RAM P24A0 code can also be caused by a missing or damaged DOC/DPF catalyst. This can be caused by a faulty DOC/DPF catalyst or a damaged exhaust system. The solution to this issue is to replace the DOC/DPF catalyst.
Conclusion
The RAM P24A0 code is a diagnosis trouble code that signals the possibility of a closed loop DPF regeneration control reaching its limit due to a temperature that is too low. This code can be caused by a number of factors, such as exhaust temperatures that are too low to actively regenerate the aftertreatment diesel particulate filter, fuel or emission related faults, and failed or damaged DOC/DPF catalysts. Solutions to the RAM P24A0 code can include adjusting the engine load to increase exhaust temperature, having the vehicle serviced for any fuel or emission related faults, and replacing the exhaust temperature sensor and/or DOC/DPF catalysts. It is important to remember that any time the RAM P24A0 Code is encountered, it should be addressed immediately before any further damage is done to the vehicle.
