What is OBD-II Code P244E – Exhaust Temperature Too Low For Particulate Filter Regeneration Bank 2



Section 1: Understanding OBD-II Code P244E

If your car is giving you a check engine light with the OBD-II code P244E, then it means that your car has a problem with the exhaust system. Specifically, it indicates that the temperature of the exhaust system is too low for the particulate filter regeneration process. The code is detected by the PCM (Powertrain Control Module) and stored in the car’s memory. The PCM is a vital component of your car’s onboard diagnostics system.

The particulate filter regeneration process is designed to reduce the amount of harmful emissions that your car generates. Particulate filter regeneration is done by burning the trapped particles in the filter at a high temperature. During this process, the temperature of your car’s exhaust system needs to be high enough to ignite the trapped particles and burn them off.

Section 2: Symptoms of OBD-II Code P244E

The most common symptom of OBD-II Code P244E is the illumination of the check engine light in your car. You may also experience a decrease in the performance of your car, such as reduced acceleration or power. In some cases, you may also notice a foul smell coming from the exhaust system or see black smoke coming out from the tailpipe. It’s essential to note that these symptoms can be caused by other issues with your car’s exhaust system as well.

Section 3: Causes of OBD-II Code P244E

There are several reasons that can cause OBD-II Code P244E to appear in your car. The most common cause is a faulty temperature sensor that is not picking up the correct temperature of the exhaust system. Another reason could be a malfunction in the particulate filter system, which is preventing the filter from properly trapping the particulate matter. A clogged filter, damaged filter, or fuel contamination can also lead to this error code.

Section 4: Diagnosing OBD-II Code P244E

Diagnosing OBD-II Code P244E requires the use of a scan tool. You’ll need to connect the scan tool to your car’s OBD-II port to read the code stored in your car’s memory. Once you have the code, you’ll need to examine the temperature sensor to see if it’s functioning correctly. If the sensor is not functioning as intended, it will need to be replaced. You’ll also need to examine the particulate filter system to check if it’s functioning correctly. Visual inspection and cleaning or replacement of the filter may be required.

Section 5: Repairing OBD-II Code P244E

Once the root cause of OBD-II Code P244E has been diagnosed, you can begin repairing it. The first step is to fix any issues with the temperature sensor. If the sensor is faulty, it will need to be replaced. You’ll need to remove the old sensor and install a new one in its place. If the issue lies in the particulate filter system, then cleaning or replacement of the filter may be needed.

Additionally, if your car is still under warranty, then you can take it to the dealership to get it repaired for free. If not, then you can choose to repair the issue yourself or take it to a mechanic for repairs.

Section 6: Frequently Asked Questions

1. Can I continue driving my car if it has the OBD-II Code P244E error code?
If the check engine light is on, it’s recommended that you don’t drive your car for an extended period unless essential. Continuing to drive your car with this error code could cause further damage to your car’s exhaust system.

2. How much does it cost to repair OBD-II Code P244E?
The cost of repair can vary depending on the root cause of the issue. Repairing the temperature sensor can cost anywhere from $50-$200, while cleaning or replacing a particulate filter can cost anywhere from $500-$2000.

3. How long does it take to repair OBD-II Code P244E?
The repair time can vary depending on the root cause of the issue. Repairing the temperature sensor typically takes a couple of hours, while a particulate filter system repair can take 4-6 hours.

4. How can I prevent OBD-II Code P244E from occurring in the future?
Following your car’s recommended maintenance schedule and using high-quality fuel can help prevent issues with the exhaust system.

5. What should I do if the error code reoccurs after repair?
If the error code reappears after the repair, it’s essential to take your car back to a mechanic to diagnose the problem and fix it.
