P244A OBD Error Code: Problem & Solutions

<<See All OBD Codes

Error code P244A flashing? Don’t know where to start from? Well, all you need is this brief guide by Parts Avatar that’s definitely going to help you crack the error code P244A. It should be noted that the diesel exhaust fluid (DEF) installed is utilized to aid while converting the leftover exhaust particles to non poisonous gases. Also, an increased temperature in the exhaust system is required to completely burn off those particles. The task of maintaining the optimum temperature in the diesel particulate filter (DPF) is performed by the injection of the DEF fluid (when injected into the exhaust stream). Only then the system is able to convert the hazardous NOx to nitrogen, carbon dioxide and water. To reduce any NOx present in the system, the reductant catalyst (SRC) is added. The DPF moving in and out of the DPF is measured by the exhaust pressure. The error code P244A is set, whenever the pressure is low.

These diagnostic checks help to ensure that the aftertreatment diesel particulate filter is present and functioning as per the requirements. The pressure differential is monitored by the engine control module (ECM) using the exhaust pressure sensor through the aftertreatment diesel particulate filter. When the aftertreatment diesel particulate filter is not present in the aftertreatment/exhaust system, the engine control module notifies it and sets the error code P244A. Usually, this DTC is a two trip fault. This also disables the active regeneration of the aftertreatment diesel particulate filter. Immediately after the fault has been discovered, the ECM turns off the malfunction indicator lamp after the diagnostic runs and passes..

What causes this problem with the Diesel Particulate Filter Differential Pressure Too Low Bank 1 ?

• A jammed diesel particulate filter
• Exhaust leakage near the diesel particulate filter pressure sensor
• Leakages in the diesel particulate filter pressure sensor connecting hose
• The aftermarket accessories
• Performance alterations

1. Exhaust pressure sensor - Is excessive soot of smoke coming from your system? Check engine light flashing on? Fix your exhaust pressure sensor if you want to get rid of all these problems as well as the error code P244A.
2. Diesel particulate filter - Do you love hitting the roads but hate the halts? Yes, a dirty or jammed diesel particulate filter not only leads to the error code P244A but also causes problems like a deactivation of the start/stop button. Now get your error code P244A fixed right here with us. What are you waiting for? Get your filter changed now.
3. Diesel exhaust fluid pump - A clogged or damaged diesel exhaust fluid pump is the main reason that stimulates a number of problems like a potential damage to components, including DEF dosing pump and diesel particulate filter. It is advised to get it changed immediately. Log into Parts Avatar now.
4. Exhaust system parts - A lot of problems are likely to be caused due to malfunctioning exhaust system parts. Decreased acceleration and loss of power are the most common ones. So in order to avoid these, we recommend you to get your exhaust system parts replaced or repaired right away.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD code P244A here:

Common Symptoms

• At times, on the instrument cluster one may find the clean exhaust filter message
• Engine light illuminated (or service engine soon warning light)

Here are some ways with the help of which you will be able to correct the OBD code P244A:

• Repair or replace a damaged or clogged diesel particulate filter
• All the exhaust leakages present around the diesel particulate filter pressure sensor should be mended or restored immediately
• Make sure you fix all the leakages present in the diesel particulate filter pressure sensor connecting hose
• Also, one should keep a note of the aftermarket accessories and the performance modifications (they should be as per the requirements)

There is no need to be anxious as Parts Avatar – Car Parts Online is here to help you out! We have high grade exhaust pressure sensor, diesel particulate filter, diesel exhaust fluid, exhaust system, exhaust leak and a lot more for our precious customers.

Here are some steps which you should follow in order to diagnose this fault code:

A standard OBD-II trouble code scanner should be used to diagnose this trouble code P244A. The scanner will be used to check and view the freeze frame data and assess the code by a certified technician. The technician should also check for additional trouble codes stored. After the repairs have been performed, the codes should be retested and the vehicle should be restarted to see if the code pertains. If the code disappears it could likely be due to a faulty diagnose or may represent an intermittent issue.

Common Mistakes When Diagnosing the P244A Code

Only for our customers convenience we have listed here a few common mistakes that should be avoided while diagnosing the error code P244A:

• Presence of exhaust leaks
• A possible failure in the exhaust pressure sensor
