Guide To P244B OBD Error Code Solutions
OBD Code P244B - Diesel Particulate Filter Differential Pressure Too High Bank 1
Wondering on how to solve the error code P244B?
Don’t worry, we have got you covered! Here’s all that you need to know about
the error code P244B. In order to convert the leftover exhaust particles to
harmless gases, the diesel exhaust fluid (DEF) is used to assist. A rise in the
temperature of the exhaust system is required to burn off the particles.
Consequently, the DEF fluid is injected into the exhaust stream that helps
bring the temperature of the diesel particulate filter (DPF) upto the level.
Then only the system works to convert dangerous NOx to nitrogen, carbon dioxide
and water. Further, reductant catalyst (SRC) is added to decrease any NOx
present in the exhaust stream. Also, the exhaust pressure sensor installed
measures the exhaust pressure moving in and out of the DPF. The code P244B is
stored whenever the pressure is too low.

The optimum functioning
and the presence of the aftertreatment diesel particulate filter is verified
through these diagnostic checks. Further, using the exhaust pressure sensor,
the engine control module regulates the pressure differential through the
aftertreatment diesel particulate filter. The code is stored by the engine
control module as soon as it notifies the absence of the diesel particulate
filter in the aftertreatment/exhaust system. The diagnostic trouble code P244B
is a two trip fault. Also, at times, the active regeneration of the
aftertreatment diesel particulate filter is disabled. The malfunction indicator
light is turned off by the engine control module as soon as the diagnostic runs
and passes.

Easy Diagnosis Of Error OBD Code P244B
Want to diagnose the error code P244B? Well, then you should follow these steps in order to diagnose this fault code:
A customary OBD-II trouble code scanner should be employed to diagnose this trouble code P244B. The scanner should be utilized to verify and view the freeze frame data and assess the code by a qualified mechanic. The mechanic should also check for additional trouble codes stored. After the repairs have been performed, the codes should be cleared and the vehicle should be test driven to see if the code persists. Also, it should be noted that if the code disappears it could have likely been triggered due to a faulty diagnose or may represent an intermittent issue.
