  • The automobile fault code P244B can be caused by a faulty diesel particulate filter.
  • It can also be caused by exhaust leaks before or near the diesel particulate filter pressure sensor.
  • Leaks in the diesel particulate filter pressure sensor connecting hose can also trigger this fault code.
  • Lastly, aftermarket accessories and performance modifications can also cause the P244B fault code to appear.

Below are the possible fixes for the automobile fault code p244b, including inspecting wiring harness and connectors for damage.

  • To fix the automobile fault code p244b, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The factors that influence the cost of diagnosing and fixing the automobile fault code P244B include the estimated repair time of 1.0 hour. Most auto repair shops charge between $75 and $150 per hour, which can significantly impact the overall cost.

Other factors that may affect the cost include the severity of the issue, the type of vehicle, and the location of the repair shop. It is important to consider all of these factors when determining the cost of diagnosing and fixing the P244B fault code.

The P244B fault code is related to the aftertreatment Diesel Particulate Filter. The Engine Control Module (ECM) uses the Exhaust Pressure Sensor to monitor the pressure differential through the aftertreatment Diesel Particulate Filter.

If the ECM detects that the aftertreatment diesel particulate filter is not present in the aftertreatmentexhaust system, it will set the fault. This DTC is a two trip fault and active regeneration of the aftertreatment Diesel Particulate Filter will be disabled.

The ECM will turn off the MIL lamp immediately after the diagnostic runs and passes.

What are the possible causes of the P244B fault code?

If you see the engine light on or service engine soon warning light, it could be due to the P244B fault code. This code is often caused by a faulty diesel particulate filter, exhaust leaks before or near the diesel particulate filter pressure sensor, leaks in the diesel particulate filter pressure sensor connecting hose, or aftermarket accessories and performance modifications. To fix this issue, you should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components and broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the related wiring harness and connectors to fix the P244B fault code?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a P244B fault code, there are a few things you can do to fix it. First, check for a faulty diesel particulate filter, exhaust leaks before or near the diesel particulate filter pressure sensor, leaks in the diesel particulate filter pressure sensor connecting hose, or aftermarket accessories and performance modifications. Then, visually inspect the related wiring harness and connectors for damaged components and broken, bent, pushed out, or corroded connector’s pins.
