What does p244b mean on a DPF sensor?

What does p244b mean on a DPF sensor?

What Does Code P244B Mean? When a code P244B is stored, you may assume that the powertrain control module (PCM) has detected an input signal from the circuit of the diesel particulate filter (DPF) pressure sensor indicating that differential pressure is too high. This code is used exclusively in diesel powered vehicles.

What happens when PCM detects code p244b?

If the PCM detects a DPF pressure condition that is higher than programmed parameters, a code P244B will be stored and a malfunction indicator lamp may be illuminated. What are the common causes of code P244B?

Where is the pressure sensor on a DPF?

Plastic DPF pressure sensors are usually mounted away from the extreme heat of the DPF. DPF back pressure is monitored using high temperature silicon hoses (connected to the DPF and the DPF pressure sensor).

What are the common causes of code p244b?

What are the common causes of code P244B? 1 Improper DPF regeneration fluid. 2 DPF regeneration fluid reservoir may be empty. 3 Large exhaust leaks. 4 Clogged DPF pressure sensor tubes/hoses. 5 Open or shorted circuit/s in the DPF pressure sensor circuit. 6 (2 more items)

Why does my Isuzu truck have a bad DPD sensor?

If the ECU has a bad earth or ground at one earth point it may not affect normal drive but may affect other electronic components such as dpd pressure sensor causing the voltage to be out and cause the sensor to read incorrect and give the ecu a bad reading.

How much does it cost to diagnose a p244b code?

Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. The cost of diagnosing the P244B code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.

What does p244b stand for in engine control module?

P244B Meaning This diagnostic checks to make sure that the aftertreatment Diesel Particulate Filter is present and functioning correctly. The Engine Control Module ( ECM ) uses the Exhaust Pressure Sensor to monitor the pressure differential through the aftertreatment Diesel Particulate Filter.
