How do DPF pressure sensors work?
How does a DPF pressure sensor work? The DPF sensor measures the pressure drop across a DPF. A DPF pressure drop increases with increase in the soot mass accumulated in the DPF. Small soot mass accumulation results in lower DPF pressure drop, while high soot mass accumulation would yield higher DPF pressure.
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.
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 it mean when check engine light is on but no codes?
No code being generated on the reader does not mean the driver is in the clear. In fact, when the light is on, the odds are just as high that there has actually been something wrong for a while even if no code is generated.

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.

How to diagnose Diesel Particulate Filter ( DPF )?
Many passive and active DPF regeneration systems demand to be driven under heavy loads or at a minimum level of continuous acceleration over a set period of time, before regeneration can be completed. My diagnosis typically begins with a visual inspection of system harnesses and connectors.
