P246D Possible Causes
- Faulty diesel particulate filter pressure sensor
- Diesel particulate filter pressure sensor harness is open or shorted
- Poor electrical connection in diesel particulate filter pressure sensor circuit
How to Fix Code P246D
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

P246D Meaning
The Powertrain Control Module (PCM) monitors the rationality of the diesel particulate filter (DPF) pressure sensor during idle and part-load operating conditions. The test fails when the diesel particulate filter pressure sensor signal value at idle is less than 0.15 kPa (0.022 psi). The test also fails when the diesel particulate filter pressure sensor signal value at part-load is below a minimum value or above a maximum value. These minimum and maximum values are based on exhaust volume.
