Data confidence85%
The control module judged the Particulate Filter Pressure Sensor B signal implausible: it stayed inside electrical limits but did not match the value expected for the current operating conditions.
Symptoms
MIL or DPF warning illuminated
Possible reduced power or limp mode
Possible frequent regeneration attempts
Possible causes
Wiring
DPF pressure differential sensor
ECM
Recommended checks
Read soot load, ash load and differential pressure values
Check differential pressure sensor and hoses
Verify exhaust gas temperature sensor readings
Check for related injection, EGR or boost codes
Verify regeneration conditions can be met (trip profile)
Powertrain: engine, transmission and driveline systems.

Frequently asked questions about P245F
What does P245F mean?
Particulate Filter Pressure Sensor B Circuit Range/Performance. The control module judged the Particulate Filter Pressure Sensor B signal implausible: it stayed inside electrical limits but did not match the value expected for the current operating conditions.
Is P245F generic or manufacturer-specific?
P245F is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove P245F at file level?
If the fault logic lives in the ECU calibration, yes: our DTC Removal file service disables the specific fault entry. Checksum correction is not included: it is a separate, optional service. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
