P245E Code - Diesel Particulate Filter Pressure Sensor 'B' Circuit

Quick Answer

The Powertrain Control Module (PCM) monitors the rationality of the Diesel Particulate Filter (DPF) pressure sensor during idle and part load operating conditions. Common causes include Faulty Diesel Particulate Filter (DPF) Pressure Sensor, Diesel Particulate Filter (DPF) Pressure Sensor harness is open or shorted, Diesel Particulate Filter (DPF) Pressure Sensor circuit poor electrical connection. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

What it means: P245E indicates Diesel Particulate Filter Pressure Sensor 'B' Circuit.
Common causes: Common causes include Faulty Diesel Particulate Filter (DPF) Pressure Sensor, Diesel Particulate Filter (DPF) Pressure Sensor harness is open or shorted, Diesel Particulate Filter (DPF) Pressure Sensor circuit poor electrical connection.
Severity: Moderate - service should be scheduled soon.
Can I drive?: The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P245E Description

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 less than a minimum value or greater than a maximum value. These minimum and maximum values are based on the volume of exhaust.
