P2465 Diesel Particulate Filter Differential Pressure Sensor Range/Performance
The DPF differential pressure sensor signal is implausible compared to engine load and exhaust flow. Either the sensor or the pressure tubes leading to it are at fault.
Is it safe to drive with P2465?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
Common causes
- Most likelySoot/water clogged pressure tubes
- PossibleSensor drift
- Less likelySensor element aged beyond calibration window
Symptoms
- Check engine light or DPF warning light on
- Power loss / limp mode
- Increased fuel consumption
- Failed forced regeneration attempts
