WebUnnecessary DPF regeneration: faulty sensors can also lead to unnecessary regenerations, causing inconvenience to the vehicle owner. Failed emissions test: a false reading can cause the EGR system to malfunction, without triggering the check engine light. This can result in an emissions test fail. WebData from the DPF differential pressure sensor is used by the PCM to calibrate for controlling DPF exhaust system operation. Diesel Particulate Filter Regeneration. The primary reason for soot removal is to prevent the buildup of exhaust back pressure. Excessive back pressure increases fuel consumption, reduces power output, and can …
WebA properly working DPF creates a slight back pressure. The vehicle's ECU -- computer – has back pressure sensors on the DPF to monitor its functionality. If for any reason it senses a discrepancy in the pressure limits, it will set and store ... An air leak would change the sensor readings, thus resulting in the code.
