DPF Test Kit

135.83 $

The Diesel Particulate Filter (DPF) uses sensors to monitor its status to ensure it is operating correctly. When conditions are not met, the computer informs the operator with a DPF warning lamp.

One of these sensors monitor differential exhaust pressure before and after the DPF filter. The sensor is exposed to extreme elements including heat, carbon and condensation. This may lead to a failure of the differential pressure sensor by sending false data to the ECU. This can trigger DPF related fault codes which can result in the unnecessary replacement of the DPF.

To avoid misdiagnosis and confirm the system is operating within specification, connecting an analogue gauge with the differential pressure sensor will provide an accurate reading.
