If the sensor doesnt work properly, it could make your check engine light come on and cause the engine to hesitate or stumble. During engine testing, the Cummins engineers have determined the allowed pressure difference levels on the DPF. In the most extreme cases, a DPF failing can create an environment where the exhaust gas can not be fully purged. You dont want to go to all the effort and spend valuable time and money replacing a sensor only to have it fail prematurely because it is a poor-quality replacement part.
