This is an aftermarket differential pressure sensor designed for Kenworth heavy-duty trucks.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It measures pressure difference across the diesel particulate filter (DPF) or exhaust gas recirculation (EGR) system, enabling the engine control module to manage filter regeneration and detect clogging. A failed sensor can trigger warning lights, reduce engine power, or prevent proper DPF cleaning. Replacement with this direct-fit sensor restores correct emission system monitoring and performance.
