NOx Sensors for Semi Trucks
A NOx sensor fails quietly: the light comes on, the truck derates, and the shop bills for diagnosis before it bills for the part. We stock inlet and outlet sensors for Detroit DD13, DD15 and DD16, Cummins ISX15 and ISB 6.7L — including A0101531828, A0101538128 and 2894945 — in the 12V four-pin pattern the Freightliner Cascadia and Western Star use. Inlet and outlet are different parts on the same engine; the listing says which one it is.
