Standard Ignition Engine Oil Pressure Switch P/N:PS-439
Standard Motor Products
Standard Ignition PS-407 oil pressure sensor for the 1999-2001 Dodge Ram 2500 and other vehicles sends the engine's oil pressure reading to the vehicle's data monitoring system.
An oil pressure warning light that stays on, a gauge that reads erratically or oil seepage around the sensor can mean the unit is failing. A warning light can also come from wiring trouble or from real low oil pressure, so before replacing the sensor, look it over with the engine off, along with its plug and wiring, for oil residue or damage. The 1999-2001 Dodge Ram 2500 takes one.
The vehicles it fits include the 2016-2019 Mack LR600 and the 2009-2017 Blue Bird All American RE, and it is a direct replacement made for OE fit. Open the "Vehicles it fits" section to check your exact model, year and engine.
