Oil Pressure Sensor: Description and Operation

GF18.40-P-4000MCC Component Description For The Oil Pressure Switch
- ENGINE 132.9 in MODEL 451.3 /4







S41/1 Engine oil pressure switch

Location
The oil pressure switch sits at bottom right on the oil filter flange.

Task
The oil pressure switch detects the engine oil pressure and leads this to the ME-SFI [ME] control unit (N3/10).

Function
As soon as there is sufficient oil pressure applied at the switch it opens and thus interrupts the electric circuit. This serves the ME-SFI [ME] control unit as information about sufficient oil pressure in the oil circuit. The oil pressure warning lamp (A1e30) in the instrument cluster (A1) goes out.
