DiscoHere Posted October 25, 2022 Share Posted October 25, 2022 Hi all. Does anyone know what the sensor under the oil filter on a Disco 2 2003. TD5 engine is for. There are 2 wires coming from it (black and white) and running over the top of the gearbox and then vanishing into the invisible area there. The sensor has a yellow cover to which the wires are attached. The reason I ask is that I was changing the oil in my Disco and saw one of the wires is unattached but there are no warning lights and the Disco is going just dandy. Any suggestions Quote Link to comment Share on other sites More sharing options...
Escape Posted October 26, 2022 Share Posted October 26, 2022 That would be the oil pressure switch. Does the oil pressure warning light come on when you turn on the ignition but don't start the engine? Probably not, as it needs both wires connected. Not a real problem, until you actually do encounter low oil pressure, so best sort the wiring. Quote Link to comment Share on other sites More sharing options...
