I guess, so to speak.


Once the switch is activated, a pretty steady voltage is sent to the instrument (I don''t have the manual close by to tell you the voltage).


Autometer used to offer another sensor with an additional contact for an low oil pressure light. I was told by Explorer owners that many, especially with the 1st generation vehicles, did that.


I have never heard of any oil pump failure. The only issues with oil and lubrication I ever heard of was either due to using old oil, or oil other thanrecommended by the manufacturer.


I would think that if you don''t have any sufficient oil pressure, there would be ticking sound from the automatic lifters first. That of course does not mean that other parts already sustain damage.

The oil gauge does serve some function.. But not much.. The sending unit switch has three positions one for low (below 7psi I think) Then normal (7-50 psi I think) then one for high (over 50 psi I think).. Back when they started using this type of sensor we would replaces them with the older "bell" style sending units.. (mainly ford trucks till the mid 80''s) These will send an actual pressure reading to the gauge...

 

So max, are you saying that i could get a different sensor and it would give me a true reading?

 

PRetty much yes... I used to toy with early 90''s MN-12 cougars and T-birds with 5.0''s and 5.8''s quite a bit..We''d use a sending unit from say a 1979 F-150 with a gauge.... Dunno how this would work with a digital cluster, but it worked dandy with the analog.. I doubt they have changed the gauge itself signifigantly in later years so it should still work with the newer stuff.. the biggest issue I would see is that this type of sending unit is larger... Dunno if it would cause any clearance issues or not..

 

i''M checking for the part
