I've been having some low oil pressure issues-- it seems to be directly corrolated to the temperature of the car, so i'm working toward fixing that. My question about an oil pressure sending unit arises from a similar issue with my wife'* stratus-- it seems that on that car this unit is a commonly failing unit that can be replaced (and the low oil pressure light actually is just indicated the failing unit --not necessarily the actual oil pressure)

so- does my 94 have such a unit that would be changeable-- and how likely is this my issue?

Yes, the OPSU is replaceable. How low is low?

Oil pressure will vary with temperature as the viscosity of the oil changes. Like the difference between molasses in winter and summer. How much of a difference is there between when you first start it an say 30minutes later?

it never dips into the red but will hang just above it at idle... so i havent sweated it too much.. im planning on getting a new car in the next six months anyways...

im pretty sure the 40 line is about at 12 oclock-- its usually right above that at start... and 30min later it will reach to just above the red at idle (when above 2k rpms it is fine)

I have replaced mine for just that reason. If you pull the front passenger tire off you can access the OPSU thru the wheel well without to much hassell.

did it fix your issue?

It helped. My preassure went from a low of just above the red to about 20-30 PSI at the worst now. There is engine wear and what not so it won't always be at 40, but it'* still well above the red zone now.

good to know


thanks

would my problem be the oil pressure sending unit if the oil pressure guage likes to jump way up sometimes, doesnt quite hit 120 but sure gets close sometimes, the other day though i was commin home and it was holdin a steady 110, what do you guys think?
