Hey guys,

So today I when to get a 12A Oil Pressure sensor thinking maybe the sensor when bad on mine. Once I have replace the sensor and turn on the car, it try to read the oil pressure but go from off position to zero and back down when is warming up with the shoke out.

Can someone give me some ideas as to where I should take a look at to trouble shot this problem?

 

First, make sure the wiring is good and the connectors are clean and the capacitor is connected. If all of that is good, pull the gauge cluster and look at the op gauge. There are fine white wires wrapped around a bi-metallic strip that you can see from the back. If the wires are browned or blackened, the guage is toast.

 

if its toast do this

Ok thanks, I think I might just get a mechanical guage and just do that because is a pain in the butt to figure this out with out taking it to auto pro electician.
