After a LIM replacement, both my fuel and oil pressure gauges were off scale high. I popped the dash a couple of times and the fuel gauge started working correctly, but no such luck with the oil pressure gauge. The gauge does move but almost like it is wired up backwards.
I have no idea where the oil pressure sending unit is located, or if this was one of the many connectors that I removed during my LIM replacement.
Any thoughts.

 

It is on the back of the intake manifold under the distributor. You have to pull the entire distributor assembly to get to it.

 

Thanks. Any thoughts on why it has malfunctioned after a LIM replacement? Worked fine before.
