Frankinsubi Posted June 9, 2013 Share Posted June 9, 2013 So i was driving the loyale today and the oil pressur is just under 45 psi most of the time but out of nowhere it jumped to almost 85 psi while idle and driving.... what would cause this there is not to much oil in the car and its runng 10-30 weight. any input would be great.

Oldmics Posted June 10, 2013 Share Posted June 10, 2013 Could be the oil pressure sensing switch starting to go bad. Oldmics Link to comment Share on other sites More sharing options...

NorthWet Posted June 10, 2013 Share Posted June 10, 2013 is 85 psi the top of the scale? (as in, did the gauge just pin itself to the high end of the gauge?) Link to comment Share on other sites More sharing options...
Frankinsubi Posted June 10, 2013 Author Share Posted June 10, 2013 Yeah it just goes right to the top when you start the car, there is no hesitation. Link to comment Share on other sites More sharing options...
NorthWet Posted June 10, 2013 Share Posted June 10, 2013 The wire to the sender is grounding-out somewhere. My guess would be somewhere between where it leaves the engine loom (near the t-stat) and heads down the front of the engine to the sender.
