Rustyfriend Posted June 19, 2009 Share Posted June 19, 2009 Just got home from a quick 30 mile drive with my Z that was recently converted to turbo. All of the gauges were looking good in their reading and when I got home and went to shut it off, the oil pressure needle was below zero. Any ideas? I am thinking if the gauge is working and I am indeed getting no pressure, than it would be zero right? The needle is below zero to its "max" low so possibly either the gauge is dead or the wire came disconnected from the sensor on the block on the passenger side?

zedman240 Posted June 19, 2009 Share Posted June 19, 2009 Check the gauge/wiring by earthing the sensor wire to the block and switch ignition on and the needle should move to max pressure. If you get no movement, wiring / gauge is at fault. If the needle mooves all the way to max, replace your oil pressure sender. Quote Link to comment Share on other sites More sharing options...
Rustyfriend Posted June 19, 2009 Author Share Posted June 19, 2009 Alright, thanks. I will try that in the a.m. when it is light out again. I don't know if this will help any but on the drive home for like 5 minutes that gauge light quit and then came back on after the said 5 minutes.

Rustyfriend Posted June 19, 2009 Author Share Posted June 19, 2009 Well I started her up this morning to double check the gauge before I went ahead and did the tests, and oil pressure is fine. You gotta love the electrical gremlins in a Z! Quote Link to comment Share on other sites More sharing options...
