san marino blue Posted May 25, 2015 Share Posted May 25, 2015 Just another thing to try If gauge reads without the engine running, unplug the sender. If it the gauge then reads zero, it can only be the sender If it still reads it's the gauge, unless it's a wiring fault, but that's really unlikely 120psi after 10mins of driving, at idle is definitely not right Quote Link to comment Share on other sites More sharing options...
gimmeaclue Posted May 29, 2015 Author Share Posted May 29, 2015 Conclusion. Problem solved, oil pressure reads zero until the engine is switched on, increased to 70 when fired up and as the car warmed through on idle lowered to 30ish. I bought my new OEM sensor from Clarke Motorsport Bank holiday Monday evening. It arrived on Wednesday and at £86 was £42 cheaper than Nissan and super fast delivery, so a big thanks. Thanks to everyone who helped diagnose the problem on this thread and for the advice where to purchase. Anyone can fit one of these the hardest (most time consuming) part was removing the under tray. Had a new K+N oil filter and some Motul from Opie oils so I did an oil change at the same time, worth doing as your in that neck of the woods. 2 Quote Link to comment Share on other sites More sharing options...

san marino blue Posted May 29, 2015 Share Posted May 29, 2015 Good to hear I love oil pressure gauges, they can stop you blowing a motor Oil lights are a waste of dash space, engines RIP by the time that comes on most of the time She just wanted to know you'd love her!
