This is normal. The 2005s have a real gauge, after 2005 they went to a 'dummy' gauge.jlwardn wrote:I bought a Pathfinder that had the transmission replaced and also the radiator by-pass. I notice that my oil pressure gage is just above the low mark when it is at idle and in drive with my foot on the brake. It goes up to half way between the two marks when normal driving. When I come to a stop it drops back down. I just looked at and drove 2 other Pathfinders and their gages were above the half way mark. They are about 3/4 the way to high.
Anyone have issues like this? I appreciate any input you guys might have.....
What does a "dummy" gauge do?disallow wrote:This is normal. The 2005s have a real gauge, after 2005 they went to a 'dummy' gauge.
Make sure to buy the right one, the 'dummy' gauge for the 06+ won't work, the harness and connector is different.
The gauge in the 05s showed the real time pressure. If it changed even slightly, the gauge would move. For instance, at idle, the gauge would read on the low side, and if you gunned it with the engine cold, it would go to the high side.nutbar78 wrote:What does a "dummy" gauge do?disallow wrote:This is normal.

Very clear, thanks. I have to '05 so I know what you are saying. This gauge moves all over the place. I too like the real time info. Now if only my MPG's were real time!disallow wrote:The gauge in the 05s showed the real time pressure. If it changed even slightly, the gauge would move.

This required a 3-wire harness from the oil pressure sender to the BCU, and in turn to the gauge on the dash.
In the 06+ Pathy's they went to a 'dummy' gauge. This sender only has 2 wires, and basically brings the gauge on the dash to the 'normal' level for the driver to see. Only if the pressure dropped below the minimum requirement, did the gauge move, but at this point, your oil light is already on.
Hope that adequately explains it. I personally prefer the non-dummy version, I'd rather know whats going on. However, you can see Nissans reasoning to change, they probably got a lot of service on warranty for people worried that their oil pressure was too low or high. Also, it looks like the 2-wire version of the sender is about 1/8 the cost of the 3-wire.
