oil pressure light on

Recommended Posts

Hello, newbe  here with a question.

I have a 2004 Patrol 3.0 ish diesel with oil pressure light on when starting cold and wont go out unless you turn off and on several times?

Switch sticking, is that a common fault?

And part number if possible,

 

May thanks for your observations

I have since read on here this is a common fault, there are two switches on either side of the engine.

Are the switches the same  and I dont see any reason to replace the resistor if the switch is staying grounded.

Thanks

G'day,

The switches are not same, and the resistor is upgraded one. What might happen is that the replacement switch will fail again due to the resistor.

That is/was explicit warning on the Nissan repair bulletin.

Part numbers:

LHS switch --->  25240-8996E   (low side)

RHS switch --->  25240-2X90    (high side)

One of the difference is that RHS switch is marked with green circle as well. 

I tried to swap them around as to what will happen and the oil light will not go out if the low side switch is on the high side!

Regards

Wow and thank you very much , my problem is intermittent, and being a newbe I am not exactly sure what the designation is for this model hence does it actually have a second switch.  2004 patrol 3 litre diesel. I had a look at the exhaust side and couldnt find another switch?  Any help with the location?  I ASSume its on the other side (exhaust )? Many thanks and I dont think the resistor is bad as it is intermitant?

The usual location of oil switches/sensors on ZD30 ===> Note bellow explanations refer to "common rail " version of ZD30 2007 onwards hovever the location is the same on previous model too.

If you only have one than it is the one on LHS image. Which means no resistor either, easily checked by disconnecting the plug when engine run if the light is on it will go out.....
