Rb26Dett Oil Pressure Sensor Replacement

[Samuel Leonard]

I got sick of my oil pressure reading very low when warm (0 to .5 on the factory guage)

so i decided to replace the sensor. You will need an open ended 17 mm spanner and

you will need to undo a hose clamp (mine was a small socket to undo)

this side of the engine bay.

undo the bottom fuel line hose clamp and slide it off (it is the return line so there is no pressure in this line but some fuel will dribble out so be careful)

this is the fuel pressure sensor about 20 cm below the fuel line hopefully you can see it in focus down there with a rubber gromet over the plug on the left hand end of it.

this is what the plug looks like with the grommet pulled back. fairly easy to remove.

you need to get a 17mm open ended spanner on the sensor to undo it.

this is the new sensor i bought off ebay from nissan of chesapeake in usa. it cost me $95 delivered here.

and this is the end result. a good oil pressure reading in the cluster guage. may not be highly accurate but it would certainly be able to warn you of a problem before it does too much damage.

Afternoon all,

Confirming this guide was fantastic! Oil pressure sensor on my R33 GTR went the other week, ordered a new one off Just Jap.

I used a 17mm stubby spanner from Supercheap Auto ($26 for the set).

I didn't have to remove the fuel line, just pull off the seal boot, unclip it, feel you way around, put the spanner on and undo it. Cleaned up around where it screws in as there was a little oil coming out.

Note, I used some Red Gasket RTV high temp gasket maker to put about 5mm run around the bottom of the screw in bit to then seal it (nissan manual recommends this as well).

Left it an hour, tightened it up and off I went.
