Oil pressure Gauge

When i had the front of the car jacked up off the ground i noticed that the oil pressure gauge sender is located in the oil sump plug. This cant be right can it? Now it is getting 2kg/cm2 on idle and 6kn/cm2 when driving but cant see how it would be getting a reading? I thought they had to be located on a sandwich plate at the oil filter

HI Terry,

Yeah I believe your right about the normal location for this transducer is a sandwich plate. The sump nut must have been modified to accept the sender. Its a very funny place for it alright as I wouldn't imagine there would be any pressure present at this location to measure as the sump is only a reservoir where the oil is sucked out from.

And here's a checky little plug, if you want a sandwich plate, I have a brand new G-reddy/thrust one for a scooby for sale.

mines the same way and i have the same readings as you!

maybe its your temp sensor

im getting 40psi and when everything warms up im lucky to get 10psi

temp sensor in the sump nut, oil pressure has to come from a gallery

But the only gauges i have would be volts, boost, Oil Pressure and hmm unless that thirds gauge is a oil temp guage and not a water temp which i thought it was haha.
But where is the pressure gauge reading from as there aint no sandwich plate to hold the sensor

it can be connected into where the original oil
pressue sensor is located...
