Yet another question to do with these bloody sender units guys!

If I had the original EB oil pressure sender unit hooked up to an XB GT oil pressure gauge, would it read properly?

The reason I ask is: are there two different types of oil pressure senders? One that sends a signal to say, a light, that comes on when there is no pressure and off when there is pressure (like the factory warning light). The second type will actually send a signal to a gauge that will read how much pressure is there. Is this correct or does one pressure sender do both jobs, depending on if you have a light or a gauge?

Reason is my XB GT gauge doesnt read anything when I hook up the factory wire to the EB pressure sender unit on the block. Could it mean that the sender is faulty? Could the gauge be faulty? So can I check if the gauge works by shorting the wire to the chassis or something?

Finally, does anyone know if an XC pressure sender unit will screw into the EB pressure sender unit hole? Should I try and see? (it would save me buying a new one)

Cheers

Simon

yes, yes, not 100% sure but i think yes.

Cheers Jase, I will have a look at it tomorrow and see what happens.

light and gauge senders are different.
not sure about fit between eb/xc

The presure sender is about 50mm dia.
The idiot light [correctly named] is small almost same size as temp sender unit.. in general..

As others have said, there is 2 different types, the idiot light is as xbxr8 said, about the size of the temp sender, the gauge sender is generally a small cannister, much larger than the other.

Shorting to ground should fire the gauge up, if you hook it to the switch type sender, it would assume that when ignition lights are on, the gauge would swing to full and when oil pressure is detected, it would go back to nothing.

Grab a gauge type sender from a E series S Pack/XR or Fairmont up. Only thing may be different operating ranges of gauge vs sender.

I am searching all over for this oil pressure sender to be replaced but would really appreciate if anyone could please send or post a photo of what it looks like and possibly where its located in a Falcon EA 90. Many thanks.

Found it!!!! the damn thing is located right inside on the engine body a few inches above the oil filter. tucked behind all the wires, pipes & hoses. it is so difficult to get to. now i'm in the process of replacing the oil pressure switch (aftermarket version) $8.95 which i got from SuperCheapAuto instead of Autobahn who quoted me $60.00. big difference there... thanks this forum really helps alot... much appreciated.

sorry my bad... i needed a oil pressure sender and not a switch!!! These items are different, a switch can only give readings of high & low where as a sender can give gauge reading variables suited for S pack cluster oil gauges. That means forking out $60 which is still a good buy for an oil pressure sender.

Picked up an oil pressure sender at my local Pick'n'PayLess for $10. All is OK now.
