For some reason the other week my oil pressure gauge ( Standard Escos one in the dash ) shot up off the scale, and doesn't move at all unless you turn the engine off and it goes to the bottom like normal
Anyone know what the problem is?

 

have you checked the wiring from the main sender unit?

just incase the wiring has deteriorated/broken or maybe even shorting on something

 

Kelv wheres the main sender unit?
All the wiring behind the dash has just been checked so I've ruled that out

 

The oil presure switch is under the inlet manifold, towards the back where the water temp sender is.
you shouldnt be able to miss it, it should be sat upright, and a round bulb shape (ish) with 2 pins/wires that fix on top of it with 6mm nuts.

if you have no joy ill try and get a pic for you later on.

 

sounds like its earthing out,i should trace the wires by feel first, under the inlet to the sender and see if they are both still connected as they are pretty fragile [esp if the inlets been removed or messed with previously] its a t*at to get to though

 

I'm with Kelv and Nick on this, recon the wire has come away. The sensor is in a proper shitter of a place to get to thou

 

Give Jeremy Beadle a call to give you a hand Gaz!

OOPS Scratch that, he's dead!

Oh well Let the cramp commence!

 

this is what the Oil Pressure Sender looks like (also known as a VDO Pressure Sender).


I have this exact same problem, i changed the Sender unit to a brand new Ford Item £103 and still didnt change it, but i have an oil pressure problem at the mo, which is going back in to be looked at, so thinking it may be something to do with that, but wont find out until the pressure is sorted out.

I will keep you posted mate if mine gets sorted and what the cause is.

 

Cheers for the advice lads, I'll have a look tomorrow

Well apart from Jase

 

Just so you can see where it is located (picture courtessy of the hairy one - so he does have his uses ):

 

'Look Ma I'm famous!!!'

 

your very famous indeed, if only you were aware of how famous!!

 

Why do I get the feeling I shouldnt ask!

 

milkman, Mine is back to normal now.

As i said before, i had a slight problem with my Oil Pressure (due to the Strainer being blocked with Shite), this was sorted, but the gauge was still the same, but Joe @ GSmotosport said that a small bit of shit was stuck in the system that the sender unit reads from, he cleared this and the gauge starting working normally.

Hope this is off some help.

 

since i converted autronic my guage has been the same off the guage my defi reads good pressure anyway, just annoying the std one plays up!!!
