Oil guage off the scale

[awager]

Chim 400hc (1996)


Got about a mile down the road today and noticed my oil pressure gauge was off the scale (90).

Only had a couple of miles to go so carried on (taking it easy) and parked up.

When I came back to the car and turned ignition on the gauge immediately went over to about 80 ish.

Now I am assuming that this is probably electrical - loose connection - or the sensor itself.

Question is - where is the little bugger. Is it near the oil filter?

Anyone know or any ideas if this could be something more serious??

remove the connection clean it with wet and dry and put it back, if this does not do the trick you need a new one .mine was a different problem it read 0, i tested it by putting the wire to earth (chassis) then it read 90 so i had to purchase a new one .

Thanks Daz - was going to do that but just wanted to check where the thing is before I start crawling around underneath.
is it near the oil filter??

theres two types one and two connection, mine is the single connection for the later models , it looks a little like a brass colour small cylinder . it was not a problem for me as i can use a four poster ramp.

No ramp for me but a decent sized jack and stands.

thanks

Recently had the same problem with mine, oil pressure dropped to 0, then shot off the scale and stayed there. Tried cleaning the connection but it was buggered so stuck a new one on - problem solved and very easy to change. Got mine from my local TVR garage for about £40

Thanks guys - will give it a go tomorrow and see what happens.
