Oil Pressure sender testing

[ninja.turtle007]

I'm having problems with oil pressure. Well according to my oil pressure gauge I am. I have always had really good pressure at over 40 psi. But today it dropped to 0 on tick over and went up to 15 psi at 2k rpm.

I presume the resistance can be measured with a multimeter? Or is it a case of swapping the sender unit as I don't want to spend £125 on a pressure tester?

Hello,

when this happened to me it was because the oil pick up strainer was blocked - you can indeed test the resistance - the values I believe are 10-180 Ohms for 0 to 10 bar (assuming it's VDO or compatible) - I'm not sure that's linear but might give you an idea.

Hope it's just an electrical fault.

can lend you a wet pressure tester that will fit a wbx and I believe will also do those dirty diesels as Clive used it on his

Thanks, Aidan. Just ordered a tester from EBay, was only £40 delivered. Worth having in the tool kit.

I will give you a ring at some point to discuss gear box mods on the Westy.

This is why I fitted a wet gauge in the cab.
No erogenous readings

Tester turned up, seems to be very good value.

This is at tick over


And this is at 2k RPM



I'm happy with that.
