Oil Pressure Sensor Manufacturer

[BANDIT500]

Hi again,

Does anyone know which manufacturer makes the oil pressure switch which screws in the engine.

Think it must be Rover, but not sure.

Cheers

Dunno, but I just paid £42.28 for mine to be replaced during it's service so if you find one ultra cheaper I'd like to know.

I'll try to see if there are any marking on the new part while I'm out replacing my splitter and smaller front plate later (took splitter off in case MOT brake test wheels/dip bashed it - took plate off because it's not legal).

Switch or sender? They both screw into the oil filter head but the sender for the gauge is bigger and more expensive than the simple on/off switch for the warning light. I've bought pressure switches for five or six quid each. Allowing five minutes to fit during an oil change leaves an awful lot of profit out of that fourty quid? But if you're talking about the sender for the gauge that could be more expensive I guess.

Judging by previous threads it's the sender we're talking about not the switch. Does this mean that the problem has been traced to the engine sender Bandit or just pricing it as an easy way to eliminate one possible fault?

Doh - sorry Peter - yes, I mean't the sender. Silly me. Must read messages more carefully.

Martin,

i asked one of my work collogues who's a bit of an electrical wizard to have a look.

His dad told us to check the resistance across the sender, and generally the resistance should read 90 - 120 ohms. 0 or infinate measurement means the sender is dead.

We measured it and infinate measurement occurred.

So i've opted to buy a new sensor and hope it's that problem. If not i give in and TVR garage can have a look.

Looks like you're getting it cornered now. If you want to prove the rest of the circuit before changing the sender and you now know that the resistance should be 90 to 120 ohms, you could always try connecting a resistor within that range between the connector and earth.

Good luck and let us know when you get it fixed.

there are about 20 or so different ones that have been fitted to Rover V8s over the years. Don't assume anything !
