Mysterious (to me) plug.

[Lancee]

Anyone know what the function of this plug/device is ? Found adjacent to dipstick tube. V70 D5 MY 2002.

I found it disconnected and have now reconnected, but have no idea what it's for. Not aware of any problem or error logged either before or after reconnection.

I have trawled Vida parts to try and find out, but not had Vida long so have failed thus far.

Time to show how clever you can be !

Thanks.

clean that tag on the wire and see if there is a part no on it.

If I'm seeing that right and that big hole is just a close up of the dipstick tube, then the connector joins to some sort of sensor on the block, surely

water temp / oil temp / oil pressure?

The white plug/connector is between the "big hole" to the right which is the turbo pipework which runs under the engine from the turbo, and the dipstick tube which is to the left. The plug as pictured is only partially inserted into what I assume to be a sensor in the block ?

"water temp / oil temp / oil pressure?", that's what I would like to know.

Because of its location I am thinking oil level/pressure/temperature, but again would like to know.

I guess I could run Vida whilst connecting/disconnecting the plug, but its not the easiest plug to get at with big hands and this seems to be a bit of a "needle in a haystack" approach.

Simmy, I suspect the label would only likely show a part number for the loom to which it is attached ?

Also thought I would throw out a challenge to the forum !

So no prize for you (yet) Stuart (or Simmy)!

That's the plug for the oil pressure sensor, part number 3545696. If you haven't got VIDA check out Partsouq. They've got all the OEM parts diagrams free to access online for loads of makes including Volvo.

ahhh yes I get it now that makes more sense

dammit my first thought was oil pressure but that was based on thinking about where it is on my mini engine and that could have been misleading so I hedged my bets

Thank you, that's really helpful, I will check it out. I knew someone on here would know.

A little surprised that no error code was flagged when disconnected, but I guess if it's a switch as such no connection means a good oil pressure is registered

And the prize goes to !

Probably academic now, but I have again trawled through Vida, and tried the suggested part number in the search facility, but to no avail.

It would seem that according to Vida my car has no oil pressure sensor (that can be found within Vida), although one is apparently fitted.

Also tried Partsouq for my Model/Year car but couldn't find the sensor.

I may look at the live data later when the weather improves !

Thanks again.

I incorrectly referred to the part as a sensor. It is indeed a switch. If you do an internet search for Volvo 3545696 and look at the images you will see the item in question. It's possible that the part number is different for your particular year and model, or the part number has been superceeded since the 2014/5 version of VIDA was released, so you may find a different part number for the same part on your copy of VIDA.

The thing I find interesting is that I can't find the part or part number for my car in Vida at all !

I can find alternative D5 engine block pictures on the internet which show the switch as you describe.

The illustration of the engine block in Vida for my car has no switch illustrated/described, and a part number/description search comes up with nothing.

I would think it unlikely that the D5 started out without an oil pressure switch of some description, and that one was added at some time later in the production run to my car.

I assume Vida, or released information must be lacking/erroneous ?

I guess there's little point in doing this to death. At the end of the day the main thing is that I/we now know what it is (the switch) and that it is connected again. Thanks to you for that.

The concern is the 100% reliability of Vida ?
