[Mk2] [Turbo] water temp sensor part number

[raze tekniq]

Can anyone help me find a part number for a water temp sensor for my rev2 turbo. There's 2 of them coming out of the hard pipe coming from the resivor tank in the engine bay, 1's green and the lower 1 is grey/white. I've been on the epc sticky and there's nothing there I can see. Any help would be great.

Here you go mate.

83420-16040

This is the guage temp sensor.

Or if it's the green one you wanted, that's 89422-20010.

grey is cold start signal
greenis ecu signal
blue plug on other side is the guage signal

Okay thanks alot lads, its the grey one so fingers crossed I can get the part now.

[jimGTS]

but the grey one is not the water temp signal.. temp for the cold start injector, but not the ecu or temp guage in the dash.

My rev 2 has two grey sensors. The one underneath the green sensor is the cold start switch (89462-20020), the one opposite is for the dash gauge (83420-16040).

well the sensor for the dash itself is brass, and the connector on my car is blue, lol...

[ChrisW]

The connector on mine is the same style as the other sensor connectors but yours looks a bit different. Maybe you've got a non-OEM part in there?

Anyway whatever colour it is, I think we can agree that the cold start sensor has two wires and the temperature gauge sensor has one wire.

[jimGTS]

yep, and the locations.....

but mmmm, that has got me thinking.....

thing is the sensor you can see on that pic was new from toyota like 2years ago! so the connecter hooking onto it must be correct??

have you or anyone else got a pic of what theres look like?

[ChrisW]

I'll take a pic this evening. The EPC lists two alternative part numbers for that sensor, looks like they used two suppliers (Yakazi and Nippon Denso). Don't know why the plugs on the loom would be different though.

[jimGTS]

you sig says rev2, so should be the same!
ive enver thought any different of it in the 3-4years ive had the car, and i know my car inside out, its never been spotted by numerous mr2 garages, so mmmmm.....

[ChrisW]

Well I had a closer look and realised that the sensor isn't grey, it's just the connector.

Jim the sensor plug you have on your car I have only seen on Rev 1 cars N/A and Turbo, maybe it was changed at some point

ChrisW the one on your car is the same as mine Rev 2 and I have seen this connector on many other Rev 2 cars aswell.

There must have just been a difference in manufacturer and/or across Rev`s I guess.

[ChrisW]

Interesting. I hope the original poster isn't too confused now!

[jimGTS]

lol, but my cars chassis, and inlet manifold are a rev2, lol....so are my brakes, old front lip, etc etc.....

very strange.

mmmmmmm, strange one.
well i got half the engine out the car anyway, i may as well trace the cable, see if i find anything interesting.

[ChrisW]

Perhaps the production line had just switched over to rev 2 and they still had a box of the old plugs to use up?

sounds totally random, lol, but could be....
i do have a march 92 car tho, so very early rev2...

Well lads I'm totally lost, the sensor in question isn't in jimgts's pic, it would be in the bottom left of the pic coming out of the thermostat housing at least I think that's what it is. The black pipe is covering it up. I've got the ignition sensor coming tomorrow so let's hope to God its the right one, anyone need a water temp sensor?
