The sensor has an o ring and a metal or plastic retainer
The wiring then goes to ECU. Pins 2 & 7 l think. It has a varying resistance as coolant temp adjusts or warms/cools.



This may help...

Nice one Stu. Many thanks

Your welcome Smiffo
Good to see some young blood keeping these buses on the road.

Started looking at and cleaning some of the bits today, that I have acquired.

One of the throttle bodies is worn - enough that the switch doesn't always close on what would be idle position.
( Worked that out after adjusting and it only to find it clicked intermittently again. )

The second throttle body I have is so gunky you can hear debris grinding as it operates, but seems no lateral play on spindle. Going to have a go at cleaning that up I think.

Both switches work though. one position 0.1-0.2 ohms, and the other is open circuit. That's at least one plus.

Then I thought I would disassemble and give it all a good clean, only to find pinholes in what I think would be called the inlet manifold for the RHS...

Hoping I can get a good setup out of the two sets I have here

Yes, that is daylight shining through pinholes!



Not sure whether that's a serial number, or date 

every rubber seal is solid, perished and cracked, so going to need to replace those.
 

And I think these have had it....

Smiffo,
I may have some good injectors for you. Recently cleaned and with new pipes and seals.
Just need to fit new ones. Cant do so for about a week though.
Regards
Stuart

That would be awesome Stu!

There is no rush - I'm not planning on being ready to install everything until at least in the autumn.
Ping me a DM when you're ready, with a price too.

Will do. Or if l go to Bristol can bring them along. It's a set lve used for about 2k without issues.

Also think I've cleaned and adjusted the throttle body to the point it functions correctly.

There is a stop screw too. On mine it is wound out way too far. ( A few mm on each of the two throttle bodies I have. )
This sounds like a daft question, but what's it for?

I know that sounds like asking the obvious, but it stops in the closed position anyway. Why would I need the screw? 

Bung up a photo. Not sure which screw this is?

Will do in the morning mate. The Mrs has finally managed to get me to remove the van bits from the kitchen - if I bring it back in before dawn, she will divorce me, I'm sure! 

Found a vid with it it. Screenshot here.

It looks like it would be used to prevent throttle valve from fully closing, but both of my throttle bodies I have had this screw wound so far out it was never going to touch.

The question I can't work out is that it closes properly ( I think ) anyway, so why the need for the screw to be wound in close?

Sorry Steve, for some unknown reason lm not getting forum reply emails?
I can look at my camper tomorrow...to see if it has same set up.

Right. I think I know now.
It isn’t used to stop the throttle valve closing - it’s used to set the point where the idle switch activates I think.

Watching the vid to set it up, you wind it until you can only put a sheet of paper in the gap.
Then it looks like specific feeler gauge is used in that space to slightly open the throttle valve.
At that point you set the idle switch to open at that setting - this should give correct operation.

Makes a bit more sense now I’ve watched that
