Looking at the throttle body, I can see that there is the Throttle position sensor, but there are other items which I have no clue as to what they are.
There are 2 air bleeds what do they do?
Also is that an airflow meter? An another component I do not recognize.

Is this the idle up solenoid? if so where should the piping goto? What about this 3 wire sensor clip where does that go?



Idle up solenoid 1


Idle up solenoid 2

Help please

Picture 1:
'air bleed' : This is the vacuum feed to brake servo. Cut off the pipe and seal it up with TigerSeal, Wurth etc.
'???': This is the idle valve which the ECU uses to allow a bit of air into the engine to maintain the proper idle speed.

Picture 2:
'Idle up solenoid': No. This is used to allow the fuel vapour from the charcoal cannister in the donor to be fed into the intake and is called the 'cannister purge solenoid'. Disconnect it, you don't need it.
The 3 pin connector: Not 100% sure on this one. I'll check my notes.

Can't see too well from the last picture, but what colours are the wires to that 3 pin plug? It might be the feed from the speed sensor on the gearbox.

The wire colours on my speedo connector are White/blue, Black/orange, Violet.

Hope this helps,
Ed.

Thank you Mr. Mad thats very useful!

Would you know what the 2nd item is that I have labeled as ???
I'm referring to the lower one.

It looks like a map sensor (manfold asolute pressure).

all above right the plug is either speedo, or fan

As Shaun says, the bottom '???' is the MAP sensor which measures the vacuum in the intake manifold.

The radiator fan connector on mine had a single large green wire going to it so I would say that the connector is definitely for the speedo sensor on the gearbox. I've just had a close look at mine and the colours I mentioned are correct for this.

I quite like being called Mr Mad! Cheers!

top ??? is the idle air control valve,the lower is a t'map sensor.the left air bleed is a servo pipe and the right is fuel pressure req vacum.the 3 pin plug goes to the vss and i cant make out the box thing.

Thanks Guys, you've all been extremely helpful. Where is the air temp sensor then?

My air temp sensor was fitted onto the side of the donor airbox right next to the MAF sensor. It's now fitted into the back of my K&N filter (if you get the right one, it's got a hole ready for it).
