what colour is the plug which goes into the idle speed control valve (auxillary air device)

thanks,

dave

 

black i think

 

the reason i ask is because i have a blue plug on mine which i think should be on the cold start valve. the plug on my cold start valve is yellow.

the cold start valve SHOULD be blue right?

 

mines a blue plug on my cold start valve

 

yeah, i think they have been wired up the wrong way round.

could explain the idling problem ive been having!

 

my idle speed control valve plug is black and the cold start valve is blue hopes this helps bud

 

that does help, there is a plug that goes into the block almost under the inlet manifold, what colour is this suppoosed to be? on my car it is black and im wondering if this is where the yellow plug is supposed to be.

 

just checked my car for you bud idle is defo black cold start blue and i have a green plug on the inlet manifold ? that was all i could see

 

thanks mate, will go and have another look at my car.

 

green plug is the knock sensor

 

took a couple of pictures to help explain my problem.

first picture shows the green knock sensor plug on the side of the inlet manifold.



second picture shows (looking down between inlet manifold pipes) the cold start valve with a plug beneath it. what is this plug for and is it the correct one as i think the black plug which is in it at the moment should be the one on the idle speed control valve (which currently has a yellow plug on it).

 

That one you are questioning is the thermo time switch which controls the CSV. It should have a brown plug to it.

CSV - blue plug
Aux air device - black plug
Thermo time sw - brown plug
coolant temp sensor - yellow plug

If the yellow plug is disconnected or the sensor is faulty, it will run like a c unt.

 

ok thanks for that mate, very helpful post

 

update: just been reading haynes wiring diagram and i think i got all the plugs sorted. they must have put the wrong plugs in when the engine got rebuilt last september. :s

 

where exactlty is the yellow one meant to be plugged into daz? i think i left mine unplugged, cunt to start but runs fine otherwise

 

i found the yellow plug right underneath the inlet manifold. plugged into the bottom of it almost you have to reach under.

since putting the plugs in the right way (hopefully) the car has been shit at starting. will take a while to fire up and then when it does it will idle normally for about 30 seconds and then stall. after this it will stall everytime i try to start it.

 

Usually if you leave that disconnected it will run extremely rich and over fuel. Disconnecting the coolant temp sensor tells the ECU the temperature is -40 degrees and it dumps loads of fuel into account for it. It should black smoke like fook it has that much extra fuel.

It's under neath the manifold. Easier to see from under neath.

 

ahhh, hmmmmmmm!!!

when i first started my car it was smoking like a twat, and i was told my turbo oil seals had seized cos the turbo lay off the car for a year with no oil in it so got some fancy breather and it stoped smoking!? i'll need to go out and check if that plug is still off or not?

It should be on. If it's not on then you sould have black smoke AND running problems. If it's disconnected and you don't have smoke/running problems, then there is something wrong with the car.

 

Had a look earlier, couldnt see it, i assume AVA plugged it on if i didnt, but it's not to be seen!

 

Does anyone know the way to Amarillo?

 

where does the aux air device plug in??? i know it goes to the idle control, but where on the engine is that?

 

The aux air device is mounted under the inlet manifold...
