D24TIC - what is this switch

DLM48 · Dec 11th, 2007, 18:48

looking under the bonnet today i noticed a micro switch attached to the IP after wiggling the throttle i noticed it did nothing then i realised the actuator arm was missing - so what is the function of this switch

thanks in anticipation

Don't know either - the whole switch has been removed from my engine. I do seem to remember JOR saying that the switch opens as soon as the throttle is pressed, but what the purpose is I haven't a clue.

David ,
The switch is part---or was for the EGR system most likely now plug off , if you have to refit or repair for legal requirements let me know .
Your new car looks as good as you would find in sunny California , nice buy .

Out of interest, I just checked my '93 D24 TIC and I have the micro switch, complete with actuater arm, never noticed it before and didn't have a clue what it did until I read the posts here.

Look at the exhaust manifold David and you will see a pipe whose other end connects with the inlet manifold, there is a picture of the inlet end on the tfb thread 'newbie with a couple of questions'. If you take off this pie you are likely to find a blanking piece obstructing one or both ends. I'm not sure where you would acquire one if not.
You can also disconnect the vacuum connector as shown.
