#32: Re: Idle concern 206 gti Author: kandlbarrett, Location: SwindonPosted: Fri Jan 25, 2013 9:32 am ---- As previously described the AC puts an additional load on the engine so revs will drop lower and stepper motor will try to correct for that.
I could not say 100% that it will be stepper motor but am quite inclined to think so. Will your local scrappy let you try a second hand one and if it fixes it you pay if it doesn't you give it back?
I haven't re-read the whole thread but what checks have you done on MAP sensor or code reading?
Are you sure that the mounting area and hole that the stepper fit into are spotlessly clean.
#33: Re: Idle concern 206 gti Author: Jordy6969, Posted: Sun Jan 27, 2013 7:24 pm ---- Before I bought the car I checked the ECU for fault codes and it was all clear! I have cleaned the whole throttle body with the specified carb cleaner. I will have to ask the scrappy but I'm not sure if they will. Might have to just risk it, can't be too expensive from there!
What are the checks you can do regarding the map sensor?
Cheers for the help pal

It may be worth removing the MAP sensor and spraying with carb cleaner. It is delicate so no scrapping or scrubing please.
When cleaning the throttle body did you remove the ICV (stepper motor) and clean that and the location it fits into. When the ICV is removed also spray carb cleaner into the hole that the ICV mounts into.

To check the supply voltage disconnect MAP sensor with engine off. Switch on ignition and put a multimeter across terminals 2 and 3.The correct reading should be 5V
To check the operation, leave MAP sensor connected, switch on ignition and put a multimeter across terminals 1 and 2. the reading should be 4.4V
Start engine and leave at idle, check again across terminals 1 and 2. Correct reading is 1.3V
Rev engine in sharp bursts while checking voltage across terminals 1 and 2. It should read 4.4V briefly.
And some people don't think this site has enough technical information.
