#1: Terminals on a 206 Author: Jordy6969, Posted: Thu Aug 08, 2013 2:50 pm ---- I've been advised to carry out a test to check if my map sensor is shot. Part of this test is to check the voltage with a multimeter across 3 terminals with different variables. However I don't know where these 3 terminals are on a 206....
I dunno if this is common sense but I've searched and can't find my answer!
If someone could let me know I can quickly carry out this test and find out the cause of my idling problem

Has it had any head work recently?
#3: Re: Terminals on a 206 Author: Jordy6969, Posted: Thu Aug 08, 2013 3:15 pm ---- That sounds expensive tbh. The multimeter solution appears easier. Someone must know where these terminals are!
Nah no head work I don't think as no receipts from past owners, been advised that it might also be the ICV but concerned that it idles completely fine when AC is on and when engine is cold. I have a rough idle after 5-10mins driving and with without AC on...

Then test it on those. I can put up more detailed information when I get home.
Personally when anything idle wise is concerned, I would make sure it's 100% not the ICV first.
#5: Re: Terminals on a 206 Author: Jordy6969, Posted: Fri Aug 09, 2013 2:30 am ---- When you say sensor do you mean the map sensor or idle control valve sensor or just mean in general.
Any tests to check if its the ICV other than just buying another one lol
Thanks for the insight mate!

I've based this on a normal GTI.
Checking the ICV-
Disconnect the plug, if you can't get to the pins then disconnect the valve off the throttle body so you can hold it in your hands.
Measure the resistance over A + D and B + C. Both should be between 48 and 62 ohms.
I can get information on the MAP sensor if you want, but you need to check with the engine running. Apparently there are terminals you can use without unplugging it but I don't know of them off the top of my head.
#8: Re: Terminals on a 206 Author: Jordy6969, Posted: Tue Aug 13, 2013 6:19 pm ---- So disconnect the plug from the ICV and put a multimeter across the stated terminals ye? Or put a multimeter across the terminals on the ICV?
#9: Re: Terminals on a 206 Author: Harry, Location: StaffordPosted: Wed Aug 14, 2013 5:14 am ---- The ICV, you are assuming there is correct power and earth signals so you are testing the actual sensor.
#10: Re: Terminals on a 206 Author: Jordy6969, Posted: Wed Aug 14, 2013 5:23 am ---- Ok cheers! So will there still be a voltage running through the ICV even though the plug is disconnected?
#11: Re: Terminals on a 206 Author: Harry, Location: StaffordPosted: Wed Aug 14, 2013 6:04 am ---- The multimeter itself will provide the voltage, completing the continuity.
#12: Re: Terminals on a 206 Author: Jordy6969, Posted: Wed Aug 14, 2013 10:27 am ---- Ok thanks for the information pal.
If the resistance isn't between these numbers it's an indication of it being at fault?
#13: Re: Terminals on a 206 Author: Harry, Location: StaffordPosted: Wed Aug 14, 2013 3:22 pm ---- Yes, it doesn't guarantee that it is fine if the values are correct but if they are well out then it can be assumed that it is functioning correctly.
