#1: 1.1 206 W Plate Reving On Its Own... Author: adz2k3, Location: United KingdomPosted: Fri Aug 12, 2011 1:17 pm ---- Hi there guys & girls, new to the French sceen...
Basically ive just bought a 206 1.1 LX Had it a month been lovly, no problems.. but this evening.. It was reving on its own to around 3-4k without touching the throttle....
And seems to have drunk quite a bit of petrol as well.
Its only every now and again it does it... So far ive cleaned the butterfly valve on the throttle. As i fort it may of been that sticking.
Any ideas or pointers would be greatly appriciated.
Many Thanks!
Adz

#3: Re: 1.1 206 W Plate Reving On Its Own... Author: adz2k3, Location: United KingdomPosted: Fri Aug 12, 2011 1:29 pm ---- Sorry to sound silly... Is that on the tb bit at top of the engine? How do they come of? And clean with brake cleaner?
Thanks once again!

#5: Re: 1.1 206 W Plate Reving On Its Own... Author: adz2k3, Location: United KingdomPosted: Fri Aug 12, 2011 1:52 pm ---- Hi, i did have a look in there, and all i can see is things about anti freeze and coolent and oil advice etc.
#6: Re: 1.1 206 W Plate Reving On Its Own... Author: Deckchair5, Location: Bath UKPosted: Fri Aug 12, 2011 2:17 pm ---- Have a look on eBay and you'll find pictures of 206 stepper motors
But the fact your engine is revving up to 4k seemingly on its own then it might well be your MAP sensor at fault which tells the ECU how much air it believes the engine is taking in and the ECU adjusts the fuel to suit that airflow. So the fact you're also burning fuel might point more to the MAP as the idle stepper motor only comes in to play at idle rpm
Even then there may be nothing wrong with your MAP sensor and may be a simple poor contact there. Easy to spot if you have an OBD interface giving you live engine running data but a first step might be to disconnect the MAP sensor and spray the connections there with electrical contact cleaner (nothing else), let it dry and then give it a try
Sometimes you need to reset the ECU by disconnecting the battery for an hour or so and then it recalibrates what it sees as the "new" MAP sensor

#8: Re: 1.1 206 W Plate Reving On Its Own... Author: adz2k3, Location: United KingdomPosted: Fri Aug 12, 2011 3:15 pm ---- Is the map sensor underneath on that tb bit? like before it enters the butterfly valve bit?
To reset the ecu.. Isit a case of just leaving the battery disconnected for a hour and connecting back on.. then job done kind of thing?
Thanks

#11: Re: 1.1 206 W Plate Reving On Its Own... Author: adz2k3, Location: United KingdomPosted: Fri Aug 12, 2011 5:05 pm ---- That battery thing sounds bit technical to me, will it muck it up if i dont do it correct? or could i start again?
Thanks

You disconnect the battery negative, you wait an hour or so, you reconnect it again. Maybe it is a bit technical
Try your stepper motor first though
#13: Re: 1.1 206 W Plate Reving On Its Own... Author: adz2k3, Location: United KingdomPosted: Sat Aug 13, 2011 2:34 pm ---- Oh right, didnt realise it was like that lol... I read through that post thing and it was saying about holding this button, putting headlights on etc.. lol.
And the stepper motor?? what bit is that sorry.
#14: Re: 1.1 206 W Plate Reving On Its Own... Author: adzar, Location: UKPosted: Sat Aug 13, 2011 4:12 pm ---- From what I understand, you should follow the procedure for battery disconnection 'whenever a vehicle battery has to be disconnected' as described in that topic. And it's not really that complicated - just read through it first so you know what you're doing.
#15: Re: 1.1 206 W Plate Reving On Its Own... Author: Ash, Location: Running from Ant and Lee and Adam...........Posted: Sat Aug 13, 2011 4:58 pm ---- Is the battery in good condition?
#16: Re: 1.1 206 W Plate Reving On Its Own... Author: Deckchair5, Location: Bath UKPosted: Sun Aug 14, 2011 2:22 am ---- Stepper motor is around the back side of the inlet control valve. Find where the throttle cable attaches to the ICV and then look around the back of that. It's just held in with two bolts. Remove it and clean the valve end
Look on eBay for stepper motor picture so you know what you are looking for
Sign up to Peugeot Servicebox, (google it) it's free and will give you lots of diagrams and component locations specifically for your car
#17: Re: 1.1 206 W Plate Reving On Its Own... Author: adz2k3, Location: United KingdomPosted: Sun Aug 14, 2011 5:55 am ---- Hi, Im assuming the batterys fine on the car, it starts straight away, its only done it once since this 1st post i put up the other day...
Yeah i know the "stepper motor" as the ICV on other cars lol.
Will have a look into it, can you take them of to clean them?
Thanks once again guys!
#18: Re: 1.1 206 W Plate Reving On Its Own... Author: Deckchair5, Location: Bath UKPosted: Sun Aug 14, 2011 6:30 am ---- Don't take the ICV off, the stepper motor is just an attachment, a small part of the ICV assembly.
Item 4. Just two bolts and it's out
#19: Re: 1.1 206 W Plate Reving On Its Own... Author: adz2k3, Location: United KingdomPosted: Mon Aug 15, 2011 3:39 pm ---- many thanks
#20: Re: 1.1 206 W Plate Reving On Its Own... Author: adz2k3, Location: United KingdomPosted: Sat Aug 20, 2011 11:35 am ---- Well... Today we took the complete throttle body of... cleaned it right out, and the same with the stepper motor/icv...
We pluged it into a computer.. for it to say everything is working as it should... all bar the CTS coolent temp sensor... would this make it struggle to start, and rev like it does.
The computer was saying the cts temp was -40degrees...
Thanks for your input once again.
#21: Re: 1.1 206 W Plate Reving On Its Own... Author: Deckchair5, Location: Bath UKPosted: Sat Aug 20, 2011 12:17 pm ---- all bar the CTS coolent temp sensor... would this make it struggle to start, and rev like it does.

Yes, very much so and that's no good, that's a default extreme low temp and as low as it goes. Sounds like it's open circuit. Disconnect the ETS and spray the contacts with electrical contact cleaner (nothing else) as maybe they have become tarnished
You could check the resistance across the ETS terminals and see if it lies within this chart. If it does then the ECU isn't receiving the message
#22: Re: 1.1 206 W Plate Reving On Its Own... Author: adz2k3, Location: United KingdomPosted: Sat Aug 20, 2011 12:30 pm ---- To be honest, i think i will just get a new one for the cost of £10 or something at my local motor factors. Just didnt have enough time to get that today as they had shut.
So -40 degrees isnt good, and would make it do the hole revving and struggle to start thing?
Thanks
#23: Re: 1.1 206 W Plate Reving On Its Own... Author: Deckchair5, Location: Bath UKPosted: Sat Aug 20, 2011 1:22 pm ---- Oh yes, the ETS is a major player in good starting and engine idling
#24: Re: 1.1 206 W Plate Reving On Its Own... Author: adz2k3, Location: United KingdomPosted: Sat Aug 20, 2011 1:38 pm ---- brilliant, just want to say thanks for your help and everyone elses, hopefully it will solve the problem and i can have some french fail free driving lol!
Cheers
#25: Re: 1.1 206 W Plate Reving On Its Own... Author: adz2k3, Location: United KingdomPosted: Fri Aug 26, 2011 4:19 pm ---- The CTS has seemed to solve the revving problem and is now reading 70ish degrees...
Cheers guys!
#26: Re: 1.1 206 W Plate Reving On Its Own... Author: Deckchair5, Location: Bath UKPosted: Sat Aug 27, 2011 12:06 am ---- Excellent! Well done!
#27: Re: 1.1 206 W Plate Reving On Its Own... Author: galaxly, Location: Leicester, UKPosted: Sun Aug 28, 2011 11:02 am ---- Hi Guys,
It seems like the ETS was the solution for the revving and starting issue. As I have the exact same problem on my 206 1.1 (V REG) Can you tell me what exactly the ETS is or stands for so as to try and have mine replaced?
