ICV Techie Question

[Rob669]

I fitted a new idle control valve (ICV) today because my idling speed kept bouncing about between 1000 and 1500 ish rmp. I'd cleaned my old ICV a few times and just got sick at it not working 100%. But when I fitted a new ICV the revs went straight to 5000 rpm and stayed there! I took it out and compared it to the old ICV and saw that the valve was open in the new one and closed in the old one. So I forced the new valve to close and it seems fine.

But does it sound right - has anybody else had to do that when they fitted a new ICV?

It's a ph1 172.

Cheers, Rob660

You shouldn't have to no but if its works fine then I wouldn't worry about it. Probably took a knock in transit and got jammed wide open.

you have to have get it trained on the car. Or find a CLIP to succesfully calibrate it.

I must have got lucky then when I altered it by eye, it seems to be working now. Phew, thought I'd just blown 60 quid on the cost of the new ICV - and much more worried that it might indicate throttle body wear and another big cost.

Cheers

I will be doing this soon.

How do you calibrate the new ICV?

Probably not by using my flippin' great screwdriver method. I'm sure there's a correct way to do it. I'd be tempted to take it to a Renault specialist (independent specialist) who's got the right kit.

I just levered the inside bit upwards so it almost closed the gap. Touch wood, it does seem ok.
