idle control valve focus 1.6ti vct

[bigal83]

Where is the icv on my car?  I've been told it doesn't have one.

The idle is very lumpy at times and it cut out today when I pulled up to

to turn right. If it has one I suspect it needs a clean.

Thanks guys

Just thought... where is the temp. sensor, I have a new one too fit.

The 1.4/1.6 Duratec including the TI-VCT do not have an idle air control valve. On this type of engine the idle speed is fully controlled by the PCM. When idling the PCM continuously adjust the throttle plate position to obtain the most optimal idle RPM.

ok, thanks for that. I need to look elsewhere then.

When did you last service it? Have the spark plugs been changed recently?

[bigal83]

Just bought the car, but it was last serviced November  2015. I've got the oil and filter and it's going in

this weekend. As for the plugs I'm not sure. Still looking for the temp. sensor though.

depends on the idle speed which will be less than 800rpm standard

My idle speed went up to 1000 when I changed my ignition coil, but after 5 mins it goes to 900.

dash diagnostics will show a true reading its barely above 800rpm but shows 900 on the display with the to vct plugs and plug gaps perishing leads dirty throttle body vct issues collapsed hoses faulty accelerator sensor faulty gearbox sensor faulty temp sensor and a pcm upgrade required can all cause the issue without scanning live data you can throw money at it forever
