Ford Mondeo 2.0 2005 - Idle hangs at 1400 rpm #

Posted by Paul Howd on August 23, 2009, 10:41 am

Year of Manufacture *: 05
Engine Code or Type *: 2.0
( Optional ) Scanner used: Multiscan

Idle speed hangs at about 1400 for a few seconds before dropping back.

When first called out I though "Aha! I know what this is"

But, throttle pot OP seems OK. road speed sensor seems OK and the ISCV does not appear to be sticking (The %age opening demand registered by the scan tool shows that the ECU is actually holding the valve open rather than that the valve is sticking open)

Oh, and there are no fault codes logged.

Are there software issues with these before I start digging deeper

Hi Paul,

Dirty throttle-body/plate?

Power steering pressure switch / wiring?
Open circuit raises rpm on some fords, HTH, Neil

Vin number means nothing to me.

Engine size? year?

its a 2.0 litre and year 2005 from the details in the 1st post.

I've got an 02 1.8 with similar faults but very difficult to actually have the car when it plays up.

have you reset adoptions, are the throttle volts and the ratch volts the same at tickover. ray
