My UK 2004 Focus TDCi is reporting error code $10 ECM P-0401 "exhaust gas
recirculation flow insufficient". It drives perfectly with no problem
apparent, good fuel economy (50 mpg) and no black smoke. The engine
management warning light came on about six months ago. I had the code reset
and the light went out and stayed out until a few weeks ago when the light
came on again. Yesterday I had the code reset again and the light is still
As the car drives perfectly is this likely to be caused by an intermittent
connector rather than a system fault?
Could anyone give me a clue as to which connector my be intermittent (and
where it is located on the car).
