hi there
where did you get the codes from?
i don't see them on our list...
http://www.fordscorpio.co.uk/codes.htm
you've got a rare scorpio there. not many auto td's about.
not sure what engine management system it uses.

got the codes through my mates snap on solus p0725 is a generic code and the p1226 is ford (ids 2000?) the first saying engine rpm input-circuit malfunction, probable cause wiring,ckp/rpmsensor,ecm/pcm/tcm. the second said control sleeve malfunction.he has only just bought his diag kit and is still practising but he just shrugged his shoulders and said it might be a bad connection it might be a new sensor but he does not know how to test just diagnose but i have a good multimeter so if i know what to test and in what parameters i might be able to suss it out

hi there
iirc, the newer td's have 'fly by wire' throttles, so your first code might something to do with that. does it have a throttle position sensor?
the 2nd code might be something to do with the turbo/wastegate.
where abouts are you? i know of a good diesel engineering place in lanarkshire, if that's any good.
unless you can find out exactly what the codes are pointing to and also what parameters they should be at, then you'll be stumbling around in the dark.
i've no idea where to even look, bar taking it to an expert. the place i know of would run a diagnostic, tell you what's wrong and how much they would charge to fix it. most time's he takes the diagnostic charge off the final price.
hope this helps a bit.

hi there it is a fly by wire which someone has mentioned to me that it might just be the crankshaft sensor playing up i am based in birmingham and because i needed a car straight away for work i went out and bought a rover 825 sd today (the last one i had was just over 600k miles when i sold it) (ex taxi on its original vm engine)(i will only buy cars with vm engines ) so when the weather picks up i might have a look to repair the scorpio as they are much more comfortable than a rover but if someone comes along beforehand with £300 they can take it away as i am sure it is not much wrong as the engine has no funny noises and not belching out black smoke but is slow (probably suit a sunday driver) cheers kev

hi all i have now found what the codes actually mean p0725 is crank sensor and p1226 is fuel quantity adjuster position sensor so now all i have to do is work out how to test them and all the wiring but my gut feeling is pointing at crank sensor not giving a correct reading so bringing up the other code but i will keep you posted on how i get on ps just borrowed a ford factory workshop manual cd-rom very informative cheers kev
