Hi Guys, thanks for your help here some great insights to check. I have a 2010 facelift V50 1.6Eco and have had almost every dodgy wiring issue going from steering lock reset etc. Over the last year have cleaned up all the relays, fuses, cem etc etc and all good. Last issue was throttle pedal one. Various codes pointing to dodgy connections. Took pedal off and cleaned up all contacts and buggered up the plastic bits using modern wd40 (crap) and pedal was no longer smooth but errors went away for a few months. i dont really use the car too much anyway so a few months here doesnt equate to thousands of miles, maybe a 1000 or so. Cant recall codes offhand at the mo but main issue was power reduction and engine service required. You could drive through these for a shortish distance and it would cure itself. But its back again on last trip as I slowed down in traffic, but again a few moments later it cleared itself.
I was going to get a used pedal 4M51-9F836-BK which seems the same as mine despite many differing vehicles using the same one. But I thought I should try your tip on checking voltage pedal to cem. And then it occurred to me lots of these silly problems can often be cured by a software update. Fords were notorious for it. What do you think? If so is there a way to establish what software version I have on the car and what software version is the latest? I guess the latest could be 5yrs old or more but its a good place to start, just ensure you have latest software update? If so how can it be done and what would the costs be ish?
If you think its software first I'll go for that, then the pedal wire to cem, then maybe another pedal and after that if it still happens Im stuffed. Cheers

as i said its never the pedal ,
you need to get a new plug shell for the throttle pedal and renew the terminals too , they have lost their springy grip on the pins , also the other end of the signal wire to the CEM put a new terminal repair wire on that too.
