Cambelt snapped ! Replaced new valves head gasket etc etc etc! Now have engine management light on and apparently the fuel temperature sensor / air flow meter / coolant sensor / inlet mass sensor are all faulty ! Does anyone know if all these sensors could in down because of one fault ? The van was running fine before the belt snapped!

Our 1.4 8v Doblo recently had the cambelt replaced. For the next week or so the engine management light kept coming on.

A hero Dobloid on this forum told me to do a 'phonic wheel learn' to fix it (search on the forums for a description. Its all to do with the crank sensor). I was unsuccessful because it needs a clean (memory wiped) ECU to be successful. So the garage that did the cambelt change did the necessary.

I hope this helps.

Mine is 1.9 jtd ! Someone has suggested revving to 6000 rpm 3times to reset ? Because light is on it limits it to 3000 rpm ! I am beginning to think the best thing to do with this vehicle will upset most fiat owners / apart from those whose vehicle is giving then problems !

I've been told that disconnecting the battery and getting it well clear out of harms way, then touching the battery positive and negative terminals together clears any residue charge from the ECU to clear codes. Might be worth a shot.
Did you get a diagnostic scan done that suggested the listed faults?
If not, just as a guide to costs, my local Fiat main dealer quoted £70 for diagnostic scan compared to the £30 mark for a independant garage but probably usings 'unofficial' software.

Tried it ! Looks like main dealer will be taking my money !

why did the cambelt snap, was it over due needing changed?
