just found out that 2002 punto ecu units are on recall by Fiat Recall code 4679 and this will be replaced by official service centres free of charge. Fiat have recognised there is a problem with them.
You're right... didn't help. The IAW light still keeps coming on and the rev counter goes all over the place. Although it is getting progressively better the more I drive.
I reckon it's one of the sensors. The engine temp gauge has always been broken on this car (for years) so I reckon it could be the engine coolant sensor...would make sense as the car seems to be fine for the first 10 mintues from cold, then miss-fires more and more... at high revs it's fine, just horrible between 1500 and 3000.
Do you think replacing the engine coolant sensor would help?
... I don't really want to send it to a garage as everything is cost prohibitive for such a cheap car... I've spent £250 on this already - car's only worth £600 and ran perfectly until this happened.
hi could you help me i have a punto 1.2 2002 16valve,the fault code p0105 has been scanned:slayer::slayer: map sensor has been replaced still fault code came back,found a small air leak repaired still the fault code came back.what else could this be ecu????what punto you got?
OK the procedure you need to do is called phonic wheel learn.
Thanks for the advise mate, i had a problem after installing a 15bhp chip thing which i later found just pulls out the auto choke and wastes fuel and makes ur car run faster, but anyway the light is now off and the car is sorted after your advise cheers i was crapping it thinking ive broke my car.
P.S dont buy or use the 15 bhp chip/ box MODULE by CELOX it is bad for your car!!! and can be costing you more in the long run!!!
OK the procedure you need to do is called phonic wheel learn, and basically your friend is right except for a few details.
The engine must be up to temperature (75 degrees plus), and the engine needs to be revved rapidly above 5000 revs and allowed to rev down on its own. The easy way to do this is just to stab at the throttle pedal and release it, the engine revs need to come down on their own so as soon as shes reached 5000 revs remove your foot completely from the throttle. This needs to be done three times in a row and provided you have done this correctly the light will stop flashing, switch the engine off and leave the ignition off for the power latch period (60 seconds) before restarting.
Numanr DET.
Genius!
Dont know where you got the idea from, bu it works THANKS A LOT
The problem is that the ECU people will not warrant the ECU unless the coil packs are changed
this is a question for anyone that knows if i get a second hand replacement ecu with the same part no.do i need to recode it before fitting or will it work as a plug and play ...my daughters car is a 05 punto 1.2 8v sole and its been having problems for a week now we have spent 200 at the garage and they have replace the leads plugs and both coils twice now they saying it will cost another 300 -450 to replace the ecu ...there are second hand ones on e-bay for 60 and i am concerned we are throwing good money after bad and chasing a problem ...the car is throwing up a 0352 fault primary and secondary coil B fault and will only run on 3 or 2 pots .....any help would be great ....
