(T) ESC & Hill Start Unavailable = Limp Mode

Been searching the forum for days now looking for an answer to my problem. I have a Punto 2017 1.2 petrol had it for 12 months (car went limp in traffic, there was no throttle response and I had to glide off the road to safety. The car will run for about 1 minute and then it triggers a check engine light and displays a message that the ESC & Hill Assist are unavailable, the engine starts to make a chugging sound and holds the revs around 1700RPM, throttle pedal is dead during this). I was really pleased i had recovery. It has been in the local garage express fit auto centre, they said it had a MAF fault code but the car does not have a MAF sensor fitted. so has the car was now running ok they said just drive it and see how it goes.
Sorry for this being long winded but any help would be very much appreciated.

So if it’s working ok at the moment I might be tempted to just leave it and hope the problem doesn’t come back, you could take it to another garage and ask them to check the fault codes but if the previous garage cleared them and the problem is now gone then it might just be a waste of £50 to have someone plug it in and tell you there is nothing wrong.

I’m no expert here when it comes to the newest petrol puntos but I’m 100% certain there should be some sort of air intake sensor there which makes me suspicious of you being told there is no MAF. It could be a detected fault cause the car to limp but with the codes now cleared the fault has gone away, with the ‘fault’ being an erroneous fault code. You could spend a lot of time chasing your tail on this when all you really need to do is drive it to see if the fault comes back.

The 1.2 and 1.4 petrol fire engines genuinely have no maf sensor just a map Sensor


My guess is codes were read a a system that dosnt work very well with fiat cars

As I said my feeling is there would be some intake air sensor so the fault was with the person using the machine and feeding back what was wrong, not sure if that was fully clear from my last post.

Thanks guys the garage did also say they reset the fault code. Should of asked what it was, never mind. Since then I have done some searching and found out the car does not have a MAF sensor fitted but does have a MAP sensor fitted. I have removed it and it was covered in gung so cleaned it up so I will just have to wait and see.
Cheers all.
