What year car made?
Which engine fitted?
What code reader are you using to get a code starting with p that is 6 digits long?

All previous posts were about a Stilo..



Googling sometimes helps..
but the code does look odd

Plus what type of gear Box is fitted?

sorry forgot to put details,its punto eco 2010 garage gave me the code. sorted it myself it was the battery was below 80 percent charged it up everything back working engine management light gone and stop start now working thanks for looking

Have you put a voltmeter on the battery? If so how many volts showing?

If the battery is quite old it has to be the number one suspect and may just need to be replaced - if so then, with stop/start it's going to be either and EFB or AGM type, most likely EFB given the age of the car (which is good as it's quite a bit cheaper) Don't try to cut corners by fitting one of the old simple lead acid type batteries. If the battery is quite new then get it professionally checked and if it's Ok you've likely got a parasitic drain going on somewhere.

It has to be said though that Fiat's stop/start system seems to have a mind of it's own and there are lots of posts from people saying their's doesn't work. My boy's Punto almost never worked since he bought it some 4 to 5 years ago (2012 Punto 1.4 Easy). A few months ago his battery packed in altogether so we bought a new EFB for it and the stop/start has worked most of the time since then!

got another diognostic done says gear box recognition position switch problem any thoughts thanks

anyone know where i might get gear box recognition position switch for my 2010 punto thanks

I'm a bit troubled by your tribulations here. If the car was an automatic then that diagnosis might make more sense, but I think you have a manual gearbox? I'm not so familiar with your actual model, does it have a "gear selected" indicator on the dash display? might be relevant?

The most obvious place to start is to ask you what diagnostic gear is being used to obtain this code? Your fault code P1850 - lets forget about the last 2 digits just now - starts with a P so this means it's a powertrain code and the next digit is a 1. This means it's a manufacturer specific code. If it had been the more usually encountered 0 then it's a generic code. I would find it more easy to accept the accuracy of a generic code when scanned with a non manufacturer specific scan tool than a manufacturer specific code. The genuine factory scan tool (or, in my experience Multiecuscan) should give you a result which you can have confidence in. There are many posts on here where people have been mislead by codes obtained using generic scan tools. If you are not all that familiar with DTCs this might help: https://www.obdadvisor.com/most-popular-obd2-codes/ Don't be put off by the fact it refers to OBD2 codes because our EOBD codes are virtually identical so the info given here is still relevant to us. By the way the numbers after those first four numerical digits are most probably to help in narrowing down the options (manufacturer specific again?)

So, can you tell us what the equipment is that is being used to scan your car? If it's not Fiat specific I think your next step must be to find someone with MES (there's a thread on here of people with it who are prepared to help) or get it scanned by someone with official Fiat equipment, then you can have some confidence that it's not leading you off in the wrong direction.

PS Can I guess you meant 2010 Punto EVO (not ECO?) - Unlike many, I actually really like the styling of the EVO!

thanks for your reply,i got a mobile diognostic company to come to mine they had some very good equipment,he checked the code and it came back gearbox recognition position switch ive been trying all day to find a replacement but had no luck so far thanks for any help you can give

Just replied to your PM jimbo. Hope I may have some info for you after talking with the Harrisons next week. I'll post anything of interest to us all here if I learn anything useful

Please tell us what type of gearbox you have auto or manual, it will help us help you.

Neutral position switch is often called gear position switch. Try looking for neutral position switch.

Plus try looking up p1850

Just come across this which I think pretty much covers it - albeit related to an Alfa! https://www.alfaowner.com/threads/giulietta-p1850-fault-code.1134601/ Very much doubt if my Panda has one? - I hope!

This one is continuing to intrigue me. Having found this definition yesterday and posted it here without giving it much thought, I've been thinking that I've not come across any such device on my boy's 2012 Punto (1.4 8 valve) so I've been continuing to research it starting with my Haynes manual - which makes no reference to it. When you search for definitions for this 1850 code it frequently comes up as a band solenoid problem on a conventional epicyclic automatic box and, much less frequently as the gear position switch.

On an automatic I can absolutely understand the need for such a sensor but on a manual transmission? Anyone know if our cars have such a position switch?

Sorry, I had intended to finish off my last post by saying that I think this car still needs to be diagnosed with either MES or Fiat dealer tool to be confident of the diagnosis.

D'yu know folks, we still don't know if this is an auto box? Do we? Got to be hasn't it?

Said I'd talk to the wee Fiat garage today, and I just did! They were very busy so couldn't spare me much time but did say that the car is almost definitely an automatic if it has such a switch/sensor and that they don't "fiddle" with the automatics because less than half a mile away there is an independent automatic gearbox workshop and they simply run any autos with problems round to them.

So, sorry, not much further forward. Please do let us know how things pan out won't you.
