Stop and Start Unavailable... Check Engine! TWO WARNING LIGHTS!?!? HELP!

2010 Punto EVO GP Problems:

I'm onto another problem with my Punto Evo - Power Steering was the most recent - But now, for what appears to be no clear reason, I am getting the message "Stop and Start Unavailable. Check Engine" message on my display.

The car has been working fine. I drove it for about 40 miles today, parked it up and up until this point the car was working as normal. No error. Nothing.

I return to my car, start it up and get a beep and the error message with accompanying warning lights.

Any ideas what this could possibly be?

I'll be ringing the garage tomorrow just hope that if anything needs doing in terms of parts, that's it's going to be covered until the third year of warranty.

Could be just the neutral switch needing recalibrated, takes 2 minutes.

Couldn't see that bringing on the EML though? I guess that you wont have any form of diagnostic equipment? What engine is it? 1.4 8v, 1.4 starjet or the 1.4 MAir?

Why not? Error P181D neutral switch callibration does bring on the engine (or should I say more correctly the EOBD) warning light, I see it almost on a daily basis.

What makes stop start non-functional? battery voltage - neutral switch - clutch switch are the most likely suspects.

Dependant on engine but lengthy startup on Multi-airs brings that up aswell. Mine done it before.

But I didn't think it would bring up "Check Engine" for the clutch switch or the neutral switch though but I suppose thats how fiat has programed them.

doesn't matter if light goes off and it self resets, error is still stored and calibration is easy to monitor.

Re: Stop and Start Unavailable... Check Engine! TWO WARNING LIGHTS!?!? HELP!

I've had 'stop start unavailable' and it seems to only happen when I have the heating on. However to be honest start stop is pretty useless in my car as I just hold the clutch in when stopped or turn the engine off in long delays on the motorway.

I've had 'check engine' before but afew blurts of the throttle pedal seemed to cure it. Came to the conclusion it was just a little bit of crap in the sensor.

Current message on the dash is 'possible ice on road' Stoopid weather.

Well mine is being quite good just now, usually get "Check Engine" and "Start/Stop unavailable" and comes out with P0470, need to get the 2nd sensor mapped out

It happens occasionally with my 500 as well, and although it will reset itself in time, the two warning lights annoying me.
So I went looking for a solution and found that turning the ignition key several times (about 6) in rapid succession without actually starting the engine will reset the system, although it can take a few tries...

Mine did this turned out to be the map sensor out of calibration. Seems any little thing can set this off and unfortunately fiat seem to be the ones who can suss out the problems
