any ideas as to where to go next with this?

you taken the battery off when you put the old one back on?

no andy,

but, the engine management light has now gone off. I have done nothing other than not drive it last night. Havent disconnected the battery either.

Looks like its fixed itself

Right the sensor he sold you are duff or not compatable

The eml will reset after three faultless restarts from memory

this is the one I used.

it does state it fits a 1.4 grande punto.

The item in picture has the little yellow bit on it (not sure if that is a resistor) but when it arrives it does not. Not sure if that's anything vital?

either way, if you know any sensor's that are 100% compatible i would appreciate it as my MOT is in march.

I found this one? http://www.shop4parts.co.uk/?name=store&op=Details&ProdID=6212&sku=15423

That little bit in the cage is a Thermosistor (guess what that is supposed to do) and correspond with the the fault code you have been getting i have one of their sensors in the garage i'll try and find it and grab a picture

(did you get them to send you a replacement as they do offer a

"Our Items are NOT reconditioned.

They are NOT refurbished.

They DO have a 12 month warranty"


Had a MAF sensor from another supplier for a Nissan Almera and it had a component missing (when comparing it to the original one) the replacement they sent had the missing bit and it worked no issue

yes andy i got another one sent out.

the replacement also had the thermistor missing.

the picture they use does represent a MAP sensor WITH the thermistor, iv had two both without so i cant decide if im super unlucky, or the one i purchased really does not come with the thermistor.

What you reckon?

this is the one i got for mine from them a couple of years ago..............

the thermasistor is black

Update 2:

Just refitted old map sensor, error still there. What's going on? obviously iv upset something whilst replacing it.

I cant help but notice the old sensor has an orange bit (looks like a resistor) whilst the new one doesnt?

Again, the original is now bringing up the error.

Thats what mine look like?

dont know if its the same as yours (thermistor is black maybe?)

Andy, I know im dragging this on, but if the EML is now out. Is there any way I can know the sensor is working correctly?

To save starting another thread, mine is also doing this now.

I thought the juddering was engine mounts, but reading this I may be mistaken.

This morning the car didn't start, normally it feels like it cuts out and then jumps in to life but not this time. It's only going to get worse from now on in I guess, so can anyone point me in the direction of the MAP sensor? It's £50 on shop4parts.

Seems to be ok!

Is there any difference between that and the 1.4 8v one?

I believe it says that it is applicable for 1.4s so I would think it should be ok. However it might be best to email them and ask.

no difference mate, its the one I used also.

Make sure you report back your results, it did absolutely diddlysquat for me

D4nny8oy If im honest, i dont even know. I took the car in with a rattling air bracket and they said it needed a new ECU, can't remember at all sorry mate.

The sensor I changed is certainly the map sensor and was replaced 3 times just to be sure.

my battery: varta 12v 40AH 300A

Any ideas?

Was it definately the EFI ECU? Is yours a 1.2 or 1.4?

The poor cold start issue was usually down to the air temp sensor reading high, not a map sensor fault (unless it's a model where the two were combined into a single sensor). This is where you really need to have had a proper diagnostic to see what the sensor readings were.

Battery spec sounds ok. Is it in good condition? (proper test, not just checking the voltage).

1.4 mate, i dont know what they changed, it was when i first got the car and back then I knew little about cars so never thought to ask.

does the diagnostic jjust plug into the socket that is used to read error codes?

I had it tested at halfords and I did attempt to manually charge it just in case, but obviously because it was charged it made no difference.

if you can help me here ill learn to do backflips because this is driving me nuts mate.

Fiat's Examiner and other diagnostic machines all use the same 16-pin diagnostic port. A code reader will tell you sod-all because often the ECU doesn't recognise the sensor as being faulty, so doesn't record an error.

A decent battery test will help. A battery can show as having 12volts, but next to no amps- so you can see how a basic multimeter voltage test across the two poles will tell you nothing. All Fiat Dealers (and other decent garages) should have a handheld machine for testing the battery condition (Midtronics, or similar IIRC).

I had one done at halfords (my girlfriend works there otherwise i'd avoid) and he said all is fine and gave me the ampere/voltage reading. Can't remember it though.

think it may be worth new battery anyway?
