Saludos from Chile, thx for you guide, I have same problem the wires are cut when I desarmed 😢

[@ItaliaAutos]

Hi. You can re join them but sensor normally fails too

[@noks9827]

Yes, I was able to solder them and clear the error code, so far it hasn't failed.

[@eben6094]

Great video, but out of curiosity, does anyone know what is that "deep" noise coming from under the car?

[@richardjohnson3463]

Top man!

[@ItaliaAutos]

Thanks

[@Igizeh]

Thank you for this detailed video! Do you know if that applies to TCT version as well? If yes, what are the differences?

[@ItaliaAutos]

No I don't think so

[@Igizeh]

@@ItaliaAutos thank you!

[@TheMattia27c]

Disabling start and stop, this error can be bypassed ?

[@rafalkwiatkowski1616]

Hi,mate I have replaced this sensor but error still come back sometimes. Previous owner said that he started to have to problem after battery change? What can i check ?

[@anthonyseales3016]

Stupid question what’s the sensor called or part number thanks in advance

[@rytis11221]

I have the same engine light and start&stop but it only comes on after i put my car in 6th gear, the car be stationary just on ignition u put it in 6th and the engine light comes on lol. Would this be the same sensor problem? My error code is P130662

[@ItaliaAutos]

Something that will need to be looked at as it's just guessing without

[@chacale19]

hello your repair applies to the mito Quadrifoglio 170cv I have the same problem this sensor is the same for my mito? thanks in advance.

[@ItaliaAutos]

Yes

[@chacale19]

ok thank you do you think it's the same sensor as giulietta's? THANKS

[@ItaliaAutos]

There are 2 types fit pretty much the same

[@chacale19]

@@ItaliaAutos ok you don't know the reference for the bike because I can't find it on the internet? thanks in advance.

[@FrankishKnight]

Last time I had a similar issue, I just removed the exhaust, it was a 5 minute job, putting it back wasn't hard either. I don't know about Guilietta but is there any reason you didn't recommend people removing the exhaust?

[@ItaliaAutos]

I should of done really would of made better viewing. But as you can see you don't need to.

[@FrankishKnight]

@@ItaliaAutos okay got it, video wasn't bad it just looked like a pain in the butt. If you are doing this on your driveway, removing the exhaust makes the job 10x easier. Even for you if you removed the exhaust, you would save your energy for the next customers car, and it wouldn't take much longer I think, but hey it's just my uneducated guess.

[@paula200]

Wouldn't it make life slightly easier to just pop that exhaust flange and give a little more room to work? Maybe you don't because the bolts always break?

[@ItaliaAutos]

Yes it would but 9 times out of ten the bolts snap.

[@stephenredfern7536]

How much would you charge for this repair?

[@ItaliaAutos]

around 2 hours of labour on this one

[@JavenarchX]

Bloody hell.... thoracic surgery looks easier

[@dahuseventy]

Love the Giulietta vids. Warranty expired last month for me so I would like to know how to fix common problems. Thanks mate!

[@zzhughesd]

I’ve a Punto Evo neil with Gear Posi sensor throwing a MIL and a Stop Start. DTC 1850. Never come across a gear selector under the gear stick gaitor before

[@lukaskristensen5356]

You're videos are great. You make it possible to actually maintain and repair these amazing cars, whilst on a budget, which makes it possible for many more people to actually buy these cars and keep the brand alive. Keep up the good work.

[@marko3296]

Had to leave my Alfa GT alone at the Airport for 6 weeks. Cant wait to see her again :)

[@sup3rbosseur]

How can u leave your car at airport, 100% stolen or broken

[@peterboot7120]

Put a class 5 alarm on it drive my 147 2.0 from 2006 always I a Gerage with Camera's she looks like a New one😍😒

[@dingodesertdog]

Excellent guide, thank you! Did mine on ramps, remember the safety specs to avoid getting bits of crud in your eyes! Just one broken wire on mine so added a new bit, soldered and heat shrunk, working perfectly, £300 saved.

[@ItaliaAutos]

Glad it was helpful

[@danieldan1057]

Hi. Can anyone help me change this sensor? In Crawley, West Sussex area? I have the part. Cheers.

[@ItaliaAutos]

Have a drive up

[@uKBaZ84]

Hi, I have this issue with my fiat punto evo 2010. Would it be a similar way to fix it? Thanks

[@ItaliaAutos]

Yes

[@Lupo116]

Thanks, mine had a broken wire. Did it in no time after watching your video. 👍🔧

[@mrcha84]

I have a question.Can this fault P081D(faulty or broken gear position sensor) cause MAF faulty code P0101.I have changed the MAF,bought and installed a brand new one,but from time to time i get MIL light on,indicating fault on gear position sensor and MAF fault code...i have a Giulietta 2.0 jtdm

[@nassimeazdad5025]

Hi dear, i have same fault (P081D) what i have to replace pls?

[@deebo007]

I did this on mine lying on my drive with the car on ramps. It helps if you bolt the gear lever mechanism back in place whilst changing the sensor, this saved me a load of hassle.

[@davidfirth8371]

Awesome stuff, although my g doesn't throw the engine code up it only throws the stop start not working display

[@peterboot7120]

Only had my Termostaat last weak now she drive perfect my 2.0😀💪👍

Any idea on how to disable this stop/ start system permanently ? its driving me nuts...

[@ItaliaAutos]

only to map it out.

[@andrewyeo2353]

Thanks for sharing. I have a mito and my stop start wouldn't work after cold mornings disconnected and reconnect battery all would be well replaced battery and all is fixed. Does fiat ecuscan software work on these alfa?

Yes it work.

Hi can someone help me plz my Alfa Romeo 159 jtdm 1.9 16v has ABS ASR VDC AND HILL HOLDER Unvailable for no reason when i was driving, i can start and drive but i have no security

[@ThePhoenixEvils]

Bonjour Vous ne montré pas la position du capteur sur le cable :( je ne sais pas a quelle endroit clips le plastique jaune :/ a quelle distance je doit refermer le clips jaune sur le cable avec les lignes crantée ? Svpppp merci :)

[@rashadsindi5059]

My own would start if the engine is cold and then would misfire and stall for no apparent reason. However, if I drive it on a highway the car drives perfectly. When the issue happens I get a check engine light and the code is P2292.21. I replaced the fuel injectors control pressure sensor located on fuel injector rail, but it didn’t solve it. I checked both fuel pumps and proper pressure, fuel delivery are both present. Do you think you can guide me?

[@terrypayne8040]

I have a 12 plate giulietta automatic 94k been an excellent car , first fault ever to come up is this one. I had to drive 300 miles home very concerned . the car seemed to faulter whilst going up hill not much just a little bit of missing then carry on fine, would this be due to this stop start sensor. ???. thank you

[@peterboot7120]

Pff good Job! ,happy that my 147 2006 is simpeler to Fix 👍

I was going to tackle this myself but this looks like a right faff without the car being up in the air! Plus my knees ain't what they used to be! Thanks for the insight!!

[@DERxTECHNIKER]

I have the same fault, but on my display it shows the correct gears. How can this be? Or are there other things that can cause this error?

[@marcsima3894]

Hello, I have same issue on my Giulietta but it's other Engine 1.6 Jtdm 105hp. It's possible to be the same problem? Code P1850-15 it's universal for this issue or depends on the specific Engine?

[@ItaliaAutos]

possible

[@felmi5032]

Can you help me again please:) I want to change the steering servo oil (Alfa Brera 2,4) from atf to the green liqui moly. Can i just dismount the pipes and start steering (while the engine is running) to flush the circuit. Or is it a bad idea because the pump will run dry? + How can i deaerate/ exaust the air from the system afterwards. Thank you very much for your great videos and your support.

Hi Neil, hey at 11-37 when you under the car there was a buzzing noise in the background. My 156 v6 makes this noise if I have the ignition on and seems to come from the intake area. Do you know what it is and will having the ignition on for any time potentially break whatever is buzzing? Thanks Steve, Sydney Australia

its prob just the vacuum for the turbo

If you removed the exhaust you would have saved your gloves

Great video again, never really been a big fan of the brand to be bair but they seem to be growing on me a bit, the 159 especially. 👍

Ive had this problem multiple times and fed up paying to fix it. can we disable this?

might be something a good remap company can map out.

Hi, same fault here!!! Is it the same spare part and procedure for the TCT gearbox?

[@ItaliaAutos]

never done one on a TCT but id imagine not.

[@newtothisthing]

Hello. This fault appeared on my Guilietta recently. I never use the start/stop option so it doesn't bother me. What does bother me is that now the DNA is not working. Will I have to replace the sensor in order for the DNA to work again or is there another way around it ?

[@ItaliaAutos]

Nope. Ecu shuts it off.

[@newtothisthing]

@@ItaliaAutos I managed to replace the sensor with a new one by following your instructions on this video. Thanks a mil. It's my first attempt at anything like this and couldn't have done it without you!

How do you disable Start/Stop forever? I hate it!

[@ItaliaAutos]

Don't think you can. Maybe talk to a remap company.

[@petrwowra4097]

You can do it in Multiecuscan. Just disable start-stop module in proxy alignment menu. It can be enabled back if you need to.

Hi, i had a few questions about my giulietta that i was wondering if you could help with? Firstly, once in a blue moon i would get a p1064 error code and then shortly after, dissapears. Do you know the cause and solution of this? Also, i wanted to know if there was a way i could bring a cable from under the car into the boot? Is there an existing hole or grommet? (I originally tried bringing a power cable from the engine bay into the cabin but couldnt find a suitable firewall so have resorted to bringing the power cable inderneath the car, into the boot).
