Technical Help buying a used PAS motor
Hi & welcome to FF vkobi :wave:
What punto do you have? What year is?
I suspect its not a mk1 as they have hydraulic PAS.

Hi,
get the fault codes read.. see what component in the steering system is logging faults,
then look in the Punto 2/B section for further info,

hi & thnks blu73 & varesecrazy.this prob has gon on 4 som time.charging the batt used 2 put it rt but not now.im convinced its the motor.matching it is the prblem.iv spoken 2 four difrent mechs & they all hav difrent ideas on whats reqd.although they agree its the motor thats gone.
Mmmm, seems a bit weird that a motor could give you issue and charging the battery fix it temporarily. Sounds way more likely to me that the battery is dying. Before you go buy parts I suggest that you
1. check the battery terminals, as in clean them up to ensure the battery posts and cables are both nice and clean to give a good contact.
2. Get you battery tested, places like halfords and many garages will test it for free - they can read 12v and be buggered still - when they use a tester they apply a large current draw to the battery and see how much the voltage drops, shouldn't drop very much but if its on its last legs it will drop quite alot. And PAS is just about the biggest current draw the battery will ever see bar the starter motor. Its pretty common for battery dying to manifest as PAS issues not just on punto's, just on cars with electric PAS in general its usually the first sign of a bad battery.
If you still have issue when its certain the battery is ok then look at messing with changing actual PAS, its a big job and will cost a fair bit if you are not doing the work yourself.
And yes, 2001 is a mk2 punto - i will move this post to the mk2 section in a moment for you

If the battery is good, changing the PAS motor is fairly simple.once the bottom steering column shroud is off the motor is accessible. Last time i changed one it took me about an hour.
However if you get another PAS Motor you need to make sure it is from a Mk2 with relays and not a relayless motor from a Mk2/B as the later motor will not work on Mk2 due to the CanBus

thnks evbdy but yor misn th point.th mechanics of th job arnt a prob.doin it mysel.battery fine.matchin th motor is my prob.one guy sed any motor wil do.anothr sed th ful column had2 b chngd.anothr that th motor & ecu had 2b chngd.anothr that certain nos.on motr mus match on replacement.wot nos.if any mus match.photos ( 2 )show nos.which of these mus match on replacement motor.ther r 2 barcode lables on motr.th smaller lable has 2 nos.a service part no.26087468 & anothr 68 106325383.th larger lable 4 nos.from th top theyr REV 049.26074600. 0123203103. 0202034200350.which of these mus match on replacement motor.
we aren't missing the point at all, just trying to help. What you described sounds more like a battery issue so was just telling you to make absolutely certain its not just the battery before you change the PAS. Cause if you change it and still have the prob that would be a massive waste of time and money...
As for what you need to buy if you do replace it.. You can remove the motor from the column and i believe the motor and ecu are a matching pair - i would buy a motor and ecu off ebay if it were me - generally they are 30-40 for the pair from what i have seen. My mum had exactly this issue once though, her local garage who are nice chaps and certainly were not trying to swindle her said it needed a new motor, they swapped out the motor and ecu and the issue persisted. I chucked in battery from my car and cleaned the earths while i was visiting her and low and behold it worked, so just bought a new battery and that was that.
So I was saying to get the battery tested cause you can't just trust that someone has checked these things even if you know they are good sound people - people make mistakes, they probably do know all this but they may have forgot or something, these things happen.

I second blu73. Voltage problems are the root cause of a lot of power steering issues. Get the battery checked out and then check the terminals, especially the earths on the negative terminal including the small one that piggybacks on to the main earth cable. Check the power supply plug to the p/s under the steering wheel. This can have corrosion on the pins.
To the best of my knowledge there are relay motors and non relay motors. The change was about 03. Ours is 01 and is a relay type. Relays are the next biggest problem with the older cars.
A code read did not indicate a torque sensor failure but a relay problem, code 117 iirc. The relays are less than a tenner for the pair and are easy enough to replace if you are handy with a soldering iron. A TV repair guy could do it eyes closed.
Used motors are a lottery as the relays could be in trouble already.
Replacing the column should be a last resort and only if the torque sensors are dead. I have seen someone replace them but for the cost of a re-manufactured column it not worth the hassle.

As someone already said, we didn't miss the point.
There are 2 PAS motors for the Punto.
Mk2 has a slightly less powerful motor with 2 Relays on it, this is the one you need for a 2001 Punto which is Mk2.
Mk2/B has a more powerful PAS motor without relays BUT it will not work on the earlier MK2 due to Mk2/B having CANBUS, Not 100% sure but i think Mk3 also uses the same motor ?
As others have pointed out the PAS motor and ECU are available on Ebay, as are the relays.
Changing the motor is straightforward.
BUT i also agree with what the others have said, make sure the Battery and terminals are good before going to the expense of changing the motor.

I really can't be bothered trying to put the effort I to reading text speak posts.
I believe you are missing some B's
I was...i spotted it after i posted and edited :bang:...bloody B's

When I changed my PAS Motor on the column, I just matched the serial number printed on the silver sticker and swapped them over.
I didn't swap any ECU and it worked (and still does) fine.
Not saying that's the correct way, but its what I did.

serials dont need to match, you just need to get pas motor from car that has steering column sensor cable color, yours is 2001 so its probably blue color
