Hi guys!
couldn't find any post similar




I got some uncommon power steering problems, I'd suspect a weak battery, poor ground connections or bad alternator, but these are OK. (sorry can't post link to previous thread)


The issue are simply, when i turn on the ignition or just after i start the engine, the power steering warning sign appear.
BUT i haven't experienced any actual problems with the power steering.


The other day i found out that when the steering wheel at turned slightly to the right, the warning sign will not appear, but if the steering wheel are in any other directions the warning lights will come on... But the freaking power steering runs perfectly!


Somebody experienced this issue before, or do you know what the problem are?

hi

i have the same issue, probably since one year ago. At my case it is a steering wheel angle sensor failure, don't affect steering power. Only happens at start and with a slight turn on the wheel the warning light will come off.

my GP isn´t eqquipped with ESP, so i can´t notice any other problem beside the warning light.

Hi! Ntrindade

Very Interesting.

Did you find a solution, or just living with it?

I'd did some research on angel sensors, seem like it should be calibrated when the steering rack are changed,
which was is in my car just before i bought it.

hello,

i tried calibrate it with "Multiecuscan" software some time ago, but I was no lucky with it. Maybe i will check it again soon.
but it throws the errors belows;

C1008 - Position sensor calibration
The fault is intermittent. Clear fault codes, and observe for future appearance of the same fault. Dashboard warning light was activated for this fault.

C1002 - Steering column motor torque position sensors
A problem is detected in the sensor(s) or the power steering motor assembly, as indicated by the code.
Check the system fuses and the connectors and wiring for opens, shorts and weak connections.
If the wiring is in good condition and the problem can be directly pointed to an internal component, it may be necessary to renew the entire servo motor assembly, since repairs are usually not possible.
The fault is present now. Take appropriate action to fix this sensor fault. Dashboard warning light was activated for this fault.


At my case the symptom still appears. Very rarely at the car start and leaving the steering in a particulary position the warning light does not appears.

If you have the opportunity and tools, you should try to calibrate it. With a OBD interface and the software above you can check for erros and livedata (steering angle).

Regards.

I got my hands on a OBD-reader and the error code C1002 came up, couldn't even calibrate the steering angel sensor
so new sensor.

I found this site www.powersteering-specialist.com which apparently also are this: www.stuurbekrachtigingspecialist.nl
and this: www.steeringanglesensor.com
and i tried to search thisforum for any treads with experience buying from them, but nothings showed up..
The sites seems at bit sketchy, really bad design. only reviews on their own site, not on trustpilot etc.


is there anyone who has ordered from them?

is the sensor not part of the steering colum unit?..Personally id replace the whole unit ...cheaper and imho cheaper.Plus if you go down the reconditioned unit you get a gaurentee..
I bought a second hand one for £40and it worked...just make sure you get a unit with the same numbers on it.
HTH

Definitely a bad sensor / adjustment, google for steering column sensor zeroing and you will find videos that show how they do. It's not really DIY since it requests some dedicated hardware ...

Thanks to Nick we know that it can be replaced / adjusted :-D

BRs, Bernie

I ended up replacing the steering column/motor as a complete unit..I used the short version of replacing it as discussed in the comments from the 'how to'..

Holy S%&T that was cheap! a colum i Denmark cost around £400!
The sensor is a part of the colum.

I tried to zeroing the sensor with my local mechanic equipment, without luck :/ so i will replace the sensor.

well i order the sensor with visa, so the bank can withdraw the if they are scammers

If you need a 'new' steering motor I'll source one and post if it helps?

Hi everyone,
I have this problem and get error code C1002. The dealer suggested I change the battery but that didn't help. I haven't had chance to try a calibration yet, can anyone confirm that this has worked for them?
Any other suggestions?
Thanks

It seems diy calibration is a bit hit and miss. You could pay a specialist or change the whole unit.
As said previously you need the numbers off the old unit. You HAVE to have matching numbers. its a plug and play unit.Just follow the how to..or the short version thats in the comments about it.

Hi nikrox,
I tried calibration (without MultiECUScan or AlfaOBD) and it didn't work. I'm a bit loath to buy one of these to try calibration with them if it doesn't work.
I'll try and take it all apart at the weekend to see if there's anything obvious like a loose wire and get the part details whilst I'm at it.
Cheers

Its your choice at the end of the day...when I removed my old one there was nothing I could see to fix..its basically a self contained electric motor.
The numbers you need are on a sticker,on the motor itself..they may be visible when its stillin place,after you removed the surround etc.
HTH.

I didn't get chance till now to try anything. I'm going to see if cleaning the contacts for the sensor plug makes any difference and if not buy a new one. I read this long thread about the sensor which is quite complicated but helpful: https://www.fiatforum.com/newbie-central/429433-newbie-power-steering-fix.html

And for replacing it I'll be using this one: https://www.fiatforum.com/grande-pu...-punto-power-steering-column-replacement.html

Cheers all

Well, I didn't remove the sensor but I took the various plugs out from the power steering harness (but not the one that goes into the sensor housing) and sprayed them with contact cleaner and it didn't solve anything. In fact it made it somewhat worse! The fault light will now come on again a few times after it disappears!

After the cleaning and during testing I paid a bit more attention to what AlfaOBD was telling me. It says for the fault C1002 the steering column motor torque position sensors are out of range. I watched the gauges readout for a bit, tracking the steering angle (I think) and torque difference. The latter did change as I turned the wheel but the former didn't change at all! I presume therefore that the error code is a bit misleading, the error isn't with the torque measurement but the angle measurement.


So I'm going to buy the sensor and try and fit it.
Cheers

TBH buying a second hand part,or a rebuilt unit is really the quickest way forward.
Once you have the replacement it can be changed in a few hours,and it really is plug and play.
If you cant get one locally Im happy to help by sourcing one and posting it etc.

Hi nikrox,
Thanks for the offer, I'll definitely considering it. I'm currently weighing up my options.

I'm in France, which either makes things easier or harder depending on your point of view! GPs seem more common here than in the UK, but my ability to find parts is hampered by the general reluctance to properly use the internet and advertise parts availability except for a few websites.

If I get only the sensor, do I need to do the calibration with AlfaOBD or MES? I thought I read somewhere that this wasn't necessary, but can't find where I read it.

If I buy a reconditioned steering column, then is the sensor already calibrated? Should I presume, but it pays to check these things!

Cheers

Hi "Billy le fou",

there is in Holland a company that rebuilds those steerings, I believe you'd buy one and get (some) cash-back when you ship them yours.
Otherwise, Oscaro in France does sell premium brand parts also...

BRs, Bernie

If someone here helped You fix -or better, understand- your issue, hit the thanks icon @ bottom right corner, it's free and makes us feel helpy ;-)

I have no ideas as to how to perform any calibrations.. I went straight for a second hand part off ebay.
