Technical HELP my Power Steering Light is ON! - Start here!

Yeah my power steering come on, on my car only just bought it last week and took it back to the deeper so he could run it through the diagnostics and it went off after that but I don't know if the dealer has just found the problem and just did a dodgy fix on it yet to find out haha
 
Just tried to change my stereo but i put my original one back in due to problems with the replacement and now my steering light it perm on and it feels really light.. help
 
I have read above, my car steering light come on different way what the above didn't mentioned.
When I have turn steering only to the right from 3/4 to full lock on slop uphill the light come on and steering cut power become heavy. Plug multiscan find no error code?
Then I switch the engine on again after 5 minutes no light and steering back normal and it do again when lock right on slop uphill but not on flat floor weird?
very frustrate :bang:
I was expect to find error code to flow fault but why no code?
 
Seems this thread is still going so will try here first.


Came out of work about an hour ago, just got out of car park and noticed PAS light was on - BUT- the steering wasn't heavy.


Drove home, a little cautiously, with no issues, PAS remained on, but it is working - there is no heavy steering!


Obviously it hasn't been on a code reader yet, or a multi meter - just in case alternator is n way out - but would have thought if it was the latter I would have had other issues.


Appreciate it will be a stab in the dark at the moment, but any other pointers to what could be the issue (assuming there is one!!)

Best thing to always start with is a fresh battery. Even a slight drop in voltage will sometimes bring on the light.
Get yours tested at a local motor factors or halfords and purchase a new one from eurocarparts.com
 
Hi All

My Sons 2005 1.2 has just started displaying the red light and hsi steering is feeling abit heavier, albeit intermittently.

I'lll clean teh battery terminals and check the battery tonight. If it isnt that I gather it needs a new PAS motor? I've seen these on ebay for £80 exchange.

Is this a DIY job? Or do I need special tools?

Many thanks

no special tools needed apart from torx screwdriver and soldering gun if you are changing relays

Thanks for the reply. I have torx drivers. I was thinking of fitting one thw exchange units so no soldering from me. Typically the light has gone off and not come back on since. He just had a new wiper assembly fitted by a garage and I wonder if they disconnected the battery to do this? Oh well tuime will tell I suppose.
 
Hi

Just Logged on here. So. The P-S light (54reg Punto) comes on periodically. Restarting the car re boots the P_S. It would appear from reading the posts that there are several possibilities starting with low Alternator output and Or a poor Battery. through Bad Earthing, connectors etc; Once these are ruled out it becomes more Expensive!.

In order to diagnose I have an ELM 372 (V1.5a) interface to USB and can read a limited (engine only) codes. One I get is U6102 which would appear to be a Wiring code?.

Also can the ELM 327 be used with Multi-scan software for more fiat codes?.

That could be useful?

A further issue, if anyone has experienced it, is a tendency to act as if "misfiring" when under load (in gear) at about 1700rmp?

Pete

Ref above earlier post;- Misfire traced to Dodgy Plug Leads, replaced plugs as well now good.

After a period of several weeks without, the Steering light is back on? PAS works perfectly on both standard and city settings? . NEW battery fitted. Idle Output from Alternator 14.0V. rises under acceleration. In my View this should be "good"?.

Any Idea`s?

either pas motor, pas ecu or steering column sensor, best is to plug it to a computer to see what error it logged

sold pas motor to some guy whos mechanic tester showed pas motor error code- he called me next day that pas still doesnt work, i said cant be cuz i tested it before sending it out, but still , i send him another one which didnt work for him too
then i send him pas ecu cuz there is no way 2 pas motors got damaged during shipping, replaced ecu and pas started to work, later found out that his pas motor and the ones i sent him were all working normally
all this cuz his mechanic had old tester
 
I had my PAS light come on my MK2 punto and got a 2nd hand ecu and power steering pump from scrap yard, easy to fit. But I found to my cost that it isn't always the pump and ecu that fails. It can also be the torque sensor that fails. I found it cheaper in the long run to replace the whole steering column. I'm not mechanically minded but did it myself. Got the same coded steering column from scrap yard(looked for one with a decent steering wheel as this suggested low usage) then was told I would need to swap ignition barrel over(2 gold coloured security screws which I used a hacksaw to cut a groove in so I could use flat head screwdriver on) then changed my wheel over(simple job) and then bolted it all back in car. 2hrs of my time and £60 for steering column and touch wood its been fine. If I remember there is a tutorial regarding the above procedure but I did have a mechanic on hand if I couldn't do it. I hope this help anyone who has the same issue. (please don't be put off of doing this job yourself) :)
 
About sixteen months ago I 'cured' an intermittent p/s fault by removing the motor and cleaning the power connections at the plug.
It came back a few weeks ago. The warning light would clear with the key at Pos II but come back again cranking the motor without touching the steering wheel.
The three year old battery is at 12.6 Volt cold and 14.2 Volt at idle with lights, fan and electric demister on.
Removing the 60A maxi fuse ( the big blue one ) in the engine fusebox and replacing it after starting allows the p/s to work.
The p/s return wire piggybacks on the battery negative terminal. Opening it the mating surfaces of the terminals were dirty. A clean with a file and now it works fine again :)
 
Sorry to hijack but it's all related my red steering light has been coming on.
the battery needed charging last week as the car wouldn't start so I hooked up my optimate (didn't need to disconnect the battery) and left on the trickle charge all week - NO LIGHT Before this stage. Took for a 20min drive no lights on the dash but I got to the last turning back to my house and boom the red light appears but nothing seems wrong with the car. The light when out if I turn my car off for approx 15/20mins. Same happened yesterday too after about 1min of driving on the way to work and after 5mins on the way home!

Here's the odd thing it didn't do it this morning.

Maybe I'm clutching straws but I know drops in voltage can set it off. I was wondering can it also be set off by an upper limit in voltage (not sure if that's even possible)?
 
After nearly a year after new battery and extra earth straps and cleaning leads session, my dreaded red steering light turned up Monday and steering heavy.
I charged the battery up all Monday night and all day yesterday. Refitted battery- still red light and heavy steering.
I am going to order a reconditioned one and get my local garage to put it on. They will have the tester to match the unit with steering sensor. I can't now do things like this anymore- age has caught up with me , lol.
When sorted, I will put another larger battery on the car- throwing away the silly battery box and making up a cradle to hold the larger battery tight.

When Fiat know the amount of amperage that it takes to use the electric steering, they then put the doziest titchy battery they could find on the cars- coupled with a small output alternator. There was nothing wrong with the hydraulic system- worked on vehicles for 70+ years.
