PS Light on Nissan Micra Initia

D

Domenica18

I'm hoping someone will be able to help me with my Nissan Micra or provide some advise. I've only had the car for the last year and a half, it's a 57 plate and passed through the Last MOT with near to no faults. On Thursday evening, after previously driving the car earlier in the day with no faults, when I turned the engine on I had the red PS Light come up on the dashboard. The steering is currently really stiffy and pretty undrivable, I don't want to cause any more damage. I've read pretty mixed things on the internet, I've had a mechanic look at the car and looking at a pretty expensive fix including a new Power Steering pump. I don't believe any electrical fault has been looked into, I've previously had issues with the boot locking and unlocking when driving (I'm unsure if these are connected). Any help would be highly appreciated!! Thank you! :)
 
Makes it difficult for me to look at it. Usually if your getting a PS fault then the fault is usually within the eps. Intermittent faults usually increase to hard failures. How intermittent is it?
 
So it's happened three times so far within the last two weeks. I had a quick look under the bonnet, (I'm no mechanic by any means) and couldn't see a reservoir incase the fluid had dropped. But then I'm reading its an electric system and can't find any information on whether they would be a fluid tank.

The car isn't worth much and if we're going to be quoted £700 to fix then the car simply isn't worth it. So any cheaper fixes would be a life saver.

Hi. I wonder if you can help me. I live in Birmingham.
I have a Nissan Micra which suddenly developed a fault: no power steering at all with the red warning light come on.
Have been told the P.S pump has gone faulty

I'm not sure of your year of car but. The power steering in micras is an electric motor on the steering column , and iv heard lots about fuses going. And people being told the mother has failed !!!! Or had it canceled on the computer. Check with guys who have your year and had this problem. Don't think any of them had a pump as far as I know. But check

V just done some checking and it would appear that yours is fluid hydraulic as most cars are , so yes your pump may be up the wall. Unusual I admit. They usually leak. Scream , seiz , or otherwise shout at you they are poorly , to just Not pump is odd. Check with a friendly mechanic. Who can confirm it.

Hi I wonder you you be prepared to come out to Northampton regarding Ps on a 54 plate mirca

Not too prepared…. I’m not a mechanic, I have a demanding job and a more demanding wife. I do this to help people, if I was passing on other business I would pop in but I have nothing planned this side of Christmas to travel down there. What’s up with it, but I have also just replied to your pm.
 
Thanks for reply please bear with me as I am not very good at this sort of thing basically just after someone who can sort out the power steering on a nissan micra that reads no faults on the ecu meter.
 
If it’s reading no DTC that’s unusual? As pm’ed to you;

Usually the unit is very self contained and usually when the ps light is on, it's a failure with the unit. Little fiddly to replace but not hard. Depends how attached you are with the car, as the units are getting more difficult to find and price is going up. Is the car worth that much!!

What type of person do I need to look at my nissans Ps problem mechanic or auto electrician

Mechanic to remove and replace as a auto-electrician won’t be able to do anything apart from clear DTCs. They might tell you they can…. But they won’t be able to as the units are very self contained.
 
Thank you very much for taking time to explain. I now know what I am dealing with no magic fixes, Just mechanical minded person need and a bank loan ha ha. Thanks again better than being in limbo best regards Craig
 
good morning micra world
first time posting here
i have replaced the eps motor and column due to the dreaded ps light the unit was a virginized refurb unit which after fitment and code erase worked well until after about 5 mins when the immo light comes on but engine still runs

any advise on fixing would be greatly welcome
 
sounds like the refurb company has ripped you off! They do not have the technology to re-virgin a unit! It was never released to the public. All they done is possible changed the nvm and made it possible dangerous
 
Hello Everyone,
My Nissan Micra is showing a PS warning light . It is 2005 model petrol car and this issue came up suddenly while I was driving. What could be the reason?

Mine first showed the fault at ignition on, not when I was driving. It is a 2005 model and I think this is the first model year to have the EPS as opposed to the hydraulic system. The power steering was not functioning and the car was difficult to drive. I installed the Carista app onto my phone and used this and my OBDLink bluetooth device to delete the fault code. The Carista app is free for 30 days so I cancelled my subscription when they sent me a reminder email a few days before they were about to charge my paypal account. It has been working for a few months now. If you have EPS, I would be really interested to know whether your EPS actually failed (ie steering became stiff) while you were driving. Or did the light just come on while driving but the system remained working? Or has anyone else reading this had their EPS fail while they were driving? It is obviously a highly dangerous situation if these systems are regularly failing while driving (as opposed to ignition on, like mine). The loss of power will unexpectedly snatch the steering wheel back if you happen to be negotiating a bend at the time. I have heard of a fatal accident where this happened (on a different vehicle).
 
08 plate. My PS light went on and then car broke down after refilling at petrol station. Got it towed back home & told it is something to do with the fuel pump. Finding out later this week when I can find a garage to tow it to them the cost to fix. I have spent more money on repairing the car since I got it in 2021 than it cost to buy it. Anyone else had similar issues with regular things going wrong with their Micra?
 
Well you have come to the right place if you want that info. It is there if you put in the effort to trawl this site. From my memory of doing that a while back (and from my own experience) the problem areas seem to be PS, security system, radio / cd player and electric boot lock. We inherited our 2005 model from my wife's brother who teased her mercilessly until the day he died. So when the radio comes on or changes channel by itself, or the boot unlocks itself she thinks it is him still teasing her. I have tried to tell her that it is happening to other people as well but she isn't convinced yet and still shouts at him whenever something strange happens! I have a feeling that the electrical problems may all be related to a common electric boot lock wiring fault that may interfere with other electronic systems on the vehicle like the PS and the radio. That's only a vague suspicion though, based on the fact that these three issues seem to happen concurrently and also based on the knowledge that the vehicle does use a common CAN bus to communicate between devices. I certainly wouldn't bet money on that being the cause though. As for spending more money on the car than you paid for it, that is always the issue when buying an older vehicle. Its a gamble that often doesn't pay off. I am an ex automotive engineer and I quite enjoy tracing and repairing faults on vehicles. If I wasn't (and depended on garages to fix things) I think I would research a reliable car model and buy a newer vehicle than 2008.
 
My Ps light has come on and gone off and now on again. 2004 S

I am convinced it’s a fuse as the boot has always not worked, lights can be intermittent and battery etc.

It’s now on permanently with heavy steering and I want to get rid of the car but would like to resolve the power steering issue if possible so I can sell it and not scrap it.
 
It sounds like you do have EPS fitted however I thought that EPS was fitted from 2005 MY onwards. But I could be wrong and it is also possible to have a 2005 MY vehicle registered in 2004. If you do have EPS fitted then see my previous post about using an OBDLink device and the free Carista app. Mine is still working perfectly about a year after clearing the fault. From reading what others have said on this forum, if you can't clear the fault on the EPS with a code reader, there isn't really any other safe option apart from paying a dealer a fortune to fit a brand new unit. If instead you have hydraulic PS then I think checking the PS fuse is a good place to start (assuming it has one) and I guess it will be easier to replace or repair than the troublesome EPS. If it exists, the PS fuse will have its own dedicated fuse and shouldn't share any power lines with anything else for safety reasons.

Update: the Ps light came on as battery was low, once fully charge it turns off and steering goes back to normal
 
Thanks for updating. That is useful info for others reading this thread. That sounds like a plausible reason for the light coming on temporarily. Mine had a few episodes of PS light staying on at ignition on and heavy steering before the light came on permanently with EPS disabled. Mine could have been a combination of a low battery and a "three temporary faults within so many startups makes a permanent fault with EPS disabled" policy. I don't know whether the EPS does work that way but a policy like that is quite common particularly with safety critical systems like EPS. That has also made me think of another possible way that a fault in the wiring harness to the bootlock could result in the EPS light coming on. Harness shorts are very often not dead shorts. So they are capable of drawing sufficient current to drain the battery over time but not sufficient to blow the bootlock fuse.
