Power Steering Problem 2015 Versa S
I purchased a second Versa for my daughter a month or so ago. It is a 2015 S manual shift with about 77K miles.
I have put close to a thousand miles on it to test it and make sure it is reliable before giving it to my daughter and it had been flawless.
However, just this weekend the power steering assist quit. The PS light on the dash came on. The car still is operable but just with very heavy steering.
After turning off the car and restarting a bit later it worked again. The same thing happened again a little later in the day.
We were doing a lot of slow speed stop and go driving as she was getting lessons on driving a stick. The temperature was quite warm that day, about 85F.
The fuse was checked and is fine.

The last couple of days it was driven some more without incident.

So I have a couple of questions.

Can I pull the codes if there are codes for PS dash light issues with the torque app on my phone? If not what do I need to get the codes without going to the Nissan dealer?

I don't think it is the electric motor as it would probably not be intermittent. I think it must be a sensor malfunction.
I do not have a good understanding of the power steering system yet and was hoping someone here could help with that. For instance, How many sensors, located where and what their function is?
And are they replaceable without a major component replacement?

I did install a rostra cruise control on the vehicle a couple of weeks before the steering issue.
The cruise works fine and the car was driven quite a few times with no issues until just this last weekend.
I don't think it is related but there is the potential, as I was working under the dash.

Maybe you tugged on a wire leaving it just barely making contact.

Question about cruise control installation: Did you remove the large plastic lower dash below the steering wheel or not? I'm going to install one this week and am looking for tips.

PM me about the cruise control and I will help you. I have done the rostra install twice now on Versa S models. I don't want to get a side discussion in this thread.

Q Meyers,

You have your PM's turned off and I can't reply to you. Turn them on or you can PM me your phone and I will call you.

Thanks, PM now on. I also started a thread in the interior section.

'We were doing a lot of slow speed stop and go driving...'

The motor there is not intended for maximum use a lot. The service manual states that using the PS exactly like you state there if 'extensively and at low speed' will overheat the motor and the control device then cuts way back on the assist power until the motor can cool off.

Likely what happened there. In normal use it never happens.

Thanks amc49

Do you think the codes would confirm the overheating of the electric motor? And do you know if the Torque app will display these codes?
My daughter will be taking a trip in the car next month and obviously I don't want any issues.

Any codes there are chassis ones and around 1600, or C16XX series. The codes only show with a solid malfunction, they do not with the considered possible 'with a normal system' overheat I mention there. Meaning the PS light comes on only and no codes are present. The android app needs to be able to pick up chassis or 'C' codes, I do not know if it does or not.

The torque app showed no codes, current, historical or otherwise. The car has been driven most everyday since without any more issues. Still I am a bit nervous about it.
