Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your question.
If you are getting a PS light and have no power steering, that is a indication that you have a EPS type power steering system. EPS means Electronic Power Steering. The Power Steering system has a control unit which will need to be scanned to determine the fault. Failure to address this issue could result in a more expensive repair. So you are going to want to address this ASAP. It also of course is a safety issue. I understand that you can't afford a expensive repair. But there is no way of knowing how expensive of a repair this could be with out scanning the system to see what code you have.
It could simply be due to a low battery voltage surge. The only thing I can suggest you try before getting it scanned is to disconnect the negative battery cable for 15 mins to do a hard reset on the car. Then start it and see if power steering operation returns to normal. If it doesn't, then it will need to be checked to determine the fault in the system.
Do you have any more questions on this?
Auto Zone will not have the tools to check this system. This is going to need to be looked at by a repair shop or a dealer.
I do not recommend driving the car long distance if the hard reset does not work. I would recommend you have it checked before doing further damage to the system if driven.
