EVO sensor. Also known as steering speed sensor. Bad power steering pump, hose broke.
The wire in the steering column has to much strain on it and it snaped. Easy fix if you extra wire laying around. Just rip the steering column apart
Steering fluid leak.
My 92 Silverado right front brake sticking why
the most likely cause of that would be the power steering pump failing.
It's primary purpose is to control excessive feedback into the steering wheel. For example, when you hit a large pothole, some vehicles would feed back that energy into the steering shaft causing the steering wheel to jump left or right suddenly which could cause the driver to loose control of the vehicle. Not all vehicles need one of these.
You may want to check this with your dealer, but not too recently the cav and sunfire had a recall on the power steering. Something about a bad gear and power failure when making left hand turns. They would either replace the faulty gear or the whole rack and pinion assembly. Either way have it checked out. A steering problem is not a nice problem. It may cause accidents or death.
