Perform the torque sensor zero point calibration:

Locate the reservoir on the body of the power steering pump. There will be two metal tabs that hold the reservoir to the pump body. Pry these with a flat screwdriver and pull the power steering reservoir from the pump body. You will notice a metal nipple coming from the pump.

Locate the two metal snap flanges on each side of the reservoir. Use a slot screwdriver to pry them apart and pull the reservoir out of the pump body. The reservoir will have a large tube nipple that slips out of the pump body. Be sure to keep the O-ring inside the pump.

1. Set the steering wheel to the center point and align the front wheels straight ahead.
2. Turn the ignition switch off.
3. Connect the Techstream to the DLC3.
4. Start the engine.
5. Turn the Techstream on.
6. Calibrate the power steering ECU.

When that happens, your car’s steering system will revert to manual operation (i.e., your muscles do all the work). As a result, the steering wheel will become very difficult to turn. Electric power steering can stop working suddenly and render the vehicle very difficult to drive as well.

Can you drive without power steering? Yes, you can drive without power steering, however, that does not mean you should! You may notice your steering still works, but soon you’ll regret not going to the gym regularly because the steering wheel will be very hard to turn.

Driving your car for extended periods without power steering fluid can damage the pump. While there’s nothing that physically stops you from driving your car if you have a power steering fluid leak, once the level drops, your pump runs dry. This causes increased friction and heat and can quickly cause expensive damage.

You might also want to check the underside of your spare tire cover. There should be a Service Parts Identification label. Check the label for the code NV7. If it’s there, then your car has variable power steering.

At its most basic level, the steering system’s power steering pump can generate up to 2,000 psi of hydraulic pressure. This hydraulic pressure is metered to a steering assist cylinder through a steering gear pressure control valve.

Variable assist power steering systems are used on a variety of vehicles to provide maximum assist while parking and less assist and a firmer feel at highway speeds. It is typically accomplished by controlling and varying the pressure to the steering gear or rack. …

These vehicles may experience a temporary loss of electric power steering (EPS) assist followed by a sudden return of EPS assist, particularly during low-speed turning maneuvers. If EPS assist is lost and suddenly returned, the driver could lose temporary control of the steering wheel, increasing the risk of a crash.

A vehicular safety system designed to keep drivers from drifting out of their lane as well as off the road. Known as “steering assist” the lane departure system may also tug on the steering wheel to actually nudge the car back in lane.

While car recalls don’t have an expiration date, they are only enforced for “reasonable periods,” the agency says. Basically, a recall is over if a vehicle’s manufacturer goes out of business, or if the parts needed to make the necessary repair are no longer being made.

Electric power steering (EPS) is a key technology for highly automated driving. The EPS has an electric motor which controls the vehicle steering. With an electric motor the EPS controls and assists vehicle steering and provides an optimal and enjoying steering feel.
