What is the Power Steering Control Valve all about?

Power steering pumps create high pressure in order to push fluid through the system, into the power steering rack, and provide good handling. There are many different components that play critical roles in this process, and the power steering control valve is one of them. You might be more familiar with this as the flow-control valve.

In most setups, the power steering control valve is located at the outlet of the pump, where the fluid leaves the pump and enters the supply line. It regulates the pressure of the fluid in the line to the correct PSI. If the valve fails, the fluid pressure may become too low or too high. Excessive pressure can cause damage to the supply line, creating leaks and fire hazards (power steering fluid is flammable).

Keep in mind:

  • The power steering control valve is not part of any service or maintenance regimen.
  • It is not possible to check the valve for operation during basic maintenance, so it will only be inspected if there is a problem.
  • Failure of the control valve will create problems with steering and handling.
  • In most instances, valve failure will require replacement of the power steering pump itself.

How it's done:

  • The power steering control valve is checked for replacement
  • The power steering control valve is removed
  • The new power steering control valve is installed
  • The power steering system is refilled and checked for leaks
  • The engine is run and the power steering system operation is checked

Our recommendation:

While the power steering valve does not require any regular maintenance you may request that it is diagnosed if your car exhibits any of the symptoms. Your power steering system is an important component of your vehicle, ensuring simplified handling through all types of turns. However, a failing power steering control valve can cause drops in fluid pressure, creating harder steering. Have any malfunction or problem with your power steering system inspected by one of our expert mechanics immediately.

What common symptoms indicate you may need to replace the Power Steering Control Valve?

  • Hard steering at higher speeds
  • Whining noise during turning

How important is this service?

Your power steering system might not be as critical to vehicle operation as the engine and transmission, but it enhances safety and makes steering easier. If you notice any problems with your power steering system, have the vehicle inspected and the problem diagnosed as soon as possible.

Top-notch! Timely, competent, and thorough with the 50-point inspection. I got much more out of the 50-point inspection than the initial service request---definitely above and beyond!
