What does speed-sensitive steering mean?
Speed sense steering system does exactly what its name implies. It senses your car’s speed and adjusts the amount of compensation or assistance that it provides to give you the feeling of being in control while steering 100% of the time. At low speeds, the system will provide the most assistance.
What causes sensitive steering?
Excessive Response/Touchy Steering: This is generally caused by excessive pump pressure. Pump Noise or Groan: This is most commonly caused by a restriction or air trapped in the system. It can also be caused by heat buildup. (This would include a loss of assist.)
How do I know if my Mercedes has speed-sensitive steering?
RE: Speed-Sensitive Steering just take a peek on the steering box lugnut. if there is a wire attached to it, then you have it. this is a black wire and the it goes up to the connector on the wheel housing on left side (lower area).
How is a steering system checked for looseness?
To check the steering box, you need to raise the front of the car but keep its weight on the wheels, and then get underneath it while someone else turns the wheels slightly. To do this safely, you can drive onto a set of ramps, but they must be resting on a level surface, directly under the wheels.
How do I fix a sensitive steering wheel?
The only way you can affect the feel a car’s steering is by adjusting the air pressure of the front tires—and that will change the feel of the steering only to a minor degree.
Can a power steering system self diagnose a problem?
Keep reading to find out how you diagnose EPS issues. Most electric power steering systems are able to self-diagnose any faults, with the use of diagnostic trouble codes (DTC).
What makes a power steering system more sensitive?
The control valve responds directly to input from the pitman arm or steering shaft. The actuation of the control valve is based on input geared to slower vehicle speeds where assist is needed the most. This configuration makes the steering more sensitive at higher speeds.
How can I tell if my steering wheel is working?
This condition can be detected when the vehicle is moving, as the steering wheel is sensitive to small inputs. The controller is then in parking mode with the pump delivering full steering assist. An intermittent interruption of the HWSS with the vehicle moving will produce minimum power assist.
What happens when a power steering controller fails?
When a sensor or input fails, it will most likely produce an intermittent failure. An intermittent interruption to the vehicle speed input to the controller will produce an increase in power assist. This condition can be detected when the vehicle is moving, as the steering wheel is sensitive to small inputs.
