What is a Evo sensor?
EVO means Electronic Variable Orifice. The EVO valve is a key component in variable assist systems. A properly functioning system requires proper operation of the EVO valve (see below), control module and vehicle speed sensor.
What is power steering Evo sensor?
The vehicle computer monitors vehicle speed and steering wheel action to activate and deactivate the solenoid located on the steering pump, controlling fluid flow to the steering gear. At slow speeds, the EVO solenoid is fully open making steering assist easier.
What is EVO solenoid?
The “Electronic Variable Orifice” (EVO) steering system was introduced by General Motors. The vehicle’s computer monitored vehicle speed and steering wheel action to activate and deactivate a solenoid on the steering pump that controlled fluid flow to the steering gear.

How does variable assist power steering work?
The variable-assist power steering works flawlessly by regulating the pressure of the steering gear. With this technology, the sensor tracks the speed and rotation of the car’s wheel and indicates the control unit. The unit regulates the pressure that reduces the flow of fluid into the steering gear system.
What is variable orifice?
1. n. [Production] A small variable profile valve put in a flowline and used with a pilot to restrict the flow into the pilot and make the pilot more or less sensitive to changing conditions.
What is variable assist power steering?
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.
