    Default Power steering electronic variable orifice

    Does anyone have any idea on how to test if the electronic variable orifice is what's wrong with a power steering pump? It's very difficult to steer at idle in the parking lot but gets a little easier when the engine is revved a bit. The hydro boost brakes work fine. Not sure if I should just replace the pump.

    After a bit of googleing I found out that the problem may be the EVO sensor on the steering shaft. I'll unplug it to find out if that is the problem and post back later.

    After disconnecting the valve on the power steering pump it is still hard to steer. Does anyone know how to check the valve or if the pump is worn?
