The OE flow control valve is designed to increase pump efficiency by rerouting excess line pressure back to the suction side of the pump. It is common for the plunger valve to become stuck open, or for the canister to wear. This decreases line pressures and results in delayed engagements. Sonnax pump flow control valve kit 56200-03K eliminates the sticking and wear problems with redesigned and precision-machined parts.
