In Jatco/Nissan JF010E (RE0F09A/RE0F09B) units, the pump body flow control valve bore wears due to constant valve movement. Wear allows critical pump pressure to leak into the low pressure side of the pump, reducing pressure needed for proper engagements and push belt pulleys to operate correctly. Sonnax oversized pump flow control valve 113741-26 allows the pump body to be refurbished and hydraulic control to be restored.
This Sonnax valve is designed to work in the OE version with the longer valve and shorter sleeve. It should not be used in the OE version with a short valve and long sleeve or code P07468 or P0868 can result due to excess bypass flow. Related Sonnax valve 113741-07 should be used to replace a worn OE short valve and long sleeve design.
Vacuum testing at the port(s) indicated fails to hold the recommended minimum in-Hg, or if wear is visually detected.
