1. Content There is a possibility that Fuel flow produces cavitation erosion on the surface of Suction Control Valve (SCV) needle. Negative pressure peels plating film on the surface of SCV needle. The peeled plating film interferes with the movement of the high pressure fuel supply pump. It causes engine stall, rough idle or smoke exhaustion. In this case, you can replace only SCV to solve it. Therefore, we revise “Diagnostic Procedure without Diagnostic Trouble Code (DTC)” for diesel engine in Service Manual and set up SCV as service part.
2. Part number and name of SCV 16626AA000 VALVE AY-FUEL CONT
3. VIN Break We improved durability of SCV against cavitation from start of production for 09MY Forester, 09MY Impreza and 10MY Legacy. VIN Break is as follows.
