Supercharger Air Control Valve: Diagnostic Trouble Code Tests and Associated Procedures
ACV Circuit (for supercharger)

According to the signals received from the ECM, the ACV (Air Control Valve) maintains the pressure at the supercharger front and rear bearings
as close to atmospheric as possible. This prevents the bearing grease and oil leaking out due to pressure fluctuation inside the supercharger
housing.
