P0033 Turbocharger/Supercharger Bypass Valve "A" Control Circuit

Car was off the road on a trickle charger for 5 months and every year I get codes when I put it back on the road. Disconnect the battery and all is well but this year the P0033 code is sticking around.
The car runs & drives fine and looks like its the "Supercharger Bypass valve adjustment" Any help with fixing this code is appreciated. Thanks !

I had to replace the Bypass Regulator Solenoid, code is gone all is well.

Since disconnecting the battery didn't resolve the P0033 code this time, it's likely a more persistent issue with the turbocharger or supercharger bypass valve control circuit.

I recommend checking the wiring and connections associated with the bypass valve to ensure everything is intact and functioning properly. If the issue persists, it may require professional diagnosis and potentially replacing the bypass valve or addressing any underlying electrical issues.

Read this guide about turbocharger issues, there you'll find plenty of possible causes and how to fix them.
