Hi there. The P0033 OBD-II error code is a generic code that typically indicates a problem with the Turbocharger or Supercharger Bypass Valve Control Circuit.

In most cases, the reason the code is triggered is due to a vacuum leak within the turbo, which can cause the engine to shut down while driving. There are other components that could also be the source of your problems on the Pontiac, which is why it might be a good idea to have one of YourMechanic’s certified mechanics come to your location to complete an inspection to determine why the car is not starting.
