P0599 chevy sonic. Seemed like this P0599 manufacturer are a lot of things. Im so confused already. First, it says thermostat control circuit high. Then cruise control sensor, then 4x4, now the airbag light's on. we don't know anymore. Dealer asks$3000k for fixing 2 problem only. And I checked the sensors they're all @$29-$39.99 range.

The first P0299 you get does not cause a check engine light, it goes into limp mode which allows only 3 psi of boost. On the next ignition cycle the car is back to normal power, If you get another P0299 on that cycle it turns on the check engine light. If you don't it clears the code and it goes back to step one.
