What causes overboost?
Overboost is when the turbocharger runs at a higher pressure (forces more air into the engine) than would be sustainable on a constant basis. Drivers do not control overboost manually, it happens automatically when the car is in a certain gear at certain revs and the throttle is fully open.
How do you fix a P0234 code?

Can I drive with error code P0299?
The presence of the P0299 code can point to some rather serious mechanical failures, especially if left unaddressed. If any mechanical noise or drivability concerns are present, then the vehicle should be repaired as soon as possible.
When is the p0234 diagnostic trouble code detected?
When is the P0234 code detected? This diagnostic trouble code (DTC) P0234 will set if the boost pressure sensor signal is above the predicted range. The boost pressure sensor responds to pressure changes in the intake manifold. This pressure is created by the turbocharger and changes with accelerator pedal position (APP) and engine speed.
What are the symptoms of a p0234 turbocharger overboost condition?
By regulating the pressure to the wastegate actuator, varying degrees of boost are possible. The symptoms displayed for a P0234 code will depend on the cause of the overboost condition: The service engine soon or check engine light will illuminate. You will experience a loss of power. The engine may show signs of overheating.
How much does it cost to repair a car p0234?
