Code P0299 Acura Description
The P0299 diagnostic trouble code (DTC) for Acura vehicles indicates a turbocharger underboost problem.

Turbochargers are used to increase the efficiency and power output of an engine by compressing air and forcing it into the combustion chamber. When the turbocharger is not providing enough boost pressure, it can result in reduced engine performance, decreased fuel efficiency, and potential long-term damage to the engine.
