Description of DTC code P0299

Diagnostic code P0299 OBD2 indicates stopping that the turbocharger pressure is not within the expected range. This is detected by the PCM (Power Train Control Module).

In the normal operation of a supercharged vehicle, the air entering the engine is pressurized and this contributes to the power of the engine. When this DTC code is established, a low power performance can be noted.

The turbochargers are driven from the exhaust to use a turbine that works as a reinforcement of the air intake. It is located above the intake side of the engine and is generally driven by a belt and proceeds to reinforce more intake air, this, without having any connection with the escape.
