P0299 2016 Chevrolet Silverado Code - Engine Underboost
Quick Answer
The Engine Control Module (ECM) uses the Manifold Absolute Pressure (MAP) sensor input and turbocharger actuator output to control the amount of engine induction system boost pressure. Common causes include Faulty Turbocharger Vane Position Actuator, Air leaks between the turbocharger and the intake air flow valve, Airflow restrictions in air ducts or air filter. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
