Check the 'Possible Causes' listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.
The cost to diagnose the P0299 Chevrolet code is 1.0 hour of labor. The diagnosis time and labor rates at auto repair shops vary depending on the location, make and model of the vehicle, and even the engine type. Most auto repair shops charge between $75 and $150 per hour.
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. The ECM calculates a desired boost pressure value and monitors the actual boost pressure. If the difference between the actual boost pressure and the desired boost pressure is less than or greater than a calibrated threshold level, the ECM detects that the amount of detected boost pressure is out of range. The Diagnostic Trouble Code (DTC) will be set when the ECM detects the difference between the actual boost pressure and the desired boost pressure in the intake manifold is less than the expected range for 12.5 s. The 12.5 s time is not continuous but cumulative. The timer may sum up a heavy load condition obtained during different maneuvers.
