P0234: Turbocharger overboost condition
Boost pressure exceeded the ECU's permitted target for the operating condition.
P0299: Turbocharger underboost condition
The engine did not produce the boost pressure requested by the controller.
P0420: Catalyst efficiency below threshold, bank 1
Upstream and downstream oxygen-sensor behavior suggests insufficient catalyst oxygen-storage performance.
P2002: Diesel particulate filter efficiency below threshold
The ECU calculates that particulate-filter performance is below its required threshold.
P2015: Intake-manifold runner position range / performance
The intake-runner position signal is outside the range expected by the controller.
P20EE: SCR NOx catalyst efficiency below threshold
The SCR system is not reducing NOx emissions as effectively as the ECU expects.
