Code P02EA GMC Description

The Intake Air (IA) Valve is a normally open valve and is only operated during a DPF regeneration. The position of the IA valve is controlled by the Engine Control Module (ECM). The IA valve system uses a position sensor located within the valve assembly to monitor the position of the valve. The ECM sets the OBDII code when then Diesel Intake Air Flow Position Sensor is out of factory specifications.
