charge air cooler p026a issues

[Sonoita2]

2012 ram 3500 diesel check engine light came on
Code read was P026A and P2000

O2 sensors and harnesses were replaced 1500 miles back.

Sounds like a Charge Air cooler issue to turbo.

Any form feedback is appreciated.

Ps main radiator was replaced 3000 miles back, it was packed with grass, bugs, etc

Thanks Sonoita2
