Hi,
The code is related to the positioning of the pintle valve in the EGR. Have you checked to make sure the pintle is closing fully?
I attached the diagnostics below. Take a look through them and let me know if you are comfortable performing them.
Let me know if this helps or if you have questions.
Take care,
Joe
