Im getting code P02E7 and the DPF will not regenerate, Yes

Customer Question

Hello Im getting code P02E7 and the DPF will not regenerate
JA: Just to clarify, what's the exact code? And have you tried to reset it?
Customer: Yes it is intake air valve flow position performance and Ihave reset the code and retried. I have also had the DPF cleaned and replaced the MAF
JA: What is the model/year of your GMC?
Customer: 2007 C5500
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: Cleaned the DPF and all intake hoses and replaced the MAF
JA: Anything else you think the mechanic should know?
Customer: When the code is cleared and I restart the bus the yellow DPF filter light comes on then a few seconds later it changes to red. I hit the regenerate button and it begins to regenerate for about 2 minutes before it is shut off by the computer and the P02E7 code pops up and it will not go back into regenerate mode
