My info could be wrong. EGR valves are not exactly small and are pretty well identifiable.

Is this a VVT engine, is there a chance EGR is done with valve timing and not a separate valve?

I went to double check being the confusion -
I see EGR for 06 but not for 07.
confirm codes - if same codes - try another scanner advise.

With VVT it's likely not got a valve. No need as the strategy for VVT can do the same.
