1997 Camry V6 has codes P0401 and P0402 so what should I replace?
What is your question?
My 1997 Camry V6 has codes P0401 and P0402. The VSV for EGR valve passes the 9V battery test. It is part 90910-12174. There are 2 similar looking parts in the same vicinity that I'm wondering about. They are VSV for EVAP and VSV for ACIS. Would either cause those codes?
I hope that the problem isn't in the VSV built into the charcoal canister because in 1997 it's reportedly not a separate part.
What makes this problem better or worse?
car always runs fine

After TESTING - you can decide what needs to be done.
GOOD LUCK!
Great info from Pushrod; just additionally - your codes, as they stand right now, are not related to evaporative emissions, and as such should not be related to the canister. At least according to the data shared. I'd lean towards a possible EGR passage restriction due to 23 years of carbon build up. But that's my armchair perspective; hands on testing Is needed.
