CEL on - 3 codes - could they all be the cat?
Greetings! I am hoping someone might have some good news for me
I got a great deal on my used accord last year, but the CEL is on and it's time to get a sticker. She has 186k miles, runs great (a little noisy) and gets 24-26mpg.
Went to Autozone for the codes so I can get to work on fixing them
P0171, P0420 and P1457
Seems obvious I'll have to replace the cat, but am hoping to avoid things like the O2 sensor, fuel injector, EVAP canister vent-shut valve
Any chance it's all just the cat and I'll get off easy here?

P0420 only means the catalyst is working below threshold efficiency.
This does not mean the catalyst is dead, if the A/F mixture is incorrect the catalyst cannot properly work. It does not mean the catalyst is faulty.
Fix the EVAP issue, it may be causing the lean running issue, which would cause the catalyst issue.
