Apart from being a 30 year old gas guzzler with 500,000 miles on it :>D

There are three situations where emissions requirements may temporarily be extended or waived:

1. Emissions Extension - for vehicles that are temporarily located out-of-state
2. Hardship Waiver - for vehicles that have recently failed an emissions test and the owner is unable to obtain necessary repairs due to a financial hardship
3. Repair Waiver - for vehicles that have failed an emissions test after undergoing emissions-related repairs.

What are the codes coming up?

fix the reported code fault sensors then reset the ECM using a scan tool
turning off lights does not fix problems

change your oil and oil filter. Add a bottle of octane boost to the fuel tank then top off with fuel. Drive vehicle for about twenty minutes then have emissions tested. Unless you have a bad catalytic converter, you should pass emissions.

code 0449 evaporative emission control system vent valve solenoid circuit malfunction check your fuses as well as connections and power going to the solenoid see manual for location of valve

P0455 stands for evap emissions detection leak and p0449 stands for evap emissions vent control circuit. You should go to a parts store and see if your able to purchase and install. Best of luck!

catalytic converter is the way to fix your problem because they do an emissions test and the code want go away even if you get the light off before you take it in they will no the computer has just been reset so which means all the sensors want have enough info to give the computer because of being reset sorry to break it to you.

the light is an emissions code in there sometimes its a oxygen sensor or the egr valve gets clogged in hondas...you need to retrieve the code to narrow the problem down
