So I have a check engine light (Code P422) and my tabs are expired. I went and used the scan tool to reset the code and turn the check engine light off and went to get my car tested but I failed. They asked if i had recently reset my code and told me to drive 100 more miles and then come back. Well I was driving around for a bit (up to at least 100 miles) and while i was heading back to get my car retested my check engine light came back on. So my question is, is there a way or method to pass this test without actually fixing the problem right now? Would resetting the code then heading straight to the emissions place after work?

Do you guys have any knowledge about the whole "waiver fee" thing? it says if i fail a emissions test, I can go to a certified AES (Ecology Authorized Emission Specialist) and have them give me a waiver. But it also says that "Itemized receipts need to be provided that show that at least $150 was spent on emission diagnosis/repairs of the test failure."

So does that mean I just go to any certified AES place and basically just pay $150 to let them pass me on emissions?

I think it will be not so easy as you state.

Them emission tests are there to sort out cars not passing the test. So either you pass the test or do not get tags for the car anymore, rendering it useless.

That is the sole and only reason for them tests. It's not just the CEL, it is the whole ODBC system and sensor stuff. Just there to sort out cars not passing the emission test.

So I guess you need to fix the problem.

P0422 is the main cat below efficiency... that sucks dude. This isn't a part where you can find workarounds and try to squirrel your way into getting a smog pass.

You need to replace the bank 1 catalyst converter.

I can't take it to a certified AES shop and pay them the waiver diagnostic fee?

it says this on the washington vehicle emission check website and it states:

Q: Who can repair my vehicle if it fails its emission test?
A: Anyone can repair your vehicle. However, repair costs will only apply toward a waiver when an Authorized Emission Specialist (AES) performs the repairs.

Because some repairs may be very costly, your vehicle could be eligible for a waiver if it fails a retest.


Q: What if my vehicle fails a retest?
A: A waiver may be obtained at any Applus Test Station if an Ecology Authorized Emission Specialist (AES) has repaired the vehicle after the initial test failure.

Vehicles with missing or tampered emission control equipment will not be waived.

Itemized receipts need to be provided that show that at least $150 was spent on emission diagnosis/repairs of the test failure. Refer to the brochure given to you when the vehicle failed for additional information.

How does the car run otherwise?

Cats in this generation of car can break down, with the debris blocking the secondary cat, resulting in lowered fuel economy and reduced performance.

If you have any of those symptoms, then you should get the car replaced.

If not, then what you posted certainly suggests that once you drop the $150, you can request the waiver.

Good luck.
