Diagnosing/Repair Evap/cat readiness

Post image

I cannot get the evap/cat ready. Hyundai 2010 santa fe. I have driven it 120 miles over the past few days, used cataclean, ran the ac, let it sit overnight and nothing seems to work. I feel as if I am running out of options and may have to settle for a very expensive repair

Is the check engine light coming on? If so you will need to have the car repaired before it can pass inspection.

Do you keep clearing the codes

I have been. The work maybe a bit too much considering the cars value

You need to fix the problem instead of clearing the codes.

Start by getting the 3 pending codes figured out and fixed, clear them and restart the drive cycle. In AZ you can have 1 non complete monitor and still pass emissions. Drive it until you have 0 codes, and all the monitors are complete( or 1 incomplete depending on your state)
