Anyone had this issue?

Trying to get an emission test and this dang engine light turns on. Coolant is fine and everything seems to be working fine as well. Kind of a PIA knowing I need an emission test and they will fail due to this light being on. Anyone had this issue and what’s the fix? Engine light comes on and stays on for two days then goes away for a couple then back on again

Get it scanned for free at any parts store that does it or get a OB2 dongle from Amazon and scan it yourself.

Is it reaching temp like it normally would? Could be a sticky thermostat or low coolant...
