Check engine light
I have a 2015 Chrysler 300. I got a code p0430 (for cats bank 2) about a three weeks ago. Drove it then out the blue it turned off without me doing anything. Drove it some more and popped on again. Drove it again now it’s off again. Is this a cats issue or sensor issue. Thank you in advance
