Bought a cheap code reader that gave me a ghost P0420 on a perfectly good cat
It sent me down a two hour diagnostic rabbit hole on a 2015 Civic, chasing a problem that wasn't there. What's your go-to scanner for quick, reliable codes?

Ever think about how the car's battery voltage can mess with cheap readers? A low or dirty power signal can make them spit out junk data like that ghost code. I always check the battery health first before I even trust what the scanner says.
