Just realized my old code reader was giving me wrong codes

Been chasing a check engine light on my 2010 F-150 for two months. Bought a $40 scanner off Amazon years ago and it kept saying it was an O2 sensor. Swapped that out three times before a buddy brought over his Autel scanner and it pointed straight to a vacuum leak. Anyone else have a cheap tool that led you down the wrong path?

Cheap sensors work fine, cheap processors give garbage guesses.
