Doesn’t show certain sensors and dtc’s – Engine Link - OBD II diagnosis Review

The app definitely works. Except I don’t get the codes showing in this app that I get when I take it to the automotive store. I’m guessing because it uses a generic OBDII list of trouble codes. I have P0327 which is a knock sensor low input that doesn’t show in this app. I also have an ABS sensor and and YAW sensor malfunction that doesn’t show up in Engine Link.
