Honestly, it's been 4 years. A lot can happen in 4 years. Not to mention, this does not indicate the same part has failed. An AutoZone "diagnostic tool" does not perform actual diagnostics, just pulls trouble codes. It's really not going to give you the information you really need. I would absolutely seek diagnostic testing by a trusted technician.
