Should I buy one and have it plugged in while I drive?? I'm a little confused. Thanks for your quick response and all your help.
The TWC is the Catalytic Converter. F23A4 is an Accord ULEV engine.
The scan tool referred to is a Honda tool that allows them to scan your entire ECU and get all sorts of data. I believe you can purchase one but they're very expensive.
