Something You should know about resetting the check engine light on Your 2014 Mazda CX5: if You haven't fixed the underlying issue, it's a very real possibility that the light will immediately come back on. With that said, there are a few different ways to reset it. If the issue is fixed, many codes will clear on their own; this will effectively reset the light. You can also try clearing the codes manually with an OBD-II scan tool, to see if that works. Alternatively, You may try disconnecting the negative terminal from the battery for a period of 5 or more minutes, or rapidly flicking the ignition between OFF and ON three times before starting the engine. While these may clear the codes and get rid of the illuminated light in the short term, there is no replacement for actually fixing the issue.
