The Innova 3040e is an advanced model of the Innova 3040. The 3040e scan tool is more sleek and compact than the 3040 model. Also, the Innova 3040e diagnostic car scan tool is able to perform an oil light reset, while the Innova 3040 code reader cannot.

The two code readers that we have discussed above are easy to use with a large screen display, are affordable, and will let you know why the check engine light is on.
