• If you are a DIYer, then you can replace the defective O2 sensor for preventing possible damage to the catalytic converter. Taking it to the mechanic for this might cost thousands of dollars.

• On-board Monitor Test: Finds out if the engine has any misfire or compression problems on a particular cylinder, which aren’t severe enough to trigger a check engine light.
• You can save a lot of guesswork, and prevent emerging issues from causing a real driving problem, with no need to wait for days for certain OBD2 self-tests to run, and possibly turn the Check Engine Light on.

• EVAP Test: Checks fuel vapor leaks, including when there is a missing gas cap or a loose gas cap.
• You can start this test to prevent fuel from evaporating out of the tank and contributing to
