Best for Check engine lightreading and clearing codesemissions readinessused car checks

The most frustrating part of a check engine light is not knowing what it means. It could be a loose gas cap, or it could be something that needs a mechanic this week. A code reader plugs into the OBD2 port under the dashboard and tells you the trouble code, so you can look it up and decide what to do next.

The AD310 is a plain wired reader: no app, no phone, no subscription. It also shows readiness monitors, which tell you if the car is ready for an emissions test, and it can clear the light once the problem is fixed.

Pro tip Write the code down and check the freeze-frame data before you clear anything. Clearing the code also erases that snapshot, which is often the most useful clue about when and how the fault happened.
