Learning why the check engine light is on can be extremely helpful, even if you’re not mechanically inclined. Sometimes, the problem is as simple as a dirty air filter or loose gasoline filler cap — easy fixes even for non-handy types. If the issue does require professional repair, vehicle owners can determine if the matter is urgent or whether they can continue driving for some time before addressing a repair.
Like many technologies, the price of OBD scanners has fallen to the point where they’re easily attainable by car owners who wish to purchase a unit, saving that trip to the mechanic or auto parts store. Basic models start at around $30 and go to several hundred dollars. Some mid-level OBD scanners will even translate the trouble codes to plain English rather than drivers having to look up an alphanumeric in a service manual or on the internet. Others can even suggest a plan of repair.
Besides facilitating diagnostics and repairs, an OBD port can also supply information about how a car is being driven. A dongle plugged into the OBD port is how certain auto insurance companies monitor their customer’s habits to determine if they qualify for a “good driver” discount. Similar products are also available at a retail level to monitor the driving patterns and location of family members, such as new teenage drivers, with the added benefits of a real-time display of the vehicle’s vitals and making preventative maintenance suggestions.
