Engine light

Compared to other code readers in the market, the AUTOPHIX OM126P provides fast reading and clearing of emission-related codes.

The stream live sensor data supports the Evaporative Control System that helps identify system leaks. The sensors display relevant information such as the air/fuel mixture and temperature.


One of the main reasons that the check engine light comes on is a failed oxygen sensor. The AUTOPHIX OM126P scanner enables you to stream your vehicle’s Oxygen values to prevent any future errors.
