What is ODO?

ODO refers to the mileage meter, which cannot be reset. Its main function is to inform the driver of the distance traveled. ODO trip meters are common types of numerical instruments that work by engaging the drive gear of the car counter with the speedometer gear. Due to the differences in models and brands, the display of the speedometer may also vary. ODO has the特点 that the upper gear runs a full circle, while the lower gear only runs one tenth of a circle. Similar to the speedometer, modern car trip meters are also available in electronic format and work by receiving trip signals from the speed sensor.
