Output Speed Sensor
WARNING: This page is about a different car, the 2017 Chevrolet Spark. However, it is still accessible from the selected car via links, so may be relevant.
The output speed sensor is installed to convertor housing.
The output speed sensor detects the final gear speed. TCM evaluates the vehicle speed from the final gear revolution.
The output speed sensor generates an ON-OFF pulse signal according to the rotor speed. TCM judges the rotor speed from the pulse signal.
