Transmission Speed Sensor: Description and Operation
Odometer
The OSS produces a maximum of 5000 readable pulses/mile between 5 and 161 km/h (3-120 mph), which are sent to the PCM to determine vehicle
speed. The vehicle speed input is used to determine the miles the vehicle has traveled. The PCM reads the OSS signal and sends vehicle speed
information to the BCM over the Class II link. The BCM in turn calculates the distance traveled and sends the information to the I/P cluster over the link.
The I/P cluster increments the electronic odometer accordingly.
