Transmission Speed Sensor: Description and Operation
The Pulse Signal Generator (PSG), also called the Turbine Shaft Speed (TSS) sensor, is a magnetic-pickup located on the side cover. It detects the idler
gear speed. There are 45 projections on the idler gear. As the idler gear rotates, the PSG produces an AC wave and sends it to the transmission control
module and the powertrain control module.
