Diagnostic Fault Information
Typical Scan Tool Data
Circuit/System Description
The output speed sensor (OSS) is a hall-effect type sensor. The sensor faces the front differential transfer drive gear. The sensor receives 8.3-9.3
volts on the OSS supply voltage circuit from the transmission control module (TCM). As the output shaft rotates, the sensor produces a signal
frequency based on the machined surface of the output shaft. This signal is transmitted through the OSS signal circuit to the TCM. The TCM uses
the OSS signal to determine line pressure, transmission shift patterns, torque converter clutch (TCC) slip speed and gear ratio.
