P150A GMC Meaning

The Vehicle Speed Sensor (VSS), also called the Output Shaft Speed Sensor (OSS) creates an AC voltage as the rotor passes through the magnetic field of the sensor. The Transmission Control Module (TCM) converts the AC into a vehicle speed signal, which is used to determine shift timing and Torque Converter Clutch (TCC) scheduling. The TCM also provides a Replicated Transmission Output Speed Signal (RTOSS) to the Engine Control Module (ECM)
