Output Shaft Speed (OSS) Sensor

WARNING: This page is about a different car, the 2004 Ford RV Cutaway, 2004 Ford Econoline, and 2004 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

The output shaft speed (OSS) sensor is a magnetic pickup, located at the output shaft ring gear, that sends a signal to the powertrain control module (PCM) to indicate transmission output shaft speed. The OSS sensor is used for torque converter clutch (TCC) control, shift scheduling and to determine electronic pressure control (EPC).
