Output Shaft Speed Sensor

WARNING: This page does not describe the selected car, but rather 13 other vehicles, including the 2003 Mazda B4000, 2003 Mazda B3000, 2003 Mazda B2300, 2002 Mazda B4000, and 2002 Mazda B3000. 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 on outside of transmission case at output shaft ring gear. See Figure. OSS sensor sends output shaft speed signal to PCM. OSS sensor is used for Torque Converter Clutch (TCC) control, shift scheduling and to determine EPC. Malfunctioning OSS sensor may cause harsh engagements, firm shift feel or abnormal shift schedule. Unexpected downshifts may occur at closed throttle. TCC may not engage.
