OUTPUT SPEED SENSOR DESCRIPTION The Input and Output Speed Sensors (Fig. 230) are two-wire magnetic pickup devices that generate AC sig- OPERATION The Input Speed Sensor provides information on how fast the input shaft is rotating. As the teeth of The Output Speed Sensor generates an AC signal in a similar fashion, though its coil is excited by rota- The TCM compares the input and output speed signals to determine the following: • Transmission gear ratio • Speed ratio error detection • CVI calculation the engine speed signal to determine the following: • Torque converter clutch slippage • Torque converter element speed ratio REMOVAL (1) Raise vehicle. transmission. (3) Remove the wiring connector from the output speed sensor (2) (Fig. 231). NOTE: The speed sensor bolt has a sealing patch (4) Remove the bolt holding the output speed sen- sor to the transmission case. (5) Remove the output speed sensor (2) from the transmission case. INSTALLATION (1) Install the output speed sensor (2) (Fig. 232) into the transmission case.
