ELECTROHYDRAULIC CONTROL SYSTEM
Automatic Transmission
G: FRONT VEHICLE SPEED SENSOR
This vehicle speed sensor (output shaft speed sensor) is externally mounted on the transmission
case. It detects the front wheel speed and sends sine wave signals (1 6 pulses per rotation) to the
TCM.
The TCM converts the signals into pulse signals and outputs them to both the engine control mod-
ule (ECM) and the combination meter.
