tion speed as input signal, TCM changes the operating pr essure of the primary pulley and the secondary pul-
ley and changes the groove width of the pulley to control the gear ratio.

Description INFOID:0000000004667046
• The input speed sensor (primary speed sensor) is included in the control valve assembly.
• The vehicle speed sensor CVT [output speed sensor (s econdary speed sensor)] detects the revolution of the
idler gear and generates a pulse signal. The pulse signal is sent to the TCM, which converts it into vehicle
speed.
• The input speed sensor (primary speed sensor) detects the primary pulley revolution speed and sends a sig-
nal to the TCM.
