P1723 CVT SPEED SENSOR FUNCTION
DescriptionINFOID:0000000003806458
The vehicle speed sensor CVT [output speed sensor (secondary speed sensor)] detects the revolution of
parking 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 the sig-
nal to the TCM.
