P1723 SPEED SENSOR
DescriptionINFOID:0000000005928900
• The primary speed sensor is included in the control valve assembly.
• The secondary 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 primary speed sensor detects the primary pul ley revolution speed and sends a signal to the TCM.
