DTC P0722 OUTPUT SPEED SENSOR CIRCUIT NO SIGNAL

CIRCUIT DESCRIPTION

DTC Detection Condition:

The speed sensor SP2 detects the rotation speed of the transmission output shaft and sends signals to the ECM. The ECM determines the vehicle speed based on these signals.

An AC voltage is generated in the speed sensor SP2 coil as the rotor mounted on the output shaft rotates, and this voltage is sent to the ECM.

The gear shift point and lock-up timing are controlled by the ECM based on the signals from this speed sensor and the throttle position sensor signal.
