Output Speed Sensor Circuit No Signal (P0722)
DESCRIPTION
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 parking ...
