Circuit No Signal; 2015 MY Tundra [08/2014 - ]
DTC
P0722
Output Speed Sensor Circuit No Signal
DESCRIPTION
SP2 coil as the parking gear mounted on the rear planetary gear assembly rotates, and this voltage is sent to the
ECM. The parking gear on the rear planetary gear is used as the timing rotor for this sensor.
The gear shift point and lock-up timing are controlled by the ECM based on the signals from this vehicle speed
sensor and the throttle position sensor signal.
