K313 CVT CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM P2767 Input / Turbine Speed Sensor "B" Circuit No Signal
DESCRIPTION
The ECM detects the input shaft speed based on the signal from the transmission revolution sensor (NIN) and performs gear ratio control.

MONITOR DESCRIPTION
The ECM receives a signal from the transmission revolution sensor (NIN) installed in the continuously variable transaxle and determines the input shaft speed in order to control the gear ratio. If the ECM detects no signal from the transmission revolution sensor (NIN) even while the vehicle is moving, it will determine that there is a malfunction in the transmission revolution sensor (NIN). The ECM will then illuminate the MIL and store this DTC.
