P2767

K41B CVT: CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM: P2767: Input / Turbine Speed Sensor "B" Circuit No Signal
P2767 - Input / Turbine Speed Sensor "B" Circuit No Signal

DESCRIPTION

The ECM detects the input shaft rotation speed based on the signal from the primary pulley speed sensor (transmission revolution sensor NIN) and performs gear ratio change control.





MONITOR DESCRIPTION

The ECM receives a signal from the primary pulley speed sensor (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 primary pulley speed sensor even while the vehicle is moving, it will conclude that there is a malfunction in the primary pulley speed sensor. The ECM will illuminate the MIL and set the DTC.
