Toyota Yaris XP210 (2020-2025) Reapir and Service Manual: 4WD/AWD Range Actuator Temperature Sensor Circuit Range/Performance Circuit Voltage Out of Range (C11411C)

DESCRIPTION When a malfunction has occurred in the AWD coupling solenoid system, the AWD ECU assembly stores DTC C11411C. DTC No. Detection Item DTC Detection Condition Trouble Area Warning Indicate Memory C11411C 4WD/AWD Range Actuator Temperature Sensor Circuit Range/Performance Circuit Voltage Out of Range Even though it can be inferred from the driving conditions that the coupling is generating a significant amount of heat, the temperature sensor value is approximately -10°C (14°F) for 1 second or more, and this continues despite the ignition switch being turned off and then ON again 2 times Even though the engine coolant temperature received from the ECM is less than 35°C (95°F), the temperature sensor value is fixed at 155°C (311°F) (short circuit condition), and this continues despite the ignition switch being turned off and then ON again 2 times The temperature sensor power source voltage is 0...
