Genesis COUPE BK 2010, Manual

Page: 28 / 168

The automatic transmission fluid(ATF) temperature sensor A is installed in the INHIBITOR SWITCH and fluid(ATF)
temperature sensor B is installed in the valve body. The TCM supplies a 5V reference voltage to the sensor, and the output
voltage of the sensor changes when the ATF temperature varies.
This DTC is for checking sensor failure. This code is set if the temperture data from Oil Temperture sensor is fixed between -
20°C and 0°C or 0°C and 20°C for 10min. after driving a vehicle.
