U660E AUTOMATIC TRANSMISSION / TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: P0711: Transmission Fluid
Temperature Sensor "A" Performance
P0711 - Transmission Fluid Temperature Sensor "A" Performance
DESCRIPTION
The Automatic Transmission Fluid (ATF) temperature sensor converts the fluid temperature into a resistance value for use by the TCM.
The TCM applies a voltage to the temperature sensor through terminal OIL of the TCM.
The sensor resistance changes with the transmission fluid temperature. As the temperature becomes higher, the sensor resistance decreases.
One terminal of the sensor is grounded so that the sensor resistance decreases and the voltage goes down as the temperature becomes higher.
The TCM calculates the fluid temperature based on the voltage signal.
MONITOR DESCRIPTION
This DTC indicates that there is a problem with output signals from the automatic transmission fluid (ATF) temperature sensor and that the sensor
itself is defective. The ATF temperature sensor converts the ATF temperature into an electrical resistance value. Based on the resistance, the TCM
determines the ATF temperature and detects an open or short in the ATF temperature circuit or a fault of the ATF temperature sensor.
After running the vehicle for a certain period, the ATF temperature should increase. If the ATF temperature is below 20锟斤拷C (68锟斤拷F) after running the
vehicle for a certain period, the TCM interprets this as a fault, and turns on the MIL.
