DTC Advanced Diagnostics: P0710
DTC P0710:CVT Fluid Temperature Sensor (Out of Range)

General Description

The transmission fluid temperature sensor is a thermistor type sensor that changes resistance according to the change in transmission fluid temperature. The powertrain control module (PCM) sends a 5 V reference signal to the sensor through a pull-up resistor. When the transmission fluid temperature is low, the sensor resistance increases and the PCM detects a high signal voltage. As the transmission fluid temperature rises, the sensor resistance decreases and the PCM detects a low signal voltage. When the transmission fluid temperature sensor signal voltage to the PCM is a specified range for a specified time, the PCM detects a malfunction and stores a DTC.

None.

Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the PCM memory. If the malfunction returns in the next (second) drive cycle, the MIL comes on, the shift position indicator blinks, and a Confirmed DTC and the freeze data are stored.

Conditions for clearing the DTC
The shift position indicator comes off by turning the vehicle to the OFF (LOCK) mode. The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the 12 volt battery.
