DTC P0710	Transaxle fluid temperature (TFT) sensor circuit malfunction (short to ground/open circuit)
DETECTION CONDITION	• If the PCM detects either of following conditions for 100 s or more, the PCM determines that the TFT sensor circuit has a malfunction. - TFT sensor voltage is 0.1 V or less and vehicle speed 20 km/h {12 mph} or more. - TFT sensor voltage is 4.9 V or more and vehicle speed 20 km/h {12 mph} or more. Diagnostic support note: • This is a continuous monitor (CCM). • The MIL illuminates if the PCM detects the above malfunction conditions during the first drive cycle. • A PENDING CODE is not available. • FREEZE FRAME DATA is available. • The O/D OFF indicator light illuminates. • The DTC is stored in the PCM memory.
