P0710: Transmission Fluid Temperature Sensor Circuit Malfunction
2 vehicles · 2 makes · $50-$3,000 repair
Most Reported On
P0710 is an OBD-II diagnostic trouble code meaning “Transmission Fluid Temperature Sensor Circuit Malfunction.” This transmission code indicates a malfunction in the transmission fluid temperature (TFT) sensor circuit. That sensor tells the computer how hot the transmission fluid is so it can adjust shift timing, torque-converter lockup, and line pressure — and protect the transmission from overheating. The code sets when the temperature signal is implausible, out of range, or the circuit is open or shorted. Because the computer relies on this reading, you may notice harsh or delayed shifts, no torque-converter lockup, or the transmission defaulting to a protective strategy. This code is most commonly reported on 2000-2014 Ford E-Series, and 2012-2021 Nissan NV, with repair costs ranging from $50 to $3,000.
