Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
DTC P0714: ATF Temperature Sensor Intermittent Failure: General Description
The ATF temperature sensor is a thermistor type sensor that changes resistance according to the change in ATF temperature. The powertrain control module (PCM) sends a 5 V reference voltage to the sensor through a pull-up resistor. When the ATF temperature is low, the sensor resistance increases and the PCM detects a high signal voltage. As the ATF temperature rises, the sensor resistance decreases and the PCM detects a low signal voltage. When the engine is stopped and enough time has passed, the ATF temperature will equalize to the engine coolant temperature. When the temperature in the ATF temperature sensor deviates from the temperature in engine coolant temperature (ECT) sensor 2 after the engine is stopped and enough time has passed, the PCM detects a malfunction and stores a DTC.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
