DTC P0712: Transmission Fluid Temperature Sensor "A" Circuit Low Input; DTC P0713: Transmission Fluid Temperature Sensor "A" Circuit High Input: Description
WARNING: This page is about a different car, the 2013 Toyota Camry. However, it is still accessible from the selected car via links, so may be relevant.
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 THO1 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.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| P0712 | ATF temperature sensor resistance is less than 79 Ω for 0.5 sec. or more (1-trip detection logic) |
|
| P0713 | ATF temperature sensor resistance is more than 156 kΩ for 0.5 seconds or more. Either of the following conditions is met (1 trip detection logic): |
|
| Condition (A): 394 seconds or more have elapsed after the engine start when engine coolant temperature or intake air temperature is -29.375°C (-20.875°F) or less. | ||
| Condition (B): 10 seconds or more have elapsed after the engine start when engine coolant temperature and intake air temperature are more than -29.375°C (- 20.875°F). |
