DTC P0710 Transmission Fluid Temperature Sensor "A" Circuit; 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 2008 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
The Automatic Transmission Fluid (ATF) temperature sensor converts the ATF temperature into a resistance value which is input into the ECM.
The ECM applies a voltage to the temperature sensor through ECM terminal THO1.
The sensor resistance changes with the ATF temperature.
One terminal of the sensor is grounded so that the sensor resistance and voltage decrease as the temperature becomes higher.
The ECM calculates the ATF based on the voltage signal.
DTC DETECTION CONDITION AND TROUBLE AREA REFERENCE
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| P0710 | ATF temperature sensor resistance changes from (a) to (b) or from (b) to (a) in less than 0.5 sec, and P0712 and P0713 are not detected (1 trip detection logic):
|
|
| P0712 | ATF temperature sensor resistance is less than 79 Ω for 0.5 sec. or more (1 trip detection logic) |
|
| P0713 | 15 minutes or more after the engine start, ATF temperature sensor resistance is more than 156 kΩ for 0.5 sec. or more (1 trip detection logic) |
