P0713 Toyota Code - Transmission Fluid Temperature Sensor 'A' High Input

Quick Answer

The Automatic Transmission Fluid (ATF) Temperature Sensor converts the fluid temperature into a resistance value for use by the Engine Control Module (ECM). Common causes include Faulty Automatic Transmission Fluid (ATF) Temperature Sensor, Automatic Transmission Fluid Temperature Sensor harness is open or shorted, Automatic Transmission Fluid Temperature Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0713 Toyota Description

The Automatic Transmission Fluid (ATF) Temperature Sensor converts the fluid temperature into a resistance value for use by the Engine Control Module (ECM). The ECM applies a voltage to the temperature sensor. The sensor resistance changes with the ATF 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 increases. The ECM calculates the fluid temperature based on the voltage signal.
This Diagnostic Trouble Code (DTC) indicates an open or short in the ATF temperature sensor circuit. The ATF temperature sensor converts ATF temperature into an electrical resistance value. Based on the resistance, the ECM determines the ATF temperature, and the ECM detects an open or short in the ATF temperature circuit. If the resistance value of the ATF temperature is below 79 Ω*1 or higher than 156 kΩ*2, the ECM interprets this as a fault in the ATF sensor or wiring. The ECM will turn on the MIL and store the DTC.
