How does a transmission fluid temperature sensor work?
Thermometrics Transmission Fluid Temperature Sensor (TFT) measures the temperature of transmission fluid. It provides input to the control module to modify shift patterns for smoother shifting in automatic transmissions, and also provides over-temperature protection by locking the torque convertor.
What type of variable resistor are transmission fluid temperature sensors?
Another input the PCM uses when controlling the shifting of an electronically controlled transmission is the transmission fluid temperature (TFT) sensor. Most TFT sensors are a type of resistor called a thermistor. A thermistor changes its resistance based upon its tem- perature.
When to use the transmission fluid temperature code p0713?
Code P0713 is set when the PCM detects a high transmission fluid temperature sensor signal. This usually indicates an open circuit. An example of a transmission fluid temperature sensor: Related trans fluid temperature sensor “A” circuit codes: P0710 Transmission Fluid Temperature Sensor A Circuit Malfunction
What does DTC p0713 mean on the TFT sensor?
When the PCM detects a continuous open or short to power in the TFT signal circuit or the TFT sensor, then DTC P0713 sets. DTC P0713 is a type C DTC. The system voltage is 8-18 volts. The ignition is ON. The TFT sensor indicates a signal voltage greater than 4.92 volts for 409 seconds (6.8 minutes).
What does the OBD code p0713 stand for?
As temperatures increase, so does voltage which the TCM will read as an overheating transmission. P0713 is an OBD-II generic code for a voltage problem with the automatic transmission temperature sensor.
What causes a transmission temperature sensor to malfunction?
P0713 Possible Causes 1 Faulty Transmission Fluid Temperature Sensor 2 Transmission Fluid Temperature Sensor harness is open or shorted 3 Transmission Fluid Temperature Sensor circuit poor electrical connection

When is the transmission fluid temp sensor a circuit?
Error Code P0713 is set when the PCM detects a high transmission fluid temperature signal, which suggests an open circuit issue. If this code is stored, the TCM (transmission control module) is reading voltage that is too high for the parameters set by the manufacturer, which means the automatic transmission fluid is too hot.
