We recommend Torque Pro The TFT (transmission fluid temperature) sensor is part of the automatic transmission fluid pressure (TFP) manual valve position switch and is a thermistor that changes value based on temperature. The TFT is an NTC (negative-temperature coefficient), which means that as the temperature increases, the resistance
decreases, and as the temperature decreases, the resistance increases. The PCM (powertrain control module) supplies a 5-volt reference signal to the sensor and measures the voltage drop in the circuit. When the transmission fluid is cold, the sensor resistance is high and the PCM detects high signal voltage. As the fluid temperature warms to a normal operating temperature, the resistance becomes less and the signal voltage decreases. This sensor is used by the PCM or TCM to detect the
temperature of the automatic transmission fluid. This signal is used to determine the best shift points and to regulate line pressure. It will cause the control module (PCM or TCM) to engage the TCC (torque converter clutch) sooner and disable overdrive, to help reduce the fluid temperature if it reaches higher than normal. NOTE: Whenever diagnosing a 700 series DTC (Diagnostic Trouble Code) with a transmission, transfer case or other driveline components, check for a
DTC under chassis and body systems, not just under “P” or powertrain/engine or emission control type codes. Module communications DTCs are “U” codes. These are most often found when looking for DTCs under chassis or body systems. Chassis related codes are labeled “C” and body system related codes are labeled “B” codes and these can cause drivetrain issues if they affect a sensor that is also used by the heating and air conditioning system.

P0710 Trans Fluid Temp Sensor A Circuit Malfunction PXNUMX Trans Fluid Temp Sensor A Circuit Malfunction PXNUMX Trans Fluid Temperature Sensor Circuit MalfunctionOBD-II DTC DatasheetTransmission fluid temperature sensor Electrical circuit malfunction What does this mean?This Diagnostic Trouble Code (DTC) is a generic transmission code, which means it applies to OBD-II equipped vehicles with a transmission fluid temperature sensor (Jeep, Ford, Nissan, Toyota, Honda, Infiniti, Acura, Jaguar, Lexus and t.D.). Although it is general, the exact repair steps may vary depending on the make / model. The transmission fluid temperature (TFT) sensor provides a signal that is used by the powertrain control module (PCM) to determine shift points, line pressure, and torque converter clutch (TCC) control. The sensor is often located in the transmission oil pan. The TFT sensor receives a reference voltage (typically 5 volts) from the PCM. It changes its internal resistance depending on the temperature of the transmission fluid in order to send a reverse voltage signal to the PCM. TFT sensors are a type of negative temperature coefficient (NTC) thermistor. This means that the internal resistance of the sensor is inversely proportional to the oil temperature. The TFT sensor signal voltage decreases when the transmission fluid temperature rises and vice versa. P0710 is set when the PCM detects a malfunction in the transmission fluid temperature sensor circuit.

Code severity and symptomsThe severity of this code is moderate to severe. In some cases, this code can indicate a transmission problem. It is recommended that you correct this code as soon as possible. Symptoms of a P0710 engine code may include:

Diagnostic and repair proceduresBegin by visually inspecting the transmission fluid temperature sensor and associated wiring. Look for loose connections, damaged wiring, etc. If damage is found, repair as needed, clear the code and see if it returns. Then check the technical service bulletins (TSBs) for the problem. If nothing is found, you will need to proceed to the step-by-step system diagnostics. The following is a generalized procedure as the testing of this code differs from vehicle to vehicle. To accurately test the system, you need to refer to the manufacturer's diagnostic flowchart. Pre-test the circuitUse a scan tool to monitor the transmission temperature sensor data parameter. Disconnect the TFT sensor; the scan tool value should drop to a very low value. Then connect the jumper across the terminals. If the scan tool now displays a very high temperature, the connections are good and the ECM can recognize the input. This means the problem is most related to the sensor and not the circuit or PCM issue. Check sensorDisconnect the transmission fluid temperature sensor connector. Then measure the resistance between the two terminals of the sensor with a DMM set to ohms. Start the engine and check the counter value; the values should decrease gradually as the engine warms up (check the engine temperature gauge on the dashboard to make sure the engine is at operating temperature). If the engine temperature rises but the TFT resistance does not decrease, the sensor is defective and must be replaced. Check circuitCheck the reference voltage side of the circuit: with the ignition on, use a digital multimeter set to volts to check the 5V reference voltage from the PCM at one of the two terminals of the TCM sensor. If there is no reference signal, connect a meter set to Ohm (with the ignition off) between the TFT reference terminal and the PCM reference terminal. If the meter reading is out of tolerance (OL), there is an open circuit between the PCM and the sensor that needs to be located and repaired. If the counter reads a numeric value, there is continuity. If everything is ok up to this point, you will want to check if 5 volts is coming out of the PCM at the voltage reference terminal. If there is no 5V reference voltage from the PCM, the PCM is probably defective. Check circuit ground.Connect a resistance tester (ignition off) between the ground terminal on the TCM sensor and the ground terminal on the PCM. If the meter reading is out of tolerance (OL), there is an open circuit between the PCM and the sensor that needs to be located and repaired. If the counter reads a numeric value, there is continuity. Finally, make sure the PCM has a good ground connection by connecting one meter to the PCM ground terminal and the other to the chassis ground. Once again, if the meter reads out of limits (OL), there is an open circuit between the PCM and ground that needs to be found and repaired. If everything in the chain is checked, there may be a problem with the transmission. This is especially true if the transmission fluid temperature codes are set in conjunction with other transmission codes. Related DTC discussions
