P0713 Transmission Fluid Temperature Sensor “A” Circuit High Input Level

P0713 – OBD-II Trouble Code Technical Description

Trouble code P0713 indicates a problem with the transmission fluid temperature sensor and the transmission fluid itself.

What does the fault code mean P0713?

Trouble code P0713 indicates a problem with the transmission fluid temperature sensor. This code usually appears when the transmission control module (TCM) detects too high a voltage, indicating that the transmission fluid temperature is too high. The sensor continuously monitors the temperature and sends a signal to the transmission control module (TCM). If the temperature rises too much, the TCM will determine that the transmission is overheated.

Fault code P0713.

Possible reasons

Some of the possible causes of the P0713 trouble code are:

  • Transmission fluid temperature sensor malfunction: The sensor itself may be damaged or fail, resulting in incorrect temperature readings and therefore too high a voltage.
  • Problems with wiring or connectors: The wiring or connectors connecting the temperature sensor to the control module (TCM) may be damaged, broken, or have poor contact, resulting in incorrect data and resulting in too high voltage.
  • Transmission overheating: Elevated transmission fluid temperatures can be caused by improper transmission operation or problems with the cooling system. This may cause the sensor to output a temperature value that is too high.
  • Transmission Control Module (TCM) malfunction: Problems with the control module itself can cause data from the temperature sensor to be misinterpreted, which can cause trouble code P0713 to appear.
  • Transmission problems: Some problems with the transmission itself can cause the fluid to overheat and therefore cause the P0713 code to appear.

These are just a few possible causes, and a detailed diagnosis of the transmission system is necessary to accurately determine.

What are the symptoms of a fault code? P0713?

Symptoms for DTC P0713 may include the following:

  • Check Engine Indicator: The appearance of the Check Engine light on your car's dashboard is one of the most common signs of a problem.
  • Irregular transmission operation: When the transmission fluid temperature is normal, you may experience irregular transmission operation such as jerking, hesitation, or improper shifting.
  • Increased transmission temperature: If the cause of the P0713 code is due to transmission overheating due to a malfunctioning cooling system, the driver may notice an increase in interior temperature or an overheating warning message.
  • Increased fuel consumption: Transmission malfunction caused by overheating or other problems can result in increased fuel consumption.
  • Speed ​​or power limitation: In some cases, the vehicle's control system may go into limp mode to prevent further damage to the transmission. This may limit the vehicle's maximum speed or power.

How to diagnose a fault code P0713?

To diagnose DTC P0713, you can follow these steps:

  1. Using the diagnostic scanner: First, connect a diagnostic scanner to the vehicle's OBD-II port and read the error codes. Verify that the P0713 code is indeed present.
  2. Checking the transmission fluid: Check the level and condition of the transmission fluid. The level must be within acceptable values, and the liquid must not be contaminated or overheated.
  3. Checking the temperature sensor: Using a multimeter, test the resistance at the transmission fluid temperature sensor at various temperatures. Compare the values ​​obtained with the specifications listed in the service manual.
  4. Checking wiring and connectors: Check the wiring and connectors connecting the temperature sensor to the transmission control module (TCM) for damage, corrosion, or poor connections.
  5. Checking the operation of the cooling system: Check the condition and operation of the transmission cooling system, including the radiator, thermostat and coolant pump. Make sure the system is working properly and is not causing the transmission to overheat.
  6. Additional diagnostics: If necessary, perform more detailed diagnostics on other transmission system components, such as solenoids, valves, and other sensors.
  7. Checking the Transmission Control Module (TCM): If necessary, perform diagnostics on the transmission control module to check its operation and interpret the signal from the temperature sensor.

After diagnosing and fixing the problem, reset the error code using a diagnostic scanner and check if the problem recurs. If you are not confident in your skills or do not have the necessary equipment to carry out diagnostics, it is recommended that you contact a qualified auto mechanic or auto repair shop.

Diagnostic errors

When diagnosing DTC P0713, the following errors may occur:

  • Misinterpretation of symptoms: One of the main mistakes is misinterpretation of symptoms. Some symptoms, such as irregular transmission operation or elevated temperatures, can be caused by a variety of things other than a faulty temperature sensor.
  • Insufficient temperature sensor check: Incorrectly measuring resistance or voltage on a temperature sensor may lead to incorrect conclusions about its condition. Insufficient testing of the sensor may lead to missing its actual malfunction.
  • Skipping wiring and connector checks: The wiring or connectors connecting the temperature sensor to the transmission control module (TCM) may be damaged or have poor contact. Skipping checks on these elements may result in missing their impact on the problem.
  • Incomplete diagnosis of the cooling system: If the problem is related to overheating of the transmission, insufficient diagnosis of the cooling system may lead to missing the cause of the overheating.
  • Ignoring other components of the transmission system: Certain transmission problems, such as problems with solenoids or valves, can also cause the P0713 code. Ignoring the possibility of a problem with other components of the transmission system may result in incorrect diagnosis and repair.
  • Faulty interpretation of diagnostic scanner data: Some values ​​obtained from the diagnostic scanner may be misinterpreted, which may lead to an incorrect diagnosis.

It is important to conduct a thorough and comprehensive diagnosis, considering all possible causes and components associated with the P0713 trouble code.

How serious is the fault code? P0713?

Trouble code P0713 should be taken seriously, although it is not critical or alarming. Here are some reasons why this code should be taken seriously:

  • Potential transmission problems: The P0713 code indicates a problem with the transmission fluid temperature sensor. Problems with the transmission system can cause the transmission to not operate properly, which in turn can cause additional wear or damage to transmission components.
  • Potential transmission overheating: High transmission fluid temperatures, which may be associated with code P0713, can cause the transmission to overheat. This can cause serious damage to the transmission and require expensive repairs.
  • Possible functionality limitations: In some cases, the vehicle's control system may place the vehicle into a limp mode to prevent further damage to the transmission. This may reduce vehicle performance and cause driver inconvenience.
  • Increased fuel consumption: Transmission problems caused by the P0713 code can result in poor performance and increased fuel consumption.

Although the P0713 code is not an emergency code, it does indicate potential problems that require attention and repair. If this code appears, it is recommended that you contact a qualified auto mechanic to diagnose and repair the problem.

What repair will help eliminate the code? P0713?

The repairs needed to resolve the P0713 trouble code will depend on the specific cause of the problem, some possible actions that may help correct this code are:

  1. Replacing the transmission fluid temperature sensor: If the transmission fluid temperature sensor has failed or is producing incorrect data, replacing the sensor may be necessary. This is usually a relatively simple and affordable procedure.
  2. Repair or replacement of wiring and connectors: If damage, breaks, or poor contacts are found in the wiring or connectors connecting the temperature sensor to the transmission control module (TCM), repair or replace them.
  3. Diagnostics and repair of the cooling system: If the cause of the P0713 code is due to transmission overheating due to problems with the cooling system, then the cooling system must be diagnosed and repaired. This may include replacing the radiator, thermostat, coolant pump, or other components.
  4. Checking and replacing the transmission control module (TCM): If other possible causes have been ruled out and the problem continues to occur, the transmission control module (TCM) itself may be faulty. In this case, it may need to be diagnosed and replaced.
  5. Additional repairs: Depending on your specific circumstances, additional repair work may be required on other components of the transmission or engine system.

After the repair is completed, it is recommended that you reset the error code using a diagnostic scan tool and take it for a test drive to see if the code appears again. If you are unsure of your skills or experience, it is recommended that you contact a qualified auto mechanic for diagnosis and repair.
