What does the P0713 code mean?

The P0713 code is a generic powertrain code that relates to the transmission fluid temperature sensor circuit. This code is triggered when the powertrain control module (PCM) detects that the transmission fluid temperature sensor is not functioning properly. The transmission fluid temperature sensor is responsible for relaying information to the PCM about the temperature of the transmission fluid, which is crucial for ensuring the transmission is functioning properly.

If the P0713 code appears, it is important to take action to diagnose and repair the issue as soon as possible. Ignoring the code can lead to further damage to the transmission and potentially costly repairs down the line.

What causes the P0713 code?

There are several common reasons behind the code P0713 and it’s worth checking all of them to prevent having to deal with transmission repairs. Here’s a list of the most common suspects that could be triggering the code in your car:

Faulty transmission fluid temperature sensor

A faulty transmission fluid temperature sensor is the most common cause of the P0713 code. Over time, the sensor can wear out or become damaged, which can lead to inaccurate readings being sent to the PCM.

Symptoms that may be present with a faulty transmission fluid temperature sensor include erratic shifting, poor fuel economy, and a check engine light.

Faulty wiring or connections

Faulty wiring or connections in the transmission fluid temperature sensor circuit can also trigger the P0713 code. This can occur due to damage to the wiring or loose connections.

Symptoms that may be present with faulty wiring or connections include intermittent shifting issues and sporadic check engine light illumination.

Issues with the transmission control module

In some cases, the P0713 code may be triggered due to issues with the transmission control module (TCM). The TCM is responsible for regulating the transmission fluid temperature sensor, and if it is not functioning properly, this can cause the P0713 code to appear.

Symptoms that may be present with faulty TCM include inconsistent shifting and poor performance.

Which car models does the P0713 code affect the most?

The P0713 code can affect a wide range of car models, but it is most commonly found in vehicles with automatic transmissions. Some car models that are known to have issues with the P0713 code include the following:

• Honda Civic: Some Honda Civic models, particularly those produced between 2001 and 2003, have been known to experience issues with the automatic transmission, including problems related to gear shifting and slipping.
• Toyota Corolla: Certain models of the Toyota Corolla, such as the 2003 and 2004 models, have been reported to have issues with the transmission. These issues can include problems with shifting gears, as well as slipping or jerking while driving.
• Nissan Altima: The Nissan Altima is another car that has been known to experience issues with the automatic transmission. Some drivers have reported problems with slipping gears, difficulty shifting, and other issues related to the P0731 code.

How to diagnose the P0731 code

Diagnosing the P0713 code requires specialized diagnostic tools and equipment. Here are the steps to diagnose the code:

Use a scan tool to retrieve the code

The first step in diagnosing the P0713 code is to use a scan tool to retrieve the code from the PCM. This will provide information about which system is malfunctioning and help guide the diagnostic process.

Inspect the transmission fluid temperature sensor

The next step is to inspect the transmission fluid temperature sensor for damage or wear. If the sensor appears to be functioning properly, it may be necessary to test the wiring and connections in the sensor circuit.

Test the sensor circuit

Using a multimeter, test the wiring and connections in the sensor circuit to ensure that they are functioning properly. If there is an issue with the wiring or connections, this will need to be repaired or replaced.

Test the TCM

If the sensor and wiring are functioning properly, it may be necessary to test the TCM to ensure that it is functioning properly. This will require specialized diagnostic equipment and expertise.

How to fix the P0731 code

The specific steps to fix the P0713 code will depend on the underlying cause of the issue. Here are some potential fixes:

Replace the transmission fluid temperature sensor

If the sensor is faulty, the most common fix is to replace it with a new one. This is a relatively simple and straightforward repair that can often be completed in a single visit to the mechanic.

Repair or replace the wiring or connections

If there is an issue with the wiring or connections, the affected parts will need to be repaired or replaced. This is a more complex repair that may require more time and expertise.

Replace the TCM

If the TCM is at fault, it will need to be replaced. This is a more involved repair that may require specialized diagnostic equipment and expertise.

How to prevent the P0731 code

Performing routine maintenance can sometimes be enough to prevent the code P0731 from occurring again, so here’s what you can do to maximize your prevention chances:

• Changing the fuel filter on time
• Checking up on the transmission fluid level
• Making sure that the transmission is working properly
• Driving carefully to reduce the stress put on the transmission

If you notice any symptoms of an issue with the transmission, such as erratic shifting or poor performance, it is important to seek professional help as soon as possible. Ignoring these symptoms can lead to further damage to the transmission and potentially costly repairs down the line.

Our take

In conclusion, the P0713 code can indicate a range of issues with a vehicle’s transmission, but with proper diagnosis and repair, it can be resolved. By understanding the potential causes of the code, which car models are most affected, and how to diagnose and fix the issue, you can take steps to ensure that their vehicles are functioning properly and reduce the risk of costly repairs down the line.
