P0714 OBD-II Trouble Code: Transmission Fluid Temperature Sensor Circuit Intermittent

P0714 code definition

The P0714 Trouble Code indicates transmission fluid temperature sensor circuit intermittent.

What the P0714 code means

When the powertrain control module finds that a transmission temperature is not within the range determined by the manufacturer, this code will often appear. The code will be stored, and the malfunction light will illuminate.

What causes the P0714 code?

A number of things can cause the appearance of the P0714 code. The following are some of the most common causes of the P0714 code:

• Low transmission fluid, which could indicate that you have a transmission fluid leak.
• Faulty transmission.
• Slipping transmission.
• Overheating engine.
• Faulty transmission temperature sensor.
• Faulty powertrain control module, but this is rare.

What are the symptoms of the P0714 code?

When the code appears, it gets stored, and the Check Engine lamp will also illuminate. It will likely stay lit. In addition, drivers will usually smell transmission fluid that has been overheated. The transmission might start to smoke as well. Drivers might also notice that the transmission slips, or that it doesn’t engage. This can be a big problem, naturally, so it is important to make sure you have a mechanic check the transmission before you drive the vehicle any further.

How does a mechanic diagnose the P0714 code?

The mechanic will use their OBD-II scanner to check the vehicle. They connect it to the vehicle’s onboard computer, which has gathered data about the vehicle. This information makes it easier for the mechanic to diagnose the vehicle properly. Since this issue is dealing with the transmission, they will want to test the vehicle to see what the issue might be rather than just relying on the code. They may reset the code to see if it returns when they are testing the vehicle. It is important for the mechanic to pay special attention to the transmission when these and related codes are present.

Common mistakes when diagnosing the P0714 code

Some mechanics may misdiagnose the issues as a leaking transmission. While it is possible that it is the case, there could be other issues at play as well. The low fluid could have caused other parts of the transmission to be damaged, so the mechanic needs to pay close attention to the transmission to find the real problem.

How serious is the P0714 code?

The P0714 code is extremely serious, and it means that your car could well be in for a world of trouble. If you do not get it checked out and repaired, not only will your vehicle not run well, it might not run at all. If the transmission goes on the vehicle, you can’t drive it until it is rebuilt or replaced. You will want to make sure that you bring your vehicle to a mechanic as soon as possible if you have this sort of issue.

What repairs can fix the P0714 code?

The following are some repairs that might be needed in order to fix the P0714 code:

• Use the OBD-II scanner to diagnose the vehicle and make sure the code is legitimate.
• Check for transmission fluid leaks and low fluid levels.
• Check wiring and connections, and make any needed repairs.
• Rebuild or replace the transmission if it has serious problems.
• If there is nothing wrong with the transmission, it could be the powertrain control module, although this is a rare occurrence.

Additional comments for consideration regarding the P0714 code

A damaged transmission is a serious problem for any vehicle. If you have this code present, or any transmission related code, you can’t delay in having a mechanic look over your vehicle and perform the needed repairs. If you continue to drive, the transmission will eventually fail. Taking care of the problem as soon as you can is always the best solution.
