What does the P0707 code mean?

The P0707 code is a transmission range sensor circuit low input. It indicates that there is a problem with the transmission range sensor circuit, which is responsible for sending signals to the transmission control module.

This code can affect the performance of the vehicle and result in issues such as poor shifting, decreased fuel efficiency, and even transmission failure. On top of that, if the sensor can’t be properly powered, it may malfunction and you may not even be able to start your car at all.

This often happens in such cases since the control module can’t receive the sensor’s input on commanding the gears and gear shifts, so it can pose a big issue for your car.

What causes the P0707 code?

Even though the issue with this code is often caused by problems with the transmission range sensor’s circuit, there could be other issues at hand here. For you to properly figure out what’s causing this code, it’s necessary to consider all the listed reasons:

Faulty transmission range sensor

A faulty transmission range sensor is one of the most common causes of the code. The sensor may be damaged or worn out, resulting in incorrect or no signals being sent to the transmission control module.

Faulty wiring

Faulty wiring in the transmission range sensor circuit can also cause the P0707 code. This may be due to damaged or corroded wires, loose connections, or other electrical issues.

Failed transmission control module

A failed transmission control module can also cause the P0707 code. This component is responsible for receiving signals from the transmission range sensor and controlling the transmission’s shifting patterns. If it fails, it may not be able to receive the signals it needs to function properly.

Which car models does the P0707 code affect the most?

The P0707 code can affect many different car models, but some are more susceptible than others. Some of the car models that are most likely to be affected by the P0707 code include:

• Honda Accord: This vehicle is susceptible to this code due to a faulty design and placement of the transmission range sensor which causes it to wear off prematurely.
• Ford F-150: This one is another model that has faced quite a few reports on a faulty transmission range sensor which is why it’s often associated with this code.
• Dodge RAM: The RAM is yet another vehicle that faced pretty frequent issues with the code P0707 due to problems with electrical connections between the sensor and the TCM.

How to diagnose the P070 code

Diagnosing the P0707 code requires a series of steps and specialized tools. Still, it’s possible to diagnose the code with the simple help of the scanner tool and other DIY methods that we’ll go through:

Scan the vehicle for codes

The first step in diagnosing the code is to scan the vehicle for codes using a diagnostic scanner. This will provide you with the specific code and help you identify any other potential issues.

Check the transmission range sensor

If the scanner indicates the P0707 code, the next step is to check the transmission range sensor. This may involve removing the sensor and testing it with a multimeter or other diagnostic tools.

Check the wiring

If the transmission range sensor is working properly, the next step is to check the wiring in the circuit. This may involve using a wiring diagram to identify any potential issues, such as damaged or corroded wires.

Check the transmission control module

Finally, If the wiring checks out, you can also check the transmission control module. This may involve testing the module with a diagnostic tool or replacing it if it’s found to be faulty.

How to fix the P0707 code

Fixing the P0707 code may involve several different steps, depending on the underlying cause. Here’s an overview of the potential fixes for each cause:

Replace a faulty transmission range sensor

If the transmission range sensor is faulty, it may need to be replaced. This can be a relatively simple fix, but it may require special tools and diagnostic equipment.

Repair faulty wiring

In case the wiring in the transmission range sensor circuit is faulty, it may need to be repaired or replaced. This may involve identifying the specific wires that are causing the issue and repairing or replacing them.

Replace the failed transmission control module

The faulty TCM can also be a reason behind this code, although this happens rarely with this code. Still, it’s worth checking it and if the diagnostic test reveals that the faulty module is what caused the code to appear, you may have to replace it.

How to prevent the P0707 code

Preventing the P0707 code requires routine maintenance and care for the affected system. Here are some tips for preventing the code:

• Perform regular maintenance on the transmission range sensor and circuit
• Keep the wiring in good condition by inspecting it regularly and repairing any damage
• Avoid harsh driving and sudden shifts, as this can damage the transmission range sensor and circuit

By following these tips, you can help prevent the P0707 code from occurring and keep your vehicle running smoothly.

Our take

Overall, the P0707 code is a common issue that can affect the performance and safety of your vehicle. By understanding its meaning, causes, and fixes, you can diagnose and repair the issue quickly and effectively.

We hope that this guide will be just what you are looking for to fix the code and prevent it from happening again in your car.
