P07A3 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P07A3 can be explained as Transmission Friction Element "A" Stuck On. The amount of force which is required to help the vehicle steering when the ignition is ON and the supply of the voltage to the PSCM is above 6 volts, all other electric power-assisted steering sensors are operating accurately and the EPAS gear is providing assist is observed by the power steering control module.

Do you want to know more about the P07A3 fault code? Don’t worry! Parts Avatar Canada is here at your service. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model.

What causes this problem with the Transmission Friction Element "A" Stuck On?

• ATF might be low
• Tattered friction element
• ATF might be dirty
• There can be some issues related to the wiring
• Bumpy tire sizes
• The rotational speed/circumference may be unequal
• Defective transmission control module
• Malfunctioning engine control module
• There can be water damage to module and harness

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P07A3 code to be stored:

A good starting point is always a technical service bulletin search for your particular vehicle. Advanced diagnostic steps become very vehicle specific and may require the appropriate advanced equipment and knowledge to perform accurately. We include basic steps below but refer to a vehicle year/make/model/powertrain specific repair guide for specific steps for your vehicle.

Here is the Step 1

It is very important to follow the basic maintenance procedures accordingly at this point, as far as the transmission's health goes, start at the fluid. Your ATF (Automatic Transmission fluid) should be fully clean, free of debris and also, proper maintenance schedules have to be followed to avoid more defects. If you don’t remember the last transmission has been serviced (i.e. filter+fluid+gasket), it’s a good idea to perform this before continuing. There might be a bit of debris in your oil that is trapped internally. It may only take a simple service, so make sure you are aware of the last A/T service

Here is the Step 2

You must find a junction connector when you are attempting to find the connector/harness for this system. There may be one "master" connector so make sure you are working with the right one by referring to your manual. Make sure that the connector itself is seated properly to guard a fine electrical connection. Now when the connector is situated on the A/T, it may be subject to vibrations due to which the connections might become loose or physically damage them. Not to mention, the possibility of ATF to saturate connectors and wires causing future or present issues.

Here is the Step 3

All of us should be fully aware of the overall condition of your vehicle. Rough tires, worn out suspension parts, inaccurate wheels, all of these can and will cause issues in this system and possibly others as well, so even things out, and you may rid of this code.

Common Mistakes When Diagnosing The P07A3 Code

• Internal transmission might start failing
• Diminishing transmission fluid level
• Non observance of the transmission valve body solenoid
