P07A9 - OBD Trouble Code

<<See All OBD Codes

The trouble code P07A9 can be defined as Transmission Friction Element "D" Stuck On.

There are lot of friction elements required when a mechanical operation of an automatic transmission is being considered. The same friction materials like the clutch as used by the manual transmissions.

Here we are referring to the automatic transmission. One thing which you must keep in mind that its symptoms as well as causes would surely vary as it depends upon a number of things. Just keep in mind that the initial thing which should be considered is the general health of the automatic transmission as well as automatic transmission fluid.

It is always good to learn more! That is the reason why we are here to help you out in gaining more knowledge about the P07A9 error code.

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.

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

• Drop in the ATF
• There can be untidy friction element
• Grimy ATF
• Open, short, chafe, heat damage in the wiring
• The tire sizes might be raggy
• There can be problems which cause dissimilar rotational speed/circumference like low tire pressures, brake stuck on, etc
• Imprecise transmission control module
• Malfunctioning engine control module
• Module or harness might have water damage

Here are some steps which you should follow in order to diagnose this fault code:

You must always start with 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.

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

When you are attempting to search the connector/harness for this system, then you must find the junction connector. 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. 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 P07A9 Code

• Nonperformance of the internal transmission
• Failure in the transmission valve body solenoid
• Decrease in the transmission fluid level
