P07A1 - OBD Trouble Code

<<See All OBD Codes

The trouble code P07A1 can be described as Transmission Friction Element "H" Slip Detected. 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.

Don’t worry if P07A1 error code is triggering again and again. We offer wide range of auto parts at affordable prices to our dear customers. 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 "H" Slip Detected?

• Flaws in the transmission control module
• Stained ATF
• There can be some quirks in the engine control module
• Problems related to wiring
• Issue of unequal tire sizes
• There can be less ATF
• The friction element might be worn out
• There can be unbalanced rotational speed/circumference
• Issue of water damage to module as well as harness

1. Powertrain Control Module - Do you remember when was the last time you got your car Powertrain Control Module checked up? A flawed Powertrain Control Module can cause a lot of issues like displaying P07A1 code.
2. Automatic Transmission Filter - Poor Automatic Transmission Filter can cause a lot of difficulties, so why not get it replaced at time?
3. Automatic Transmission Fluid - Are there some faults in your Automatic Transmission Fluid? Don’t waste time and get them replaced or else P07A1 code can turn up.
4. Body Control Module Component - OBD Code P07A1 can appear because of faulty Body Control Module Component.
5. Electronic Control Unit - Everything is fine with Automatic Transmission Fluid and still P07A1 code triggering? Then you must get your Electronic Control Unit checked.
6. Engine Control Module - There can be some issues with the Engine Control Module due to which you may see P07A1 code appearing over and over again. Visit us to buy best quality Engine Control Module online.
7. Auto Transmission Control Module - A lot of issues can arise do to defective Auto Transmission Control Module. Did you just see P07A1 code flashing? Now you know the reason why it is appearing. Get it inspected and replaced on time.

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

• It would be a great idea to 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
• You must find a junction connector when you are attempting to find the connector/harness for this system. There can be a "master" connector so just be sure that you are working with the right one by referring to your manual.
• The connector should be seated properly to ensure a good electrical connection. Where the connector is located on the A/T, it may be subject to vibrations that could cause connections to come 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 get rid of this code.

Common Mistakes When Diagnosing The P07A1 Code

• Negligence in the transmission valve body solenoid
• There can be some faults in the internal transmission
• Transmission fluid level might be less
