P079B OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P079B can be explained as Transmission Friction Element "B" Slip Detected. If there are some issues with the internal friction materials in the automatic transmission, it will then lead to unpredictable driving conditions as far as shift timing, torque output and many other complications. Internal slippage can be caused due to uncommon paired tires, insufficient inflated tires.

Do you want to know more about the P079B fault code? Don’t worry! Parts Avatar Canada is here at your service.

The letter “B” in this case might refer to some possible differences. The person might be dealing with a particular circuit/wire or there can be a certain friction element within the transmission. That is the reason why it is very important to have a look at your service manual for particular locations, distinctions, and other such specifications. When the engine control module would detect a slip in the internal "B" friction element inside the transmission, then P079B code would start appearing.

What causes this problem with the Transmission Friction Element "B" Slip Detected?

• ATF might be dirty
• Bumpy tire sizes
• ATF might be low
• Tattered friction element
• Malfunctioning engine control module
• The rotational speed/circumference may be unequal
• Defective transmission control module
• There can be some issues related to the wiring
• 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 P079B 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. Here are some basic steps below but refer to a vehicle year/make/model/powertrain specific repair guide for specific steps for your automobile.

Here is the Step 1

The general maintenance procedures should be carried out on a regular basis, as far as the transmission's health goes, start at the fluid. Your 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, it would be a nice 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 you must remember the last time you got your A/T service done.

Here is the Step 2

You will have to search for a junction connector while you are trying to find the connector/harness for this system. There may be one "master" connector so just make sure that you are working with the right one by referring to your manual. Just be sure that the connector itself is seated properly to ensure a perfect electrical connection. Now when the connector is situated on the A/T, it might be subject to vibrations that could cause connections to come loose or physically damage them. The possibility of ATF to saturate connectors and wires causing future or present troubles.

Here is the Step 3

The overall condition of your vehicle matters a lot, and that is the reason why we should be fully aware regarding it. Uneven tires, tattered suspension parts, incorrect wheels, all of these can and will cause problems in this system and possibly others as well. So make sure that you repair or replace the faulty parts and then this trouble code would stop triggering.

Common Mistakes When Diagnosing The P079B Code

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