P2712 OBD-II Trouble Code: Hydraulic Power Unit Leakage Intermittent

check engine light

P2712 code definition

The P2712 Trouble Code refers to hydraulic power unit leakage intermittent.

What the P2712 code means

When the powertrain control module finds that there is low pressure or potential leakage in the hydraulic power unit, this code will appear. The hydraulic power unit controls the transmission, and when there are issues, it can cause a number of issues with the vehicle.

What causes the P2712 code?

A number of things can cause the P2712 code to appear. Here are the most common reasons:

  • Internal hydraulic leaks of the transmission fluid.
  • Faulty electronic pressure control solenoid.
  • The internal transmission fluid passages might have hydraulic blockage.
  • Transmission failures.
  • Low transmission fluid.
  • Dirty transmission fluid.
  • Faulty powertrain control module or transmission module.

What are the symptoms of the P2712 code?

The symptoms associated with the P2712 code can vary greatly. In some cases, there might not be any noticeable symptoms at all. In other cases, the engine might stall when the vehicle comes to a stop or when the vehicle is idling. It might become more difficult to shift, and the transmission might slip and even overheat. Often, the fuel efficiency will be decreased as well. Many will also have a malfunction indicator light or Check Engine Light that illuminates. The code will be stored, and it might be accompanied by a number of other codes as well as including transmission slippage codes, shift solenoid codes, torque converter clutch codes, lock up codes, and gear ratio codes.

How does a mechanic diagnose the P2712 code?

The mechanic will want to start with their OBD-II scanner in most cases, although some might do the visual inspection first. When they hook up their scanner to the vehicle’s onboard computer, they will access the data that is stored on the vehicle’s onboard computer. This can help to make the process of diagnosing the problem and figuring out the correct repairs much easier.

Common mistakes when diagnosing the P2712 code

One of the most common mistakes during the diagnosis of the P2712 code is that the technicians overlook wiring issues and problems with the electronic pressure control solenoid. They make other repairs instead, such as replacing high pressure pumps when it is not necessary. It is important that the technicians take their time with the diagnosis and that they look at all of the potential issues, and work their way up from the smaller potential issues.

How serious is the P2712 code?

A vehicle that has the P2712 code stored could find quite a few serious issues to contend with. Not only will it have lower fuel efficiency, but will also fail to perform well. Vehicles with this code have issues idling and accelerating, and this can be quite a problem. Even those that do not have these issues, but which still have the code in their vehicle need to get in touch with a qualified mechanic who can examine and diagnose the vehicle and then provide the proper repair.

What repairs can fix the P2712 code?

Located below are some of the repairs that the mechanics may utilize to fix the P2712 code.

  • Check all of the electrical connections and make repairs or replacements as needed.
  • Add transmission fluid.
  • Check for contaminated transmission fluid and flush the system.
  • Rebuild or replace the transmission.
  • If the powertrain control module is at fault, they will replace it.

Additional comments for consideration regarding the P2712 code

It is important that you take proper care of your vehicle. Even if you do not notice any difference in the performance of your car or truck while you are driving, if you have a P2712 code, there could be a number of problems under the hood. Take the vehicle to a mechanic and have it diagnosed and repaired. This will give you more peace of mind while you are on the road.
