P2712 - OBD Trouble Code

<<See All OBD Codes

Is the car’s transmission continuously slipping along with sluggish acceleration? Is there a problem of decreased fuel economy along with vehicle not starting in the 1^st gear? Is the car’s check engine light illuminated on the dashboard? All these are an indication towards a problematic transmission system, thus resulting in OBD code P2712 error getting stored in the powertrain control module (PCM).

OBD code P2712 means Hydraulic Power Unit Leakage issue.

If the powertrain control module finds loss of pressure or reduced output due to potential leakage from the hydraulic power unit, OBD code P2712 gets stored. This may lead to faulty transmission shifts with occasional stalling and drivability issues.

What causes this problem with the Hydraulic Power Unit Leakage?

• Wrong level or dirty transmission fluid
• Failure inside transmission
• Clogged fluid filter or worn pump
• Blockage in transmission main control
• Faulty solenoid, torque converter clutch or internal blockage
• Faulty shift wirings or solenoids
• Faulty transmission control module
• Torque converter clutch faulty

1. Engine Control Module - Is your car engine light still staying ON after resetting or your car engine is turning off for no reason? Then these are some common symptoms indicating that your car engine control module is defective.
2. Powertrain Control Module - The PCM works as the central computer system in an automobile’s mechanism. This auto part is in charge of all the constituents as well as the functions performed by them. Having such enormous importance in the operation of all the parts means that any defect in it will affect almost every aspect of a car.
3. Electronic Control Unit - The ECU is a major component of your car's onboard computer. It's used to regulate many systems and subsystems in your car's engine, drive train and other major components. Visit us to buy best quality ECU online.
4. Diagnostic Tools - Take the help of a professional mechanic to diagnose OBD code error. Use high grade diagnostic tools to resolve this issue. Buy new tools and equipment form us!
5. Automatic Transmission Solenoid - If the solenoid is damaged, the gear shifts may be delayed causing drivability issues. Thus, replace it now!
6. Transmission Control Module - The TCM monitor the transmission system of the vehicle and if it becomes faulty, the vehicle will have transmission performance issue. Thus, replace and reprogram it now!
7. Automatic Transmission Sensor - It is important to note that the transmission sensor plays a vital role in the working of the TCM in relation to the PCM as well. Thus, replace faulty sensors now!
8. Automatic Transmission Connector - Faulty or damaged connectors will cause performance issues and thus should be replaced at first instance for proper functioning of the PCM and the TCM.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P2712 here:

Common Symptoms

• Harsh shifting
• Transmission slippage
• Transmission overheating
• Decreased fuel efficiency
• An OBD stored code in the PCM
• Illuminated malfunction indicator lamp

Here are some ways with the help of which you will be able to correct the OBD Code P2712.

• Checking for transmission fluid or changing the transmission fluid
• Defective shift solenoid replacement
• Replacing or reprogramming Transmission Control Module
• Faulty wiring and/or connectors for a damaged transmission control circuit replacement

We have high grade Transmission, PCM, Pressure Control Solenoid, Transmission Fluid, Transmission Control Module, Electronic Pressure Control Solenoid, Pressure Gauge, Connector, Shift Solenoids, Transmission Module, Electronic Pressure Regulator, Transmission Cooler and a lot more for our precious customers.

Here are some steps which you should follow in order to diagnose this P2712 fault code:

• Make use of a digital volt ohm meter (DVOM) for the complete test. Continue through the tests until the problem is confirmed. You will also need a basic OBD code scanner to reset the computer and erase the code.
• First check the level and quality of the transmission fluid. If the fluid is low, add more and retest the system.
• If the transmission fluid appears dirty or contaminated, and/or it smells burnt, the mechanic will flush the system, change the transmission fluid, clear the code, and retest once more.
• Inspect and test the transmission for internal mechanical problems, circuit problems, and issues with the shift solenoid. After each repair, they will clear all codes and retest the vehicle to see if the P2712 code appears again.

Common Mistakes When Diagnosing the P2712 Code

The most common mistake while diagnosing P2712 code is misdiagnosis of an engine misfiring issue or a problem with the vehicle’s driveline. If the system is not thoroughly inspected and diagnosed, it can also look like an internal transmission problem when it’s actually a much simpler and less expensive issue.
