Error Code P2729: What It Means & What To Do?

OBD Code P2729 - Pressure Control Solenoid "E" Control Circuit Low

<<See All OBD Codes

What does P2729 error code signify? What are the symptoms and causes? This type of error code usually appears in the vehicle if the transmission refuses to shift properly and is known as pressure control solenoid "E" control circuit low. In order to control the hydraulic pressure in the transmission, the pressure control solenoids are used by the transmission control module. This is generally used to apply clutch in the transmission with several gear ratios so that the vehicle moves smoothly down the road. The P2729 error will be stored, if the TCM detects an issue with the solenoid which is not performing as needed.

This is a common type of trouble code and is applicable to the vehicle with automatic transmission. This is limited to vehicles like Ford, GMC, Chevrolet, Honda, BMW, Saturn, Land Rover, Acura, Nissan, Saturn, etc. though it is common, the repair process will vary based on the make, model and year of configuration. If the P2729 error is found, it means the PCM has found a problem with the pressure control solenoid "E" control circuit. The error is found depending on the specific error that is found by the PCM. An automatic transmission is operated by bands and clutches that will make changes to the gears by placing fluid pressure at the right place and time.

 

What causes this problem with Pressure Control Solenoid "E" Control Circuit Low?

 

  • The level of transmission fluid is less.
  • The transmission fluid might be polluted.
  • Either the TCM or the PCM might be faulty.
  • Failure of mechanical transmission.
  • Though the pressure might be fine, the faulty electronic pressure control solenoid might show up this error code.
  • The pressure might be built up due to hydraulic blockage which takes place inside the passage of the internal transmission fluid.

Replace/Repair These Parts To Fix OBD Code P2729

  1. Powertrain Control Module - Does your engine turn off without any reason? Then it’s a high time to replace your PCM as it can be faulty.
  2. Pressure Control Solenoid - Replacing the defective pressure control solenoid can help your system function normally.
  3. Transmission Control Module - Does the check engine light blink very often? Then the TCM can be damaged which needs replacement to avoid P2729 error.
  4. Automatic Transmission Fluid - Replacing the dirty transmission fluid, can help you to get rid of the P2729 error code. Do it as quickly as possible by shopping from PartsAvatar.
  5. Engine Wiring Connector - High temperature can cause corrosion of engine wiring connectors. Changing the damaged engine wiring connectors is essential so as to avoid the P2729 error in the vehicle.
  6. Filters - Visually inspect the filter for blockages or damages. If you find that there any blocks in the filters, replace or clean them clearly.
  7. Fuel Pump - More amount of moisture can cause the failure of the fuel pump. Replace or repair it as soon as possible.

Easy Diagnosis Of Engine Error OBD Code P2729

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

 

  • In order to start with, the mechanic will use a code reader or scanner along with DVOM to check for the P2729 error code.
  • Most of the vehicle which has been manufactured since the mid-80swith automatic transmission has a sophisticated computer-controlled system which accounts for several metrics of the drivability of the engine as well.
  • Once the error code is found in the vehicle, the mechanic will most likely check for the transmission pressure to see if it is sufficient enough for activating the gear changes.
  • If the pressure is found to be low, the transmission fluid will be checked to see if it is less or just murky.
  • If necessary, the dipstick will be checked then.
  • If everything is perfect including the fluid, the wires and the connectors have to be checked to make sure that the structural integrity is correct.
  • In a few cases, replacement of the entire internal transmission harness has to be done.

 

Common Mistakes When Diagnosing the P2729 Code

 

In most of the scenarios, the electronic pressure control solenoid and the malfunctioning of the wire is often mistaken to be faulty, and as a result the high-pressure pump is wrongly changed.
