Error Code P2729: What It Means & What To Do?
OBD Code P2729 - Pressure Control Solenoid "E" Control Circuit Low
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
- 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.
- Pressure Control
Solenoid - Replacing
the defective pressure control solenoid can help your system function normally.
- Transmission Control Module - Does the check engine light blink
very often? Then the TCM can be damaged which needs replacement to avoid P2729
error.
- 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.
- 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.
- Filters - Visually inspect the filter for blockages or damages. If you
find that there any blocks in the filters, replace or clean them clearly.
- 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.
