How this error does get stored in the vehicle? What does P2723 error code mean? Improper shift transmission by pressure control solenoid "E" performance/stuck off gives rise to the P2723 error code. In order to apply the clutch packs, the TCM will use the pressure control solenoid so that it can control the hydraulic pressure in the transmission. The different gear ratios in the transmission will make your vehicle to propel proficiently on the right path. If the TCM finds that the pressure control solenoid is poorly performing, the P2723 code will be set.

This common type of trouble code applies to a vehicle which is well – fitted with automatic transmission. This error code is limited to vehicles like Nissan, Land Rover, Cadillac, Chevrolet, Chevy, Dodge, GMC, Mercedes Benz, VW, Audi, Pontiac, Saturn, Skoda, Honda, etc. The diagnostic steps will change based on the year, make and model of the vehicle. If the P2723 error is set, it actually means that the PCM has found error with the transmission pressure control solenoid "E". There are 3 solenoids A, B, and C in an automatic transmission. But there are 5 solenoids here – A, B, C, D, and E. the code is based on a specific error which signals the PCM and the check engine light keeps flashing. For the correct operation of automatic transmission, controlling the pressure of the fluid is the main purpose of the transmission pressure control solenoid. Based on the pressure within the solenoid, the PCM will receive an electric signal. Bands and clutches will control the automatic transmission which will change gear by fixing the fluid pressure at the right place and time. Depending on the signal received from the linked devices which monitors the speed of the vehicle, the pressure solenoid will be controlled by the PCM to direct the fluid at the correct pressure to several hydraulic circuits which alters the transmission gear ratio at the appropriate time.

What causes this problem with the Pressure Control Solenoid "E" Performance/Stuck Off?

• Damaged line pressure solenoid valve 'E'.
• There might be an opening or the line pressure solenoid valve 'E' harness might have a short circuit.
• The electrical connection of the line pressure solenoid valve 'E' circuit might be weak.
• Lacking fluid level.
• Murky or dirty fluid.
• Murky or clogged transmission filter.
• Broken transmission valve body.
• Constrained hydraulic passages.
• Internal errors in the transmission.
• Flawed pressure control solenoid.
• Transmission pump might be flawed.
• Corroded connector.
• Wires need repair.
• Broken PCM.

1. Powertrain Control Module - Overheating of the PCM can likely damage your PCM. Change it quickly by getting a new PCM from PartsAvatar.
2. Pressure Control Solenoid - A proper functioning of the pressure control solenoid is necessary to avoid P2723 error code.
3. Transmission Control Module - Delayed shifting is a sign of broken transmission control module. Replace it with a new one to avoid P2723 error.
4. Automatic Transmission Fluid - Fill the fluid up to the necessary level so that the system functions correctly.
5. Engine Wiring Connector - The engine wiring connectors play an important role in connecting various components. Is the engine wiring connector broken? Get the replacement for faulty engine wiring connectors at affordable prices from PartsAvatar.
6. Filters - Look if there are any blockages or muddy particles. Clear them to avoid system malfunction.
7. Fuel Pump - Does your engine surge very often? Then it is an indication that the fuel injector is faulty and it must be replaced quickly to avoid the P2723 error.

It is vital 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 P2723 here:

Common Symptoms

• Sliding of the transmission.
• Transmission may burn at times
• Reduced fuel economy.
• Possible indications of misfiring.
• Vehicle touches the limp mode.
• Well-lit check engine light.
• Fuel consumption is high.
• As you apply gear, the transmission might get stuck.
• Either the engine light or the warning light of the service engine will be on.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2723 code to be stored:

• Various tools can be helpful when you try to diagnose this error code.
• A reliable scanner, DVOM, an oscilloscope can prove to be highly helpful to carry out this diagnostic procedure.
• This error might be found if the transmission pressure is not sufficient and is mostly caused by a less or muddy transmission fluid condition.
• Start the diagnosis by looking at the transmission fluid dipstick.
• Visually examine the transmission level and make sure it is in good condition as specified by the manufacturer.
• The fluid that has either burnt or abnormal odor indicates that the transmission was operated when the fluid condition was low and there might be some mechanical failure.
• In such a scenario, the mechanic will drop the transmission pan to see if there are any rubble from the transmission.
• If there are any muddy particles, a total rebuild, fluid flush and replacement, and a new torque converter will be needed.
• Check the wires and connectors if there are no rubble.
• Fix the defective, detached or shorted wires, connectors, and other parts as necessary.
• If there are any discrepancies, the entire internal transmission harness has to be changed.
• If every system appears to be in proper working condition, attach a scanner to the diagnostic connector and recover every freeze frame data and stored codes.
• In order to diagnose the erratic condition, this information can be highly helpful as you can know how this error code was stored.
• This can help you to know if there is any erratic signal stored in the vehicle.
• Clear the error codes and check again if they appear so it can help to know if any malfunction occurred.
• If the code does not instantly return, it is because of an irregular condition.
• Try to worsen this situation before proceeding with further diagnosis as it is a risky task.
• If the fluid is in correct level, but low, then add more fuel and locate the leaky area.
• Allow the vehicle to arrive at the normal operating temperature by filling fluid and test drive to see if the error appears again.
• If the code does not show up, it might be because of transmission slippage or less fluid level/ pressure condition.
• But if the error shows up again, use a manual pressure gauge and check the pump pressure.
• Use a hydraulic pressure diagram and fix the end of the gauge into the correct opening on the transmission housing to calculate pump pressure.
• Check findings with the manufacturer’s specification.
• The main reasons for low pump pressure can be – the hydraulic passages that are blocked, the pump that is faulty, shift solenoids that are defective or may be an electronic pressure regulator which can be damaged.
• You must remove the transmission and partial assembly to replace the pump.
• If the transmission works fine and if the code returns quickly, inspect the reference voltage and ground signals at the electronic pressure control solenoid.
• Use a DVOM and check for continuity at the reference voltage or ground circuit if it is open.
• Repair every of the short, open or detached circuits as required.
• Test drive the vehicle by clearing the codes to make sure the diagnosis is successful.
• Test the circuits, electronic pressure control solenoid for resistance and continuity and make sure it matches the manufacturer’s specification.
• Replace or repair every component which fails to comply with the manufacturer’s specification.
• Test drive the vehicle by clearing the codes to make sure the diagnosis is successful.
• Manually operate the electronic pressure control solenoid to retest the system.
• If the control solenoid works perfectly, then the high-pressure pump, PCM, or torque converter can be faulty.
• Replacing the PCM requires programming.
• Replace the solenoid and recheck the TCM, if the electronic pressure control solenoid does not activate manually.

Common Mistakes When Diagnosing the P2723 Code

The damaged wires and the electronic pressure control solenoid is often overlooked as stated by the technicians and as a result, the high pressure pump is altered frequently.
