P2722 OBD Error Code: Problem & Solutions

<<See All OBD Codes

How do you know that the P2722 error code is stored in your vehicle? What are its symptoms and causes? The transmission which fails to shift correctly is known as pressure control solenoid "E". The pressure control solenoids are usually used by the transmission control module to control hydraulic pressure so that it supplies the different gear ratios for your vehicle to propel efficiently along the road as you apply the clutch pack. In case, the pressure control solenoid does not work properly, and if it found by the TCM, then the P2722 error code will be set.

Depending on the current flow, through its coil windings, the pressure control solenoid valve is an electronic pressure regulator which operates the transmission line pressure When the current flow is high, the magnetic field that is produced by the coil will move the solenoid’s plunger away from the exhaust port. The output fluid pressure will fall low when the exhaust port is wide open, which is controlled by the PC solenoid valve and it will decrease the line pressure. In order to meet the driving condition in response to a signal sent from the (TCM), the line pressure solenoid valve will operate the oil pump discharge pressure

What causes this problem with the Pressure Control Solenoid "E"?

• The line pressure solenoid valve 'E' might be damaged.
• You will see an opening or short circuit in line pressure solenoid valve 'E’ harness.
• Bad electrical connection in line pressure solenoid valve 'E'.
• The fluid is either muddy or dull.
• The transmission filter might be blocked.
• Crashed transmission valve body.
• The hydraulic passages may be restricted.
• Less fluid in the transmission.
• Your pressure control solenoid may be damaged.
• Corrosions in the connector.
• The wires may be faulty.
• Defective PCM.
• Damaged transmission pump.

1. Powertrain Control Module - The engine will fail to start or the fuel economy will be poor if the powertrain control module is faulty. Get them replaced as soon as possible so that you can get rid of the P2722 error code.
2. Pressure Control Solenoid - A faulty pressure control solenoid needs an immediate replacement for the system to function normally.
3. Transmission Control Module - Does the check engine light keep blinking? Then it’s a sign of a faulty transmission control system which needs immediate replacement.
4. Automatic Transmission Fluid - The automatic transmission fluid is used as a hydraulic fluid in some of the power steering vehicles. Replace the automatic transmission fluid at regular intervals so that the fluid remains clean and the engine functions normally.
5. Engine Wiring Connector - High temperature can cause corrosion of engine wiring connectors. Repair it as soon as possible.
6. Filters - The filter must be free from blockages and debris. Clean them to avoid P2722 error code getting stored by getting a new one from PartsAvatar.
7. Fuel Pump - Replacing your faulty fuel pump is always the best ideas as it will disturb the engine’s air-fuel ratio and cause performance related issues.

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 P2722 here:

Common Symptoms

• Transmission may slip while shifting.
• The transmission may overheat.
• Probable causes of a misfire.
• Vehicle drops to limp mode.
• Well-lit check engine light.
• Fuel consumption might be high.
• The transmission will refuse to shift properly.
• Possibilities for the transmission to get stuck in gear.
• Warning light of the service engine or the engine light will blink.

Here are some ways with the help of which you will be able to correct the OBD Code P2722:

• You have to change the fluid and filter.
• Defective pressure control solenoid needs reparation.
• The faulty transmission valve body should be replaced.
• The faulty transmission pump needs reparation.
• Flushing the transmission so as to clear blocks.
• Clearing the connectors which have rust.
• Changing the wires.
• Replacement of the PCM.

Here are some steps which you should follow in order to diagnose this P2722 fault code:

Fluid & Wiring Inspections

• Firstly check for the precise level of fluid in your vehicle and check their conditions. Also, double check your records as to when the filter and fluid of your vehicle were last altered.
• You may also have to visually examine the connectors and its associated connections for protection, erosion and damaged pins that might include the wires, connection to solenoids transmission, PCM and transmission pump.
• The transmission pump must be electrically or mechanically driven based on the configuration.

Advanced Steps

• The advanced procedure varies for every vehicle as they are specific and need proper diagnostic tools to carry out the diagnosis.
• Use a digital multimeter and appropriate technical references for your vehicle to start the process. Use your vehicle specific troubleshooting chart as it is always the best idea.
• Depending on your vehicle, the voltage requirements will change.
• Requirements for fluid pressure will also change based on transmission design and configuration.

Continuity Checks

• If it is not specified in the technical data, the normal readings of the connections for wires should be set to 0 ohms or as preferred by the manufacturer.
• Remove the power and check for continuity so there is no further damage and short circuit can be avoided.
• Suppose there is no resistance or continuity, then it clearly shows that the wires are defective or there is opening or shorted wire which needs to be fixed.

Common Mistakes When Diagnosing the P2722 Code

• Broken transmission control module.
• Less fluid in the transmission.
• Damaged transmission shift solenoid.
• Problematic wires.
• The engine might be misfiring.
• Faulty transmission pump.
• Issues in the internal transmission.
• Problems related to the driveline.
