P2720 - OBD Trouble Code

<<See All OBD Codes

Is your pressure shift solenoid valve ‘D’ broken? Is the transmission fluid dirty? Then there is a chance that the P2720 error is stored in the vehicle. Improper transmission shift is known as pressure control solenoid "D" control circuit low. The hydraulic pressure in the transmission is handled by the TCM which uses the pressure control solenoid. This is especially used to apply clutch packs in the transmission so that when the vehicle applies different gear ratios, it will proficiently propel down the road in the right direction. If suppose, the solenoid does not function as expected, then the P2720 error code will be stored which is detected by the TCM.

The pressure control solenoid valve is an electronic pressure regulator which operates the transmission line pressure depending on the current flow, through its coil windings. When the current flow increases, the magnetic field produced by the coil will move the solenoid’s plunger far away from the exhaust port. The output fluid pressure will get decreased when the exhaust port is opened, which is regulated by the PC solenoid valve and it reduces the line pressure. The line pressure solenoid valve will operate the oil pump discharge pressure to meet the driving condition in response to a signal sent from the (TCM).

What causes this problem with the Pressure Control Solenoid D Control Circuit Low?

• Defective line pressure solenoid valve 'D'.
• Line pressure solenoid valve 'D' harness might have an opening or short circuit.
• Line pressure solenoid valve 'D' circuit might have a weak electrical connection.
• Deficient fluid level.
• Muddy or polluted transmission fluid.
• Muddy or blocked transmission filter.
• Faulty transmission valve body.
• Limited hydraulic passages.
• Internal faults in the transmission.
• Defective pressure control solenoid.
• Rusted or injured connector.
• Defective wiring.
• Broken PCM.
• Transmission pump failure.

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 P2720 error code
2. Transmission Control Module - Flashing of the check engine light is an indication of a defective transmission control system. Fix it as soon as possible.
3. Automatic Transmission Fluid - The automatic transmission fluid can get contaminated easily and so they must be drained out at regular intervals. P2720 error can be avoided if the dirty or murky automatic transmission fluid is quickly replaced.
4. Engine Wiring Connector - If the engine wiring connectors are overheated, it will quickly result in corrosion. Get the replacement for your damaged engine wiring connectors from PartsAvatar.
5. Filters - Your vehicle might malfunction if there are any muddy particles or blockages in the filters. Alter it as soon as possible.
6. Fuel Pump - The overall performance of the engine will be poor if the fuel pump is defective. Change it as soon as possible.
7. Electronic Pressure Regulator - Emission of black smoke from the exhaust is a sign of a faulty electronic pressure regulator. Replace it quickly to avoid P2720 error.
8. High Pressure Pump - There will be a loss in oil pressure if the high-pressure oil pump is defective. Change it quickly to avoid the P2720 error code.
9. Transmission Valve Body - Get the right replacement for your faulty transmission valve body from PartsAvatar at the best prices online.
10. Transmission Shift Solenoid - Are you looking for the right replacement for your faulty transmission shift solenoid? Grab them from PartsAvatar to avoid P2720 error.

Next important thing you need to know about are the common symptoms for this OBD error code P2720 with your fuel volume control.

Common Symptoms

• Transmission gliding.
• Burning of the transmission.
• High fuel consumption.
• Possible symptoms of a misfire.
• Vehicle reaches limp mode.
• Check Engine Light well-lit.
• Slippage of the transmission.
• Very hard shift by a transmission which keeps banging into the gear.
• Flashing of the engine light or service engine soon warning light.

Wish to correct this error code with your vehicle? Do you know what all you should do to make your car free from this code P2720? Well, don’t worry! We are here to guide you.

• Replacement of fluid and filter.
• Correcting the faulty pressure control solenoid.
• Repairing the defective transmission valve body.
• Repairing the defective transmission.
• Flushing the transmission to clean passages.
• Dusting erosion from connectors.
• Repairing the wires.
• Replacement of PCM.
• Fixing the faulty transmission pump.

Apart from the fuel injector, you might need to undergo a few more replacements. You might need transmission, PCM, pressure control solenoid, transmission fluid, transmission control module, electronic pressure control solenoid, pressure gauge, connector, shift solenoids, electronic pressure regulator, torque converter, high pressure pump, transmission filter, transmission valve body, transmission pump, transmission shift solenoid, driveline and many other parts. Where to get them from? Well, if you want quality parts, then we can prove to be your dream destination.

If you want to easily diagnose this fault code P2720, then all you have to do is to follow the steps which are mentioned below:

Fluid & Wiring Inspections:

Initially check for the right level of fluid and inspect them for its condition. You can also check for records of the vehicle to see when the filter and fluid were last changed. Secondly, you have to inspect the connectors and its connections for safety, erosion and broken pins including transmission pressure control solenoids, the transmission pump, and the PCM. The transmission pump must be electrically or mechanically driven based on the configuration

Advanced Steps:

The advanced step for each vehicle varies and needs the proper tools to perform correctly. The process needs a digital multimeter and particular technical references for your vehicle. Before you proceed with the advanced steps, you must always gather the particular troubleshooting data for your vehicle, Requirement of voltage will vary based on specific models of your vehicle. Need for fluid pressure will change based on the transmission design and configuration.

Continuity Checks:

The readings should be set to 0 ohms or as specified by the technical data. You have to check for continuity by removing power so that further damage and a short circuit is avoided. If there is no resistance or continuity, then it indicates that the wires are faulty or there is an open or shorted wire which needs replacement.

Common Mistakes When Diagnosing the P2720 Code

• Faulty TCM.
• Level of fluid in the transmission is low.
• Defective transmission shift solenoid.
• Electrical wires have issues.
