P2724 - OBD Trouble Code

<<See All OBD Codes

What causes the P2724 error code to be stored in the vehicle? Am improper shift by the transmission is referred to as pressure control solenoid "E" stuck on. The pressure control solenoids are used by the TCM so that they can apply clutch packs in the transmission. The transmission will provide different gear ratio so that when the vehicle moves down the road, the vehicle will propel correctly. In case, the pressure control solenoid fails, and if it is found by the TCM, then the P2724 error will be set.

This common error code applies to vehicles which are equipped with automatic transmission and is not restricted to vehicles from Nissan, Land Rover, Cadillac, Chevrolet, Chevy, Dodge, GMC, Mercedes Benz, VW, Audi, Pontiac, Saturn, Skoda, Honda, etc. the diagnostic steps will change although its common based on the make, model, year and powertrain configuration. The PCM has found an issue with the transmission pressure control solenoid "E" when the P2724 error is set. Most automatic transmission which has only A, B, and C – 3 solenoids where here there are 5 solenoids – A, B, C, D and E. the error will be set based on a specific defect which signals the PCM and the CEL will be illuminated. The aim of the transmission pressure control solenoid is to look after the fluid pressure so that the automatic transmission works properly. Depending on pressure from the solenoid, an electronic signal will be received by PCM. With the help of bands and clutches, the automatic transmission is controlled and it can change gears by fixing the fluid pressure at the right place and time. By looking after the vehicle speed, based on the signal from linked devices, the PCM will control pressure solenoids to route the fluid at the correct pressure to several hydraulic circuits which alters the transmission gear ratio at the expected time.

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

• Broken line pressure solenoid valve 'E'.
• The harness of the line pressure solenoid valve 'E' might be shorted or it might have an opening.
• The electrical connection of the line pressure solenoid valve 'E' might be bad.
• The transmission fluid might be less.
• The transmission fluid might be murky.

1. Powertrain Control Module - If you find the check engine light on the display dashboard, then the PCM is faulty. Replace it as soon as possible to avoid the P2724 error.
2. Pressure Control Solenoid - Replace or repair the faulty pressure control solenoid so that you can avoid the P2724 error code getting stored in the vehicle.
3. Transmission Control Module - Poor fuel economy is an indication of bad TCM. Change it as soon as possible.
4. Automatic Transmission Fluid - Carefully inspect the transmission fluid if it is dirty or muddy. If so, replace them with clean fluid.
5. Engine Wiring Connector - A damaged engine wiring connector can cause an electrical problem in your car which will result in malfunctioning. Also, the fuel economy will get reduced as the flow of air will get blocked if the engine wiring connector is damaged. Fix it or replace it instantly.
6. Filters - Do you find any blocks or damages in filter? Remove them as soon as possible or get a new filter from PartsAvatar at the best prices online.
7. Fuel Pump - Insufficient voltage supply to the vehicle can cause the malfunctioning of the fuel pump. Avoid the P2724 error by fixing it quickly.

Willing to know some common symptoms of OBD Code P2724? Your wish is our demand. Have a look at them below:

Common Symptoms

• The vehicle arrives at the limp mode.
• While shifting, the transmission might slip.
• Heating of the transmission

We have listed out some ways which would help you to correct the occurrence of OBD Code P2724. They are mentioned here as follows:

• Alteration has to be done to the fluid and filter.
• Replacing the damaged pressure control solenoid.
• Fixing the faulty transmission valve body.
• Substituting the broken transmission pump.
• Clearing the transmission which has blockages.
• The connector must be dust free from erosion.
• Repairing the damaged cable wires.
• Replacement of the malfunctioning PCM.

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

• To correctly diagnose this error code, you will need various instruments.
• A DVOM, an oscilloscope, and a scanner can be highly helpful in performing a correct diagnosis.
• This type of code may be present if the transmission pressure is insufficient to actuate gear changes.
• Low or dirty transmission is the main reason of insufficient fluid pressure.
• Start the process by checking the transmission fluid dipstick.
• Make sure the fluid level sticks to the manufacturer recommendation and the condition is good.
• If the fluid smells like burnt, it means the transmission is functioning at the low-level condition and there may be internal failures.
• Take away the transmission pan and see for debris or rubble.
• If there are any muddy particles, a total rebuild, fluid flush and replacement, and a new torque converter will be needed.
• If you don’t find any contaminants check the internal wires and circuits.
• Carefully check the wires and connectors.
• The damaged wires, connectors, and other components have to be separated and repaired.
• The internal transmission harness must be fully changed if any discrepancy is found.
• After each successful diagnosis, recheck the system. Attach a scanner to the vehicle if every component is in proper working conditions and retrieve both the stored codes and freeze frame data.
• This is highly helpful to find if there are any irregular conditions which made this error code to get stored in the vehicle.
• Clear all codes and retest the vehicle to see if any error has occurred.
• This will help you to know if the condition was irregular. Clear all codes and retest the vehicle to see if an error appears again.
• The condition will be erratic if the code does not show up instantly.
• In one such situation, you have to worsen the condition of the vehicle before proceeding for further diagnosis as this is a challenging task.
• Add more fluid and check for the leaky area if the transmission fluid looks in decent shape.
• Allow the vehicle to reach the normal operating temperature by filling fluid and test driving the vehicle to see if the error shows up again.If the code does not show up, it might be because of transmission slipping 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.
• Repair accordingly by relating your findings with the manufacturer specification.
• The main reasons for low pump pressure can be – the hydraulic passages that are blocked, the pump that is defective, shift solenoids that are faulty or may be an electronic pressure regulator which can be damaged.
• You must take away the transmission and partial assembly to change the pump.
• If the transmission works fine and if the code returns instantly, visually check the reference voltage and ground signals at the electronic pressure control solenoid.
• With the help of DVOM check for continuity at the reference voltage or ground circuit if they are found to be open.
• Replace the shorted or open circuits as needed.
• Ensure a proper diagnosis is done by test driving the vehicle and clearing the error codes.
• Use the manufacturer's wiring diagram for the electronic pressure control solenoid and check for voltage and continuity and see if it agrees with the manufacturer’s specification
• Replace the shorted or open circuits which fail to obey the manufacturer’s specification.
• Ensure a proper diagnosis is done by test driving the vehicle and clearing the error codes.
• Attach a scanner to the diagnostic connector and activate the electronic pressure control solenoid manually.
• If everything works perfectly, then the high-pressure pump, torque converter, or PCM can be malfunctioning.
• Failure of PCM is rare and it needs reprogramming.
• You must change the solenoid and recheck the TCM if manual activation of the electronic pressure control solenoid does not take place.

Common Mistakes When Diagnosing the P2724 Code 

Some of the technicians always report that the damaged wires and electronic pressure control solenoid is always mistaken and due to this fault, the high-pressure pump is changed.
