What does the engine code P2723 mean?
Definition: Pressure control solenoid ‘E’ performance/stuck off
The P2723 engine code indicates that the pressure control solenoid in the transmission has a problem with its electrical circuit.
The pressure control solenoid regulates the flow of fluid in the transmission, which is made up of friction clutches and bands. A faulty pressure control solenoid can cause these internal clutches and drum bands to seize up or slip, which can result in the transmission overheating.
How much will it cost to fix?
The average cost to fix your pressure control solenoid is between $75 to $150 per hour of labor.
Keep in mind that the cost of this service varies depending on certain factors, including:
What can cause the P2723 engine code?

- A faulty transmission, control solenoid, or ECM module
Common symptoms of the P2723 engine code
The symptoms of the P2723 can vary in severity. At worst, your car may be unable to shift gears. Less severe symptoms include:
- Weaker fuel efficiency
- Problems with car’s handling (i.e. vibrating, slipping, revving too high)
How serious is the P2723 engine code?
In the most extreme case, the P2723 engine code can be very serious—as it affects your car’s driveability. It’s best to have it repaired immediately.
Can I fix the P2723 engine code myself?
While it may be possible to fix the P2723 engine code yourself, a correct diagnosis of a transmission problem is best accomplished with a professional transmission scan. This is typically performed at a transmission shop or car dealership. If you do decide to fix the P2723 engine code yourself, you’ll have to inspect the transmission to determine what part of the solenoid circuit is faulty. To accurately diagnose the problem, follow these steps:
- Look at the levels and condition of the transmission fluid—if the fluid is dirty or there are metal shavings present, the transmission could have serious internal damage.
- If the transmission fluid is clean and the levels are good—the wiring harness and connectors should be inspected for damage.
- If no damage is found to the harness or connectors—test the pressure control solenoid according to your car manufacturer’s instructions.
- If the solenoid functions properly—the ECU, valve body or transmission pump could be faulty.
