Pressure control solenoids are a critical transmission component, as they’re responsible for moving internal transmission components to initiate gear shifts. If problems with the pressure control solenoids occur, the P2723 code or other related trouble codes can be triggered. This article will help you learn about the P2723 code’s definition and common causes and symptoms.
What Does the P2723 Code Mean?
The P2723 code is defined as Pressure Control Solenoid “E” Performance/Stuck Off. The transmission has different pressure control solenoid groups that are labeled A, B, C, and so on. The powertrain control module (PCM) stores the P2723 code when the pressure control solenoid “E” is either stuck in the off position or not functioning properly.
Pressure control solenoids are responsible for controlling hydraulic fluid pressure within the transmission’s hydraulic circuits. This fluid pressure engages the appropriate clutches and bands at the appropriate time, which allows the transmission to shift gears. Given how important pressure control solenoids are to the transmission, the issues that trigger a P2723 code could result in various transmission-related symptoms.
Note: The definition of the P2723 code can be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.
What are the Common Causes of the P2723 Code?
The issues that trigger a P2723 code can be caused by the following problems:
- Faulty pressure control solenoid
- Dirty transmission fluid
- Clogged transmission fluid filter
- Faulty transmission pump
- Faulty transmission valve body
- Blockages in transmission fluid passages
- Internal transmission failure
- Faulty wiring
- Faulty PCM
What are the Common Symptoms of the P2723 Code?
Most of the symptoms of the P2723 code are transmission-related. These include the following:
- Illuminated check engine light
- Vehicle enables limp mode
- Increased fuel consumption
- Transmission not shifting properly
- Transmission overheats
How to Diagnose the P2723 Code
While the definition of the P2723 code indicates a problem with the pressure control solenoids, this isn’t always the case. You need to determine the main cause of this diagnostic trouble code (DTC) before you conduct any repairs. Otherwise, you might end up fixing a completely functional component.
You’ll need to thoroughly inspect other concerned components like the transmission filter and PCM to find the problem. This job might require the use of specialized tools and knowledge. If you find this task daunting, don’t hesitate to reach out to a professional mechanic.

How to Fix the P2723 Code
If you’re looking to fix the problems associated with the P2723 code, know that there isn’t a set procedure that will cure the issue. There are many ways to fix the underlying issues of OBD-II codes because they vary depending on the vehicle model, design, and layout. Sometimes, a trouble code can also trigger several related trouble codes. When this happens, you might need to fix the problems in the appropriate order as dictated by the manufacturer.
To learn about possible solutions, consult reputable internet repair resources and how-to guides. When you encounter DTCs, don’t forget to consult your vehicle’s repair manual.
It’s best to consult a professional mechanic if you don’t have much experience diagnosing or correcting error codes.
