The P2723 code definition is “Pressure Control Solenoid E Performance/Stuck Off,” and in some cases, “performance” is shortened to “perf.” This code indicates that your vehicle’s powertrain control module (PCM) or engine control module (ECM) has detected that pressure control solenoid “E” is either stuck in the “Off” position or is in some way not functioning properly. As a generic powertrain code, you could find the P2723 OBD-II trouble code in a variety of modern vehicles with an automatic transmission.
More About the P2723 Code
Automatic transmissions rely on pressure solenoids to control hydraulic fuel pressure within your vehicle’s transmission hydraulic circuits. By engaging specific clutches and bands at the right time, the transmission shifts gears as necessary. Depending on how many gears your vehicle has, there will be a number of different solenoids, usually identified with capital letters, like A, B, and C. This control solenoid trouble code indicates that the E solenoid, which may be associated with a higher gear, has malfunctioned in some way.

What Are the Symptoms of a P2723 Code?
The first common symptom that most people experience with this diagnostic trouble code is that the check engine light will turn on; as a CEL code, it could also turn on other malfunction indicator lamps, such as your transmission warning light. However, because this is a transmission gear ratio concern, you could end up with a wide variety of other symptoms as well, depending on the actual concern underlying the code. This may include general issues with transmission shifting and transmission overheating, as well as increased fuel consumption. In more severe cases, your vehicle may enter Limp Mode or Limp Home Mode, which could cap vehicle speed and disable certain vehicle functions, such as the air conditioning system.
What Are Some Causes of a P2723 Code?
This is an incredibly broad and generally quite vague fault code, which means there are many, many possible causes. Here are just a few of them:
- Faulty pressure control solenoid
- Dirty transmission fluid
- Low transmission fluid level
- Clogged transmission fluid filter
- Faulty transmission pump
- Faulty transmission valve body
- Blocked hydraulic passages
- Damaged electronic pressure regulator
- General internal transmission failure
- Overall, faulty wiring and electrical connections
- Faulty PCM or PCM programming error
You’ll need to check out not only this transmission code but also any other engine codes your vehicle is throwing to determine the underlying cause. For example, if the problem is low fluid pressure or hydraulic pressure, there may be a leak in your transmission hydraulic passages.
How Serious Is the P2723 Code?
OBD code P2723 should be considered quite serious, the same way any error code related to your transmission should be considered. Concerns with transmission line pressure can lead to overall issues related to your transmission; if there’s a problem with corrosion from connectors in your wiring harness, for example, your vehicle may not be able to shift into the gear related to transmission pressure control solenoid “E,” which can cause overheating and lower than ideal fuel economy. It’s a very serious code that you should fix as soon as possible.
Can I Still Drive with a P2723 Code?
You may or may not be able to physically drive with this pressure solenoid valve code. If your vehicle applies Limp Mode or Limp Home Mode, for example, you might be able to drive, but only in a way that can be very frustrating to do for long periods of time. Regardless of whether you can physically drive, however, it’s not a good idea. If there’s a serious problem within your transmission causing this problem, like a defective transmission valve body, driving the vehicle may result in metal shavings from the transmission going into the transmission fluid, which can raise incredibly serious problems throughout the vehicle and result in a more expensive and complex fix later. Repair defective components early to avoid more expensive problems later.
How Easy Is It to Diagnose a P2723 Code?
It can be quite difficult to diagnose the P2723 code. You’ll need to check a number of issues here — the electrical circuits within your vehicle, your wiring harness connector pins, and possibly even your powertrain control module or transmission control modules. Plus, you’ll probably need to look for other codes and determine which one to inspect first, as many codes can arise from other problems that show up as OBD-II codes. In general, this diagnostic process is complex, and it’s best to get help with it if possible.
How Difficult Is It to Inspect a P2723 Code?
Inspecting the P2723 code can be extremely difficult as well. Most DIYers don’t have the same experience that auto repair shops do, which means you probably don’t know how all of these components look when they’re functioning properly. Plus, you may not know how to service engine problems residing within the transmission area effectively. Inspecting the P2723 code is difficult for many DIYers, which is why it’s a good idea to talk to an expert instead.
