The OBD-II diagnostic code P2716 is defined as “Pressure Control Solenoid ‘D’ Electrical.” Suppose either your powertrain control module (PCM) or your transmission control module (TCM) have identified a problem with your pressure control solenoid or its attached circuit. In that case, you may see this diagnostic trouble code pop up. This code specifically refers to the “D” circuit; if there are multiple pressure control solenoids, they’re named “A,” “B,” “C,” and so forth. As a generic powertrain code, you may see this error code in a variety of OBD-II equipped vehicles with automatic transmissions.
More About the P2716 Code
Your automatic transmission functions primarily through the usage of hydraulic fluid pressure inside the transmission. Hydraulic fluid pressure is applied to specific hydraulic circuits, causing the transmission to shift gears to serve your vehicle’s needs more accurately. Solenoids are an important part of regulating the fluid pressure within the hydraulic circuits. If you’re seeing the P2716 code, it means that your PCM or TCM has identified a problem with your pressure control solenoid, which can have repercussions throughout your automatic transmission.

What Are the Symptoms of a P2716 Code?
As with most vehicle error codes, the most common symptom is an illuminated check engine light. However, this code also frequently comes with drivability problems, as this code can indicate that there’s a problem surrounding the solenoid that helps your vehicle handle hydraulic pressure related to transmission gear switching. You may see a higher fuel consumption overall, and your vehicle may have difficulty switching gears. In some cases, the vehicle may even enable “Limp Mode” or “Limp Home Mode,” which can shut off certain processes like your air conditioning and reduce your vehicle speed.
What Are Some Causes of a P2716 Code?
There are many possible causes of the P2716 code; this code doesn’t indicate anything about the core problem, just the symptom that the problem in question is causing. While definitely not a complete list, here are a few of the causes you might want to be looking for:
- Dirty transmission fluid or low fluid level
- Defective transmission valve body
- Faulty transmission pump
- Faulty pressure control solenoid
- Clogged transmission filter
- Valve body issue
- General electrical problems, such as frayed wiring
- Internal transmission failure
- Faulty PCM, although this is rare
How Serious Is the P2716 Code?
Code P2716 should definitely be seen as quite serious. This kind of electrical connection is key to one of the most fundamental components of your vehicle. Smooth transmission operation allows your vehicle to function overall, and DTC P2716 can have significant repercussions throughout the entirety of the vehicle. When you see this transmission code, it’s a good idea to take it seriously. This is even true if you don’t see drivability problems immediately—the last thing you want is to ignore this problem until it develops into an issue that leaves you stranded.
Can I Still Drive with a P2716 Code?
Physically, most people can continue driving the vehicle with the P2716 code active. Your engine outputs may be less effective, with common problems including a lowered fuel economy and general difficulty in driving the vehicle. However, even though many people can physically drive their car with this transmission code active, it’s generally not recommended. The code can cause problems over time, and it’s more likely that you’ll have serious transmission problems if you continue to drive when this code is active.
How Easy Is It to Diagnose a P2716 Code?
Diagnosing the P2716 code is extremely difficult in many cases because it’s not necessarily easy to determine the core cause. As you’ve already seen, there are as many as a dozen or more potential causes that you need to understand before you start looking into the code. Regardless of the problem, you’ll need to follow diagnostic procedures to ensure a quality fix that isn’t just a band-aid coverup. An expert will be able to determine the core problem and help you fix it without needing a follow-up repair in the future.
How Difficult Is It to Inspect a P2716 Code?
As with diagnosis, inspection is also frequently very difficult for the P2716 code. Not only do you need to use a variety of potentially advanced tools, but you’re also dealing with the transmission, which tends to be a very finicky and extremely critical part of the engine. If you make a single mistake, you could end up having to spend much more on a follow-up repair. This is just one of the reasons that most people don’t recommend you inspect this code on your own and instead that you contact an expert.
Need Additional Help with Your P2716 Code?
Don’t worry if you feel like you need additional help with your P2716 code. This code is a difficult one for most DIYers to fix, so it’s important that you get the help necessary.
Your first step should be to find an auto repair shop in your area. A local auto repair shop is a great starting point for people who want help with their vehicle problems that don’t feel like issues you can just DIY. Plus, if you’re having drivability concerns, a local shop will allow you to fix them without having to go too far out of your way.
The OBD-II database is another great tool if you’re planning to take your car to an expert. This way, you’ll be able to see what problems are turning up on your scan tool, allowing you to learn more about what issues you might end up seeing.
