The definition of code P0752 is “Shift Solenoid A Stuck On.” This is an incredibly generic trouble code that simply indicates your vehicle’s powertrain control module (PCM) or engine control module (ECM) has detected a problem in function with shift solenoid “A.” Despite the title saying “Stuck on,” this is quite a generic code, and it only indicates an abnormality in shift solenoid “A.” As a generic powertrain code, you may see the P0752 code in any OBD-II vehicle with an automatic transmission.

More About Error Code P0752
Your vehicle’s solenoids allow it to shift from one gear to another. When driving an automatic transmission, the gears are selected with no input from the driver. The solenoids allow your vehicle to shift into whatever gear will deliver the optimum power for your vehicle’s speed. This code means that the vehicle has detected that the ECM has selected a specific gear, but the expected change didn’t actually occur. For example, your vehicle may have chosen third gear, but other sensors within the vehicle are indicating that you’re actually in second gear.

What Are the Symptoms of a P0752 Code?
Transmission-related issues are very common with the P0752 OBD-II trouble code, and you can experience all sorts of drivability concerns regarding this fault code. You can expect harsh shifting, transmission slippage, and transmission overheating. Sometimes, the transmission won’t shift, so you can’t drive your vehicle, as it’ll be stuck in first gear. Even if you can technically drive the vehicle, it’s common to see it activate “Limp Mode” or “Limp Home Mode,” which limits vehicle speed and shuts off unnecessary systems. You should also see the check engine light turn on.
What Are Some Causes of a P0752 Code?
Sometimes, the problem causing the P0752 diagnostic trouble code is that your transmission filter is clogged or broken, or you’re dealing with dirty or low transmission fluid. If there is an actual physical problem, it’s common for it to be a faulty shift solenoid, faulty wiring and electrical connectors, or problems in other areas of the transmission, such as the transmission pump or valve body. It could be a problem with PCM failure in some rare cases, but this is exceptionally uncommon.
How Serious Is the P0752 Code?
Any transmission code should be treated as exceptionally serious. Even if you’re not currently experiencing drivability issues, which you likely will be, refusing to deal with this code quickly will result in engine damage. Transmission-related codes are dangerous and likely to result in more significant engine damage. Replacing your transmission is a difficult and expensive repair. Fix the problem early on to avoid higher repair costs.
Can I Still Drive with a P0752 Code?
You definitely should not drive with a P0752 code active. In some cases, this code can make it impossible for you to switch gears at all, which can result in severe issues with drivability. However, even more importantly, the more you drive when a transmission code is active, the more likely you will damage your transmission. On top of potential safety issues, the likelihood of damaging your transmission makes it a good idea to avoid driving with this code active.
How Easy Is It to Diagnose a P0752 Code?
If the problem only has to do with your transmission filter or transmission fluid, you may be able to diagnose the problem easily by adding fresh fluid and ensuring the movement of fluid is restored. However, you may need more knowledge and information to diagnose issues with a shift solenoid, faulty wiring, or other components within the transmission. If you don’t know how to diagnose issues within your transmission, it’s best to leave this process up to a certified mechanic, as it can cause severe issues if you make any common mistakes.
How Difficult Is It to Inspect a P0752 Code?
As with diagnosis, the inspection process for your P0752 code can be very difficult. Not only do you need to be able to perform a visual inspection, looking for signs of damage and corrosion, but you’ll also often need advanced tools. For example, on top of a code scanner, you may need a digital volt/ohmmeter (DVOM) and a source of reliable vehicle information, like technical service bulletins and vehicle repair guides. It’s best to leave this code inspection to the experts to avoid needing a follow-up repair.
Need Additional Help with Your P0752 Code?
You’re not alone if you need extra help with your P0752 code. Plenty of people end up needing help, and that’s why a professional mechanic can be so helpful here.
Start by finding an auto repair shop in your area. A local automobile repair shop will give you the care and repairs you need without being too inconvenient.
