P0752 Code: Shift Solenoid “A” Stuck On

The OBD-II system helps drivers know about the potential issues in their vehicles. To view these trouble codes, you’ll need to plug a scan tool into your vehicle’s OBD-II port. The P0752 code is one of the many codes you might encounter. Find out what it means, as well as its possible symptoms and triggers here.

What Does the P0752 Code Mean?

Diagnostic trouble code (DTC) P0752 stands for “Shift Solenoid “A” Stuck On.” This code sets when the transmission control module (TCM) detects that a shift solenoid is not functioning as expected. Automatic transmissions typically have three solenoids referred to as A, B, and C. The “A” in this code’s definition refers to the transmission shift solenoid designated “A.”

The TCM or the powertrain control module (PCM) manages the movement of fluid and the transmission fluid pressure to change the transmission’s gear ratio using the shift solenoid circuit. If the PCM or the TCM detects that the shift solenoid “A” isn’t operating properly or if it’s stuck in the “On” position, it will set the P0752 code.

If this code is set, you need to take your vehicle to a shop for diagnosis and repairs as soon as possible. If left unaddressed, the P0752 code can cause more severe issues down the line. Driving with this code is not advised.

If your vehicle is equipped with a transmission warning lamp, it might also illuminate if the P0752 code sets. Other DTCs related to the P0752 include P050, P0751, P0753, and P0754. These codes are also associated with the A, B, or C solenoid circuit.

Note: The definition of code P0752 might 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 P0752 Code?

Many trouble codes have multiple possible causes and the P0752 is no exception. Some of the most common causes of the P0752 code include the following:

• TCM failure
• Low transmission fluid level
• Transmission shift solenoid malfunction
• Wiring issue
• Clogged or restricted transmission filter
• Defective transmission valve body
• Internal failure in transmission
• Corroded or damaged connector

What are the Common Symptoms of the P0752 Code?

While some DTCs can show signs, others don’t. Here are some of the most common symptoms you might encounter when dealing with the P0752 code:

• Illuminated malfunction indicator lamp or check engine light
• Transmission might not shift properly
• Transmission overheating
• Transmission catches in gear
• Increased fuel consumption
• Vehicle might enter limp mode

How to Diagnose the P0752 Code

Different DTCs can have similar causes, symptoms, and areas of concern and this can lead to confusion. Before you can even fix a trouble code, you’ll need to identify the root cause first, and this requires thorough troubleshooting and diagnosis. But not everyone is familiar with DTC troubleshooting and repair, so it’s best to consult a certified mechanic first.

Fortunately, there are plenty of auto repair resources available today. Of all these sources, vehicle-specific repair manuals and guides are your best choice because they have detailed information and have helpful diagrams and illustrations as well.

Learning more about a trouble code can help you understand its causes and how to prevent issues down the line. If you want to know more about the diagnostic and repair procedures for the P0752 code, here are some videos that explain these processes in more detail:

How to Fix the P0752 Code

A single DTC can have multiple possible causes and each of these causes have their own set of possible solutions. Possible solutions to trouble codes will vary depending on the vehicle manufacturer, making diagnosis and repair even more complicated. There’s no single cure-all fix for trouble codes. A solution that fixed the P0752 in a GMC Acadia might not be able to repair the P0752 in an Acura TL.

Proper diagnosis is key to repairing a DTC. However, not everyone has access to the tools and expertise needed to fix trouble codes like the P0752. If you’re not familiar with DTC repairs and troubleshooting, it’s best to have a certified mechanic do the job for you so you can avoid even more complicated problems later on.
