P0752 OBD-II Trouble Code: Shift Solenoid A Stuck On

check engine light

P0752 code definition

The P0752 code signals that an abnormality was detected by the PCM in shift solenoid A.

What the P0752 code means

If this code gets stored by your PCM, it’s because the vehicle isn’t shifting correctly. Your computer-controlled automatic transmission works by using shift solenoids to manage the fluid running between the hydraulic circuits. By doing so, they can actuate a change in the transmission ratio gear.

Varying gear ratios are necessary to speed up or slow down, get the best possible fuel efficiency and maximize the performance of your engine.

When the P0752 code is triggered, it’s because the gear required by your vehicle’s ECM doesn’t line up with the actual gear when you’re driving.

What causes the P0752 code?

This code can be stored for a handful of reasons:

What are the symptoms of the P0752 code?

There are really only two symptoms that will occur in relation to a P0752 code. The first is that the Check Engine Light should come on. The second is that your vehicle’s transmission will refuse to shift gears.

How does a mechanic diagnose the P0752 code?

Your mechanic will use a scanner and a digital ohmmeter to diagnose this code. If they find that multiple shift solenoid codes have been stored, this will tell them that delayed engagement or transmission component slippage has occurred.

Next, they’ll check to see if the transmission pressure is sufficient for actuating gear changes. They’ll also check to see if transmission fluid pressure is low and/or has burned.

Your mechanic will inspect the system’s wiring and connectors to see if they’re in normal working order.

Finally, they’ll connect the scanner to the diagnostic connector and record all the trouble codes that have been stored and freeze frame data as this information can be helpful for identifying any intermittent conditions that may have led to the code being stored.

Common mistakes when diagnosing the P0752 code

As we mentioned above, this code may be triggered because of a malfunctioning shift solenoid circuit. In fact, that’s one of the most common reasons this code appears. However, despite how prevalent this problem is, it often gets missed.

Instead, shift solenoid malfunctions are blamed and a replacement is carried out in error.

How serious is the P0752 code?

The code isn’t serious insofar as it won’t put your life in danger. However, it will make your vehicle impossible to drive because you can’t shift gears. If you try forcing the vehicle into gear, you could also wind up doing a lot more damage.

What repairs can fix the P0752 code?

Fortunately, repairing the problem that is triggering this code could be relatively simple and quick:

Additional comments for consideration regarding the P0752 code

When the transmission solenoid is stuck, most of the time, the problem isn’t going to be the electrical part of the solenoid. Instead, the problem is going to be a foreign material getting in the way of the solenoid’s mechanical function or the flow of fluid through the transmission valve body.
