Code P0752 Mazda Description

The P0752 diagnostic trouble code (DTC) for Mazda vehicles indicates that the shift solenoid 'A' is stuck on. This means that the transmission control module (TCM) has detected a continuous signal from the shift solenoid 'A', which is responsible for controlling the flow of transmission fluid to engage the clutch packs that shift gears. When the shift solenoid 'A' is stuck on, it can lead to issues with gear shifting, causing the vehicle to experience problems with acceleration and overall performance.

Tech Notes for P0752 Mazda

When the a transmission solenoid is stuck on, in most cases the problem is not the electrical part of the solenoid; the problem is foreign material obstructing the mechanical function of the solenoid or the flow of the fluid through the transmission valve body. If the transmission fluid is very dirty, it is recommend changing the transmission fluid and if possible removing the transmission pan for further diagnosis. Excessive debris or metal particles on the transmission pan could be an indication that there is a transmission mechanical failure and that the transmission will need to be rebuilt or replaced.
