Code P1852 Description

The diagnostic trouble code P1852 indicates that the Brake Band Apply Solenoid is experiencing low input voltage. The brake band apply solenoid is a critical component of the vehicle's transmission system that is responsible for applying the brake bands, which help control the shifting of gears within the transmission. When the input voltage to this solenoid drops below the specified range, it can lead to issues with the transmission's operation, potentially causing shifting problems, harsh gear engagement, or even transmission slippage.
