Code P1853 Pontiac Description

The P1853 diagnostic trouble code (DTC) for Pontiac vehicles indicates a high input voltage in the Brake Band Apply Solenoid circuit. The Brake Band Apply Solenoid is responsible for controlling the application of the brake band in the transmission. When this solenoid receives a high input voltage signal, it means that there is an issue with the electrical circuit that controls the solenoid. This can lead to improper engagement or disengagement of the brake band, affecting the vehicle's transmission operation.
