C2801 Brake Pressure Transducer Sense Short to Ground 2

OBD2 Code: C2801

Description: Brake pressure transducer sense short to ground.

Definition: This code indicates a problem with the brake pressure transducer circuit, specifically a short to ground condition. The brake pressure transducer is responsible for monitoring the hydraulic pressure in the braking system and providing this information to the vehicle’s control module. A short to ground means that there is an unintended electrical connection between the sensor signal wire and the vehicle’s chassis or negative battery terminal, which can lead to incorrect readings or failure of the braking system components.
