P3025 MINI Code - Upstream Oxygen Sensor Signal Controller Monitoring Initialization Error Bank 2 Sensor 1
Quick Answer
This function will detect an error during the initialization and/or operation of a WRAF sensor controller through SPI communication. Common causes include Faulty Upstream Oxygen Sensor Bank 2 Sensor 1, Upstream Oxygen Sensor Bank 2 Sensor 1 harness is open or shorted, Upstream Oxygen Sensor Bank 2 Sensor 1 circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P3025 MINI Description
After an ECU reset, the WRAF sensor controller is started and the diagnosis determines whether the initialization has been performed in the allowed time. If not successful, then a DTC will be stored. If this is successful, then the difference is checked between the present error counter and the stored value of this error counter at ECU reset, (switching from Key
