B0102Sensor Cleaning Air Blower Actuator A Control
- Generic OBD-II code · Body
- Can trigger limp mode
- How the car detects it
- B0102 narrows the blower A problem down to its control path: the controlling module sees a wrong voltage or current on the line that commands blower A, typically an open circuit, a short to ground or a short to supply. In Ford's lidar cleaning patent US10569746B2 a computer opens airflow from a blower or compressor by driving an electric solenoid valve and may modulate it; when window opacity exceeds about 30 %, air runs first and autonomous mode may be dropped. Ford's later patent US12115948B2 places the blower beside the sensor on its bracket, so its feed runs into an exposed pod. Valeo notes that an obstructed lens can end automated operation. No carmaker publishes B0102. Unlike B0100, the blower itself may be fine here.
