Q: What does code P1180 mean?

Linear Oxygen Sensor Pump Current Short To B+. P1180 on Volkswagen vehicles means the engine control module has detected a short to battery positive voltage on the pump current circuit of a linear oxygen sensor, which is the wideband sensor used to measure air-fuel ratio. The sensor's internal pump cell is not receiving the expected current signal because the circuit is being pulled toward battery voltage, so the computer cannot trust the sensor's reading.
