Q: What does code P1182 mean?

Linear Oxygen Sensor Reference Voltage Short To Ground. P1182 on Volkswagen vehicles indicates that the engine control module (ECM) has detected a short to ground on the reference voltage circuit of a linear oxygen sensor, which is the wideband air-fuel ratio sensor. The ECM monitors this dedicated reference line and sets the code when the voltage stays below the expected threshold, meaning the sensor cannot receive the stable reference signal it needs to report accurate exhaust oxygen content.
