Code P1179 Audi Description

The P1179 Audi code indicates a problem with the linear oxygen sensor pump current being shorted to ground. The oxygen sensor, also known as the O2 sensor, is responsible for monitoring the oxygen levels in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. When the sensor pump current is shorted to ground, it means that the signal being sent by the sensor is not reaching the ECM properly, which can lead to incorrect fuel trim adjustments and potentially affect the vehicle's performance.
