Too much oxygen (the engine is running lean), it tells the computer There is a disconnect here, VW Parts listings calls out the O2 sensors as Rear Oxygen Sensor, RIGHT or Rear Oxygen Sensor, LEFT and if you useVCDS to read your MIL you get the bad O2 sensor called out as Bank 2, Sensor 2 2947 - Oxygen (Lambda) Sensor Signal B2 S2 P2272 00 [096 . These sensors are mechanically connected to a float which moves up or down depending on the fuel level. When a car calls for left or right they are always referring to the car as if you are sitting in the seat looking forward. The result is that the fuel gauge will not read accurately. For example, there are two possible definitions of code P0460 on a 2018 Ford F-350 Super Duty King Ranch. Damage to the fuel tank could cause problem in fuel level circuit. The powertrain control module (PCM) stores the trouble code P0462 when it detects a possible issue with the fuel level sensor circuit.
