I checked under the hood for loose connections or broken wires and everything looked good. So I cleared the code and so far it hasn't come back. My question is where is this O2 Sensor because the Sensor 1 for Bank 1 or bank 2 are right on the exhaust manifolds next to the head, is Sensor 2 the one on the down pipe behind the turbo and Catalytic Converter? Is there only 3 O2 sensors on this car? ]]> Vettezilla https://acurazine.com/forums/6g-tlx-problems-fixes-470/p0140-o2-sensor-circuit-no-activitw-detected-bank-1-sensor-2-a-1012700/
