P2274 in the Opel Astra is a general diagnostic trouble code. It means that the “bank 1” oxygen sensor (third oxygen sensor from the exhaust manifold, behind a catalytic converter) is continuously sending voltage that indicates a lean air/fuel mixture. This does not necessarily mean that the vehicle is running lean (although it can, … Read more
