The car is giving me code P0154 (no activity on o2 sensor bank 2 sensor 1). I already ordered the replacement o2 sensor just having trouble finding exactly where to find where this sensor is located. Is it underneath the car or can it be accessed through the hood? Thank you

Yep, the primary oxygen sensor is up near the engine's exhaust manifolds while the secondary sensor is down on the exhaust system after the catalytic converter. Here is a generic guide to help you step by step with instructions in the diagrams below to show you how on your car.

You can change it from under the hood. Bank 2 sensor 1 is near the cylinder head in the exhaust manifold on the left side of the engine closet to the radiator.
