Where is Bank 2, Sensor 1, on a 2010 Chrysler Town and Country Limited 4.0L

It's the upstream oxygen sensor that is on the side of the engine of the number two cylinder. It's usually on the exhaust manifold. But it's definitely before the catalytic converter. Hope that helps! Jim

Thank you Jim. You just raised my guess from 80%, to 98.5% that this will solve my problems of fuel consumption, and the reason I didn't say 100%, is because I'm just going by a check engine light, OBD code, P0153. I'm sure that, that can indicate an Upstream Sensor, but I'm not sure how I determined a Bank 2 sensor. But I'm just gonna go for it, and replace it. Thank you again for your response. Frank
