I am looking for sensor 1 in bank 1 on a 2001 dodge caravan with a 3.3 ,can you help?

 

I think both sensors are on the exhaust manifolds. Do you know what they look like? The are about the size of a spark plug. If I remember right (I replaced one on my 2000 Caravan, the back is a bear to get to the front is nice and easy - front and center.

 

Bank 1 Sensor 1 is on the rear exhaust manifold. It is a heck of a lot easier to change on an 01 than a 00. Bank 1 Sensor 2 is after the converter. There isn't an oxygen sensor in the front exhaust manifold
