I just replaced o2 sensor in the front and now the engine

Customer Question

hi, i just replaced o2 sensor in the front and now the engine light came on with code p0172, rich in bank 1. I think it may be the fuel pressure regulator needed to be replaced, but i am not sure where the fuel pressure regulator located on my 2002 town and country. thanks
JA: Have you located all of the vehicle's oxygen sensors? Are the wires leading to and from each intact and in good shape?
Customer: yes, I have located 1 sensor in the front and another one on the back of it (downstream).
JA: What is the model of your '02 Dodge?
Customer: sorry, it's a town and country 3.3L.
JA: Are you fixing your Town and Country yourself? What have you tried so far?
Customer: yes, I did. I've changed all 6 fuel injectors, replaced all park plugs, spark plug wire, and the rotor caps(?)
JA: Anything else you want the mechanic to know before I connect you?
Customer: i am trying to clear code p0172 actually. thanks

Did you only get the code after replacing the O2 sensor? Does the code go away if you install the original O2 sensor? Was the O2 sensor OEM or one from Napa?
