Check engine light giving me codes PO141 AND p0135

I replaced both. I have two codes present as posted. Is this all related to the Bank 1 sensor?

no one code is b1 sensor #2 and the other is b1 sensor #1 you have 2 seperate sensor codes.b1s2 code is a malfunction code and po135 is the heater circuit on b1 sensor 1. look at the wiring on b1s2 sensor and the heater part may be burned out on b1s1

b1s2 was the original problem. It was initially struck underneath by the drive axle. It has been replaced with a factory part. I decided to be vigilant and replace b1s1 with a new part. Now I know the meaning of if its not broke don't fix it. Car has around 115,000 miles. What about a vacuum leak??
