Its not ur O2 sensor then. There is something wrong before the 02 thats making it read wrong. What was that the only code that was present?

Which sensor on bank 1 did you replace? Maybe you replaced the wrong one?

bank 1 sensor 1: in header (pre-cat)

Bank 1 sensor 2: in cat (post-cat)

this engine only has one bank, as do all inline engines.

A V-engine has 2 banks.

Some Sentras have epically confusing B1/B2 02 sensors on a inline 4cyl.
