02 ford explorer
hey guys i pulled these codes last night at orielys off my 02 ford explorer, p0174 & p1151. my logic would be that since its only talking about bank 2 seansing lean and the bank 2 sensor isnt switching reasonably just replace the b2s1 ho2 sensor. does that fit with everyones thought process?
:shoot:

also orileys has upstream and downstream o2 sensors. because (according to all diagrams the bank 2 sensor21 is located just in the exhaust manifold, before the cat,) would you call this the upstream sensor?
 






Before replacing an oxygen sensor, switch it with the one on the opposite side and read codes again. If the code changes to the other bank, you know that sensor is bad. If the code does not change, look at another condition causing a lean condition on that bank, such as a vacuum leak or fuel delivery issue.
