What is your question?
Check engine light on. Already replaced (Myself) Mass Air Flow sensor. Before the MAF sensor replacement I had 3 codes: P1150, PO171, and P1155. Light came back on and now the P1155 code is the only one remaining. States air/fuel ratio sensor heater circuit malfunction bank 2 sensor 1. Now what do I do? Will a new AF ratio sensor help?

There are so many reasons any of these codes can come on and without performing some tests it's impossible to know whether there's a computer, wiring or sensor issue.
