Thanks in advance. We had a check engine light on a long drive home today. The engine continued to run fine with no apparent loss of power. My scanner shows P0131 and P0151, which I assume are oxygen sensors. The code reader says: "HO2S11 circuit out of range low voltage" and "O2 circuit low voltage (Bank 2, Sensor 1)." The check engine light has gone out now.
Should I order new O2 sensors and start there? There are four, right?
