I have a 1996 Buick Regal 3.8. The Check engine light is on for code P0140. Which is oxygen sensor, bank 1, sensor 2, the sensor after the converter. So I went online and bought one for $20 and put it in. The light did not go off so I went back to autozone and the code P0141 and P0140 came up. After a month, I finally got to the junkyard and found a decent sensor that was the same. I had to rewire the plug, (wires could be wrong, but im pretty sure there right). The light is still and I took it back to Autozone and the same two codes came up. Whats the next step? And can the wiring be wrong, hurt the O2 sensor?
Thank You In Advance
have the same problem?
