I just had the spark plugs, pcv valve and the O2 sensor done on my car and I wanted to know how long does it take for the check engine light to go off because I had to turn off after the stuff got done but it came back on. I had the codes read after everything got done and it still reads O2 sensor?

Could be wiring problem or the computer if it refuses to clear-The O2 sensor is it OEM part?
