    Hi, my check engine light has been on for awhile and I pulled the code like 2 minutes. Came up with " O2 Sensor Circuit Slow Response" ( Bank 2 Sensor 1)
    Where is this sensor locatated and is it hard to fix? I dont think Oxy Sensors would cause any long term harm.
    Thanx,
    97Xplor

    It's the oxygen sensor on the left side closest to the exhaust manifold.

    This code IS usually caused a dying O2 sensor... the rapidity with which it "crosses over" the .445 volt "ideal" does not happen as rapidly as it should during a cycle test (not the right name, but you get the idea, somewhere in a drive cycle the computer actually varies the fuel mixture and watches what the 02 sensor does.).
