    Welcome to TW Jose!

    Can you provide some more info on your truck..how many miles, engine type, etc.

    What led you to replacing the O2 sensors?

    The CEL generally takes a while to go away. It doesn’t happen right away after you change them out.

    If you have not cleared the Code it will either go out next test cycle or the problem is still there.

    Remember it is the complete circuit of the sensor.

    Could be an exhaust leak between sensors depends what code you had

    usually the light goes out and it turns on but stays on more than it turns off
