Answer
Many things can cause a check engine light to come on and the O2 sensor is just one of them. This car is 16 years old. I can think of many things it may need. I would replace every single vacuum hose, spark plugs & plug wires to start. You may also have a clogged catalytic converter. Depending on how this vehicle has been serviced, it may need more.
