What can I do about a defective oxygen sensor in my car? It was replaced 14 months ago.?

Answer 1

Replace it again.

And check your mass airflow sensor. If it goes bad, it will mess up the fuel mixture and cause excessive fuel to blow through the exhaust, possibly damaging the o2 sensor.

Answer 2

replace it hope it not cat- converter

Answer 3

change it! i went through 4 of them before i got a good 1.

Answer 4

I would think you would replace it. I sure hope autozone didn't diagnose this for you. Every code read they do they condemn the O2 sensor and sell the customer one when in reality that wasn't even the problem. That's how they make money off peoples free Code Reads.
