I think you're on the right track. Don't waste your money on a cheap brand though, I've had good luck with the Bosch sensors that NAPA sells.

this is the O2 sensor closest to the top, till now the cat. in specific circumstances it will be related to the cat yet returned, closer to the top. O2 sensors do fail by means of warmth on the wires or injury from dropping issues on them or the wires rubbing on something. because of the fact it particularly is a circuit malfunction, it would be risk-free to interchange the O2 sensor if no longer the rest looks broken.
