Hi,
There are two oxygen sensors. One is located where the catalytic converter bolts to the down pipe from the engine (see pic 1 below). The second one is after the catalytic converter and before the muffler.
Since this is a 4-cylinder, there is only one bank. Sensor 1 is the first sensor back from the engine, the one mounted on the inlet of the catalytic converter. (See pic 1)
In pic 2, I circled the sensor needing replaced.
The last two pics are the directions for replacing it. Take a look through them and let me know if they help.
Note: You will need an O2 sensor socket that is designed to not damage the electrical wiring at the sensor. Most parts stores should lend one to you.
Take care and let me know if this helps.
Joe
