Where is 1998 Jeep Wrangler Oxygen sensor located?

Hi All,

I got a 1998 Jeep Wrangler. I got P0138 error and would like to
replace the oxygen sensor.
Can anyone guide me to locate the oxygen sensor?

Thanks,
Pen

in the exhaust pipe, normally between the catalytic converter and muffler.

Look at the end of the exhaust manifold, right before it connects to
the pipe that goes to the cat. Make sure you put some anti-seize
goop on the new sensor's threads before you install it.

And make sure anything you put on that sensor is sensor-safe unless you
can afford to buy two of them.
