Where is the "Bank 1 Sensor 2" O2 sensor on an 01 sebring.

A coworker needs to replace his O2 sensor before he gets an inspection.
Bank 1 Sensor 2 is bad, but there are 4 of them on that engine.

Anyone know what sensor that is?

2001 sebring.
2.7 V6

2

probably pre cat, toward cylinders 1,3,5

sensor two is down stream, on a 2.7 it’s not in a terrible place to change. i think there is only one downstream actually b/c the two pipes merge behind the two cats, but i could be wrong, it’s been a while since i worked on one.

I guestimated that it has 1 on each manifold and 1 on each of two cats?
(if it even has two)

???

I dont really see why it would have 4 O2’s, but im not sure.

Anyways, Bank 1 Sensor 2 is generally the one in, or after the cat.

is this co worker a girl by some chance?

7

nope.
he’s a phd though?

sebring, wait… is that engine mounted inline like an intrepid or did they shove that in sideways? if it’s a sidewinder, that’ll be an easy change. it’s down in the back behind the cat.

2.7 in a Sebring is transverse, the LH plat is north/south. Bank 1 is the rear and bank 2 is the front, cylinder 1 is on the right rear. You should be looking for the downstream sensor.

Thanks.
Looks like it should be relatively easy to get to.

Sure thing. And yeah, that one’s relatively easy, usually not so corroded at that end. :tup:

All done.
He came over and fixed it himself :slight_smile:
