98 TJ O2 sensor
 

Hi guys,
Has anyone changed their O2 sensors on a 98 TJ, 6 cyl.? My check engine
light has come on several times due to an upstream o2 sensor fault. I went
ahead and bought both sensors. The new downstream sensor is too big to fit
into the cat. Its a Bosch 13272. The sensor I removed has a narrow tip, it
looks like the upstream sensor. The new one has a shield of some sort that
will not fit into the cat. I searched the archives, some other guy had the
same problem. He ended up getting the right sensor from the dealer and it
fit, but its very pricey. Anybody have any info? Thanks. -Nick

Odds are very good that you do not need the downstream sensor.

AutoZone auto parts stores will run the codes for you (if you're in Calif.,
you have to run the codes yourself, but they will give you the scan tool to
use in the parking lot) and tell you which sensor you need.

I replaced my upstream sensor in my 97 TJ recently. Napa sells the OEM
type sensors for around $60.
