Bosch o2 Sensors? P2098

[whitejeep05]

Hey guys,

I was getting a code specifying the downstream sensor on bank 2 was bad so I bought a bosch sensor at the auto part store to replace it. I swapped it out, cleared the code, and everything looked good for a week. Well my CEL came back on but this time with a different code: P2098 which means a lean condition as read by the downstream sensor on bank 2 (the one i replaced)...

I read several people complaining about bosch sensors, but others saying it was fine. Could this p2098 be caused by this sensor? I'm kicking myself a little for ignoring the people who said they were a problem...

Any feedback would be great...

Yeah buy a NTK O2 sensor and throw that bosch one in the trash were it belongs.

The KJ will work well with the NTK's.

Bosch..:thumbsdown:

Bosch might be fine for a VW .... but OE is best here. And sometimes the same price or less.

Heck, I worked at the auto parts store at the time, and a Bosch O2 didn't work real well in my Ford either. They are very finicky about what cars they perform well in.

There were several people saying they didn't have any problems, and it was what my local store had in hand, so I thought it was worth a shot. Turns out i was wrong... should have listened oh well

Well that *****, I swapped to an NTK sensor and I have the same issue UGH

Question. Is the sensor for bank 1 and bank 2 the same for the upper and the same for the lower?
I'm getting mixed feedback and about a $30 difference in price.
For example the uppers are different part numbers for NTK and vary by $30 / other brands say will work left or right side upper

Chrysler=NTK 02 sensor.

I guess it's all about luck? Like a few others, I've bought 2 Bosch sensors and my Jeep doesn't care. It hasn't had a problem yet and performs as it should. I guess I got a good batch of o2 sensors? Lol.

I bought the 4 different NTKs from Rockauto when I needed to do mine. I think they were all different wire lengths. I thought the upstream and downstream connectors may have been different.

Edit: This is for the 02. I see for my 05 the upstreams are the same PN and the downstreams are the same PN.

BTW Bosch didn't work for me in the KJ either but were recommended and worked fine for my old Pontiac GrandAm. I think it has something to do with response time and how that relays to the computer.

Thanks you And yes I have an 02, and I'm also going to order from rock auto.
My GMs prefer denso as the Bosch are slower and makes for a tuning nightmare and ses lights.
Cool. I'm gonna order those 2 uppers then.

What would a lean condition be caused by if not an o2 sensor?

Vacuum leak,plugged injector(s),bad fuel pump,and exhaust leak before the upstream O2's to name a few.

My KJ seems to have somehow adjusted to the high altitude and lower oxygen levels over here.
Whenever I drive out of state, and drop a couple thousand feet in elevation, P2098 pops up. As soon as I get back home, it disappears by itself :roflsquared:

For what it's worth, partsgeek.com lists the same NTK part number (17925-01110375) for both upstream and downstream.

However, rockauto.com has different NTK part numbers for upstream (23160) and downstream (23159).

Lol that's exactly what I mean, the conflicting info had been throwing me off
