Anything stick out about these codes? 0138, 1041, 0161, 0174

The jeep is coming up on its' annual inspection and needs a few things done. I have a few codes showing up with the key trick, 0138, 0141, 0161, and 0174.

So far on my to-buy-list is: bank 1 sensor 2 O2 sensor and bank 2 sensor 2 O2 sensor. Deciding between NTK and Denso, leaning towards Denso, but any input would be appreciated. I know to stay clear of Bosche.

So these be Denso downstream front 2344029) and downstream rear (2344768), correct?

Also the 0174 code worries me a bit, as it seems it can be caused by several different things, but it's not accompanied by the 0171 code, which I'm hoping means it's just a faulty O2 sensor, and I don't have to bother with the fuel pump/filter or any vacuum leaks.

Just wanted to see if anything caught y'alls eyes that maybe this is something other than just a simple 02 sensor swap.

Check your Power Distribution Center , slot #16, for a blown 10 AMP fuse before replacing any 02 sensors. If you have a 4.0L i6, the PDC is located by the battery. If you have a 4.7L V8, then I don't know where the PDC is, but am pretty sure there's fuses for your 02 sensors in it.

first thing comes to me there is a missing Alpha designation - Likely P0174 etc.
2nd I do not see which engine and or emission package - federal or california..

these 2 are same sensor, looks like wiring needs to be checked,
P0138-1/2 O2 SENSOR SHORTED TO VOLTAGE
P0141-1/2 O2 SENSOR HEATER FAILURE

this is a likely short heater to sensor return but needs checking
P0161-2/2 O2 SENSOR HEATER FAILURE

This is a lean condition BUT need the sensors repaired to have confidence in them
P0174-2/1 FUEL SYSTEM LEAN

When I see the price of OEM I think aftermarket.
When I see the quality of aftermarket I think OEM.

Sorry I should've mentioned, 02 4.0. I'll give it a double check tomorrow

My build sheet has codes:

"NAS 50 State Emissions
NBUP Ultra Low Emission Vehicle (ULEV)"

So I'm assuming that's federal. And I'll double check the wires tomorrow. I did an engine and tranny swap recently to a factory 4.0 and 42RE, it was out of an 02 as well. IIRC the P0138 code was there before the swap, the rest came afterward. I just finished dealing with a mess of an AC issue, the AC power connector was showing proper voltage, but not enough amperage, so we ran a new wire from the fusebox and a new wire straight from the battery. P0138, P0141, and P0161 were all present prior to the AC job, P0174 came afterwards. I doubt they're related, I've put a thousand or so miles on since the AC and haven't had any issues until this week.

I've never had any issues with these codes, until the other day when the P0174 appeared. It felt rough at idle, and maybe slightly underpowered, but only when in Drive. If it was in Park or Neutral it was fine.


EDIT: I completely forgot I've been smelling fuel on start up and occasionally while driving. Assuming this is related to the P0174?

The presence of P0138 can and will cause other codes. Eliminating P0138 is our starting point.

Here's my thread about it, though it doesn't seem to mention the final fix. I know I replaced the O2 sensor and spliced in a new connector to it because my original connector was melted to the cat. I believe P0138 went completely away after the new sensor and connector splice, then replacing the #16 fuse in the PDC with a 20 AMP.
