Default P0172 and P0132 + Engine Hesitation

Hi All,

I'm getting codes P0172 (Fuel System, S1 B1, System Rich) and P0132 (O2 Sensor, S1 B1, Voltage High) from my 2005 Dodge Dakota (3.7L 4WD).

Runs fine for a couple miles, but when I park it, and drive again shortly after it hesitates ALOT when both idle and driving. When it's hesitating, which is pretty constant beyond a quick drive, it's hard to get it up to speed.

Was reading online and in this forum and found a good bit of people with the codes separately, but not many together (without other codes). My muffler has at least a moderate leak, and I'll be replacing that shortly and also going to try replacing the upstream O2 sensor. My biggest question is what else (if anything) could this be besides the O2 sensor and/or muffler leak? The reason I ask is the auto guy I had pull the codes said that beyond that, it could be the fuel filter or possibly something else. No inline filter that I can see so that would be some more work (yay lol).

I might just take this to my local auto shop as my inspection is due anyway (i'm also probably gonna just have them do the muffler). It's roughly a 25-30 minutes drive. Is it OK to drive it like this for that period without damaging something else? If I do end up taking it somewhere instead of fixing it myself, I'll report back either way on the eventual solution!

Thanks in advance. I'm relatively new here and this forum has been pretty awesome thus far!

Good luck with the "filter". Its basically a sock that goes around the fuel pump, inside the gas tank 😦

Yeah...that's what I hear. Drop the tank and all that fun stuff lol. Here's hoping that it's not the fuel filter (crosses fingers).

I would replace the left upstream O2 sensor and see if that solves the issue for both codes. It's possible that you could wreck the catalytic converter when running too rich.

Agree ^^

Start with the simplest thing first.

I appreciate the feedback guys. I'll replace the upstream O2 sensor and report back. I'll avoid driving it for now for the catalytic converters sake.

Regarding the fuel filter, I didn't even think of pulling the bed box. Not a bad idea. Hopefully changing the O2 sensor fixes it and the filters still in good shape and I don't get to test that out yet lol.

Thanks again.
