Ok, here is my deal. I have a 2001 1500 4x4 regular cab, 5.2L, Manual. I had an issue with it stalling and sputtering and what not around 2k. After running for about 10 minutes it would be fine. A dodge tech told me to replace the intake plenum gasket, which seemed to fix the problem for about a day. I do have a check engine light still on indicating my upstream oxygen sensor. I can not get the correct sensor for the life of me. I have now purchased 3 different ones and everyone I get in the mail is the wrong one. I one sensore right before the cat converter and one after. Both have the same square connector. The one most places spec out for my vehicle have a round style connector for before the converter. My stock sensor measures about 12 inches from the threads to the end of the pigtail. I have a Bosch part # 13122, and also a Denso 234-4076. Neither of which are correct.

HELP!!!!!!!!!!!!

Thanks guys

 

welcome to the forum

i was actually looking at oxygen sensors last week,(Upstream, before CAT) for i have just repaired my plenum. i went to autozone, and the had the correct one, in fact it looked exacally like the one i had on there to begin with (stock 02sensor) so i dont know if you've tried AutoZone but the have the round connector

 

just cut the harness off and hook it to the new sensor.

 

yup, autozone was the first place I tried. But what you said is what my problem is. Everyone sells me the round style connector. Mine is square.

 

then like said above...cut the wires off...and splice them together(if you know how to do that kinda thing)

 

im sorry im misunderstood, i thought you wanted the round tip....but yea do like everyone else is saying, and if you get a universal with a square top...those are easy to wire in.

 

Take it back to the parts store and look at ones from different years. They changed the plug a couple times.
