I hate rust. The nut was pretty much falling apart in the socket, so on friday it goes in to the shop. At least I started it for them...

not overnight, but I let it sit for about 15 min.

On the can it just says let sit for a couple minutes before doing anything, and longer for more difficult applications. figured 15 min would be enough.

Might run to sears tonight and pick up a set of bolt extractors and work on it some more tonight.

The head sheared off? Maybe get the other bolt out, lift out the sensor and see if you can vice-grip what's left of the broken one out.

Don't wanna get you in over your head, but how good are you with a bernz-o-matic torch?

a what?


The nuts are rounded off. If I get these you think I could get the nuts off with them? I'd have to get new nuts, but that isn't a problem.

Worth a shot. But I think I'd just run by a muffler shop and ask them if they can finish getting them off for you. I'd bet most little mom-pop shops would do it for very little or free.

6 yr old thread , But usefull P0031 code so I found the first O2 upsteam of cats. This is what this code means on a 04 Tacoma 4X4 V6 SR5. Looked at the mounting up stream of the Cat and used a box end 13mm to work the nuts off, Move it a little to left then right, back and forth, Move it a little out, move the nuts in. These exhast connections need to be worked back and forth to unload the threads from the rust that has built up . Both nuts come off with no pent oil! (I was out off pent oil.) Trace the wire up to the manual transmisison top , pull the covers off the manual trans sticks and locate the connector. Read that the connector needs to turn back towards the transmission sticks to get to the connector latch. So I remove the O2 sensor so I can get some slack in the cable. Break(on purpose) the mount from the connector to the transmission with a screw driver( I just pried the mount until it came lose which broke it) Un latch the connector by inserting a slim screw diver in the latch and pulling on the connector( gently) at the same time. Lower the O2 sensor to the ground and remove. Call up the local parts house (O`Reilley) and they can have a Denso here tommorow for $138. Denso is OEM, I can see Denso marked on the old one. The hardest part is getting at the connector to unplug it and that wasn,t very hard.

Thumbs up

Anybody have a Denso part number? All I can find is the downstream one.

2003 3.4l MANUAL

Found: DENSO Part # 2349003 {#8946735021} OE Style
Upstream; Standard trans.


Current discount code is 2456485322894504 (good through 10/18/2014)

So, $111 shipped. Gotta love Rock Auto. USPS or FexEx shipping means you never have to deal with the stinkin' brownshits, ah, I mean brownshirts.

Has anyone ever seen the o2 sensor cause problems ( bad fuel economy, crappy acceleration etc) without throwing a code?

Yup, dropped about 3-4 mpg's for a few months now. Just threw the P0125 code last week, part came in yesterday. Since it's the A/F you are potentially running rich and unable to enter the closed loop function which uses more fuel then necessary.
