o2 sensor

I tried doing a search and most of them on this topic are really old. I have a '94 that needs a new No.2 O2 sensor. I just got back from my dealer that quoted me almost $300 for one, even at their wholesale pricing. I am normally a big fan of OEM, but that is just too much for my wallet at the...

Good evening fine folks at Ih8mud! I'm new to the offroad and LC scene, after being introduced to the joys of offroading last summer. I knew this hobby was my next one. Fast forward 8 months and I'm the proud new owner of a 1991 beige/cedarwood FJ80. 270k miles and a bit of rust, but she is a...

The PO of my rig had someone weld up a custom stainless steel exhaust setup. Does it look like the o2 sensors are in the correct locations?

Thought I would post here to see if there is any interest in these. Mounts on the secondary O2 sensor. Asking $45 shipped anywhere in the US.

So now that we have the LC running I checked the check engine light and got an error code 28 No.2 oxygen sensor/heater signal fault. I went to go look and see if there was anything obvious wrong and low and behold I found this.. Looks like someone or something has cut\chewed through the O2...

Hey folks, My 97 fzj80 is at an indy exhaust shop today getting the over-the-frame exhaust job done. I went with the Magnaflow 23120 cat and a magnaflow muffler; going to see if I can reuse the tailpipe for now. Anyhow, the cat has one slot for the oem O2 sensor but, since I'm going down to 1...

Greetings all, I have been lurking here for a while and have found answers to every 80-series issue I've encountered, until now... Short version: I am building a custom exhaust for my 1993 FZJ80. I am switching to a single cat and would like to replace the two pre-cat O2 sensors with a...

Hi fellas. Been having trouble with my '93 fzj80. Got a really strong fuel smell coming from the exhaust so I figured I'd check all of the sensors. They are all okay, except for the o2 sensor, which holds around .35 volts on the sensor wire, and doesn't fluctuate as it should. Previously I'd...

I have a 1991 FJ that's thrown a code #28. "Number 2 O2 Sensor." Denso has two part numbers. I guess one is front and one is rear. Can somebody make it clear to a dummy (me) which one I need? A part number would help, too :) Also, my radiator gets very hot when the car runs. I mean like...

Evening, Over the past few weeks I have been trying to fix my 1994 FZJ80. It first started with a CEL. I took it in to have codes read and pulled codes 25 and 26 (air-fuel ratio lean and air-fuel ratio rich). I replaced the O2 sensor and it drove fine for about 500 miles then the CEL came back...

Hello all, Just got an astronomical estimate to repair my exhaust. So looking to collect the parts myself. I need two catalytic converters for a 1994 FZJ80 in Tennessee. Also looking to source the 02 sensors as well. I appreciate all replies! Thanks for the help Jon
