o2 sensor

I'm having a heck of a time troubleshooting an issue keeping my 96 FZJ80 from passing smog, and I'm hoping the braintrust on Mud can help me out with some diagnostic data. Does anyone have a graph showing good downstream O2 sensor data (at temp), preferably both idle and up in the 2k+ rpm...

My 94 cruiser was intermittently throwing code 28 for a heated o2sensor for cylinders 4-6. I would usually pull the EFI fuse and the code would clear for a while but I eventually decided to replace the o2sensor. I ordered the NTK part #244044 which is supposably the OE sensor for the 93-94's...

Hi all, Backstory: I recently purchased a 2000 with ~200k mileage here in New England. Windshield leaks (getting replaced this week, bad install), CEL on and throwing P0135 (Bank 1 Sensor 1 O2) But other than that, minimal rust on frame and beautiful body (was garaged most it's life) I...

I have a 1994 FZJ80 with the 1fz-fe. Looking in to a smog delete including egr, o2 sensor, etc. Cats are already removed. What all would I need to do these mods? Possible issues I could run in to? Related threads? How difficult would this be for the average guy?

Hey Mudders, I've searched quite a bit for similar posts to my issue, but I cant seem to find anything that helps explain what I'm experiencing. I'm hoping someone can point me in the right direction or has had a similar issue they were able to fix. The P0135 error is intermittent and can...

Just gonna post this up here, so maybe i can find it again later. This is a software problem, a firmware update could fix, but they will not roll it out. This throws O2 sensor codes, and then cyl codes as vehicle starts to misfire. Simple fix is to disconnect both O2 sensors in front of cat...

Hey guys. Help me please. My TLC80 have 2 o2 sensors (94 year) I replaced 1 (original toyota, very expensive) So need to replace second o2 sensor. What WORKING analog can I buy? just bought denso early and it didn't work (resistance is not correct, need 5-6ohm denso was 10-11ohm its for model...

I just replaced three O2 sensors on my 99 LC with 164k miles. The other was replaced at 121k. Since these weren't malfunctioning when I replaced them I thought to keep one of each for spares. I found a website that says to clean these just soak the sensor part, not electrical contacts, in a cup...

Yesterday, one of our 100s suffered a misfire at 3000, wouldn't pull above that and ran slightly rough once falling back to idle. Did air/fuel filters, throttle body, air flow sensor etc. No joy. Seems an impact dislodged the LH O2 Sensor lume and it suffered heat damage on the Cat pipe. As a...

First off, this is my first post but ‘Mud has been a massive resource for me these last few months. In the last year I acquired a 92 FJ80 and since I’ve slowly been building him (“Lando”) up. So far: water pump, belts, hoses, power steering pump/pulley, PCV/grommet, tires/wheels (Duratrac...

I am looking to replace an O2 sensor for an 85' 22R-E 4-runner. Are these still available through Toyota?

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...
