o2 sensor

Had my 2001 LC parked for 2 weeks at the airport. Within 15 minutes of driving got the CEL. Threw my OBDII on there on saw that it said it was the Bank 2 Sensor 1 Heater something something. I guess it's front passenger. I reset it and it came back on within 5 min. Reset it again cold the next...

Hi folks, I'm reasonable sure I have this right but was looking for confirmation, as another member posted results in the past that claim what I am thinking is incorrect. Correct me if I am wrong please. HT1 orange HT2 grey, and +b (red/yellow)is the heater circuit? polarity should not...

Searched and searched without any answers. Here I have my 94 cruiser. Once warmed up the engine will run nice and smooth, but about every thirty seconds or so it gets really rough like it isn’t firing on all cylinders. Idles rough for approximately 10 seconds and then goes back to smooth. Does...

Yesterday, after dealing with P2447 for several months, I finally got around to installing the Hewitt Gen 2 SAIS Bypass Kit. Install went as good as expected (lost a bit of skin and blood but I've become accustomed to that). I did not install the block off plates, figured I'd save that for...

Ran Techstream before heading out to get a preliminary look at if I might pass emissions here in Denver, CO with my 02 LX.. Found some problems and will try to post the pictures or links. I'm guessing the 0.000 test value means the S1(s) is/are dead. But also, is it likely that it was a...

Trying to change bank 2 O2 sensor and it looks like the previous owner band clamped the o2 sensor as both nuts were missing from their bolts. Does anyone know what thread pitch those bolts are so I can buy two nuts and get this o2 secured to the exhaust pipe?

I'm stuck and need help please!!! (bold/underlined is the problem) I have a 2002 4runner limited 4x4. Things I've done "mechanically": - new engine (same 5vz-fe) 8 months ago - cold air intake 4 months ago - flowmaster super 40 - new catalytic converters 2 years ago My check engine light has...

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?
