o2 sensor

Howdy! Just joined I have a 1993 FZJ80, got CEL code 28, for O2 sensor no. 2. I have the new O2 sensor, however the currently installed sensors direct thread bolts are rusted to nothing. I cannot find anywhere online or in forums the size and treatment I need to replace these. Additionally...

I have a 2000 with 282k miles and it’s throwing a code for the bank 1,sensor 1,02 sensor. Is this something I need to replace immediately or can it wait? Is there any other maintenance that should be on my radar with this mileage? Thank you!

ISO part numbers: 89465-69065 89465-69075 Or compatible O2 sensors for 1993 80 series. Looks like my only options are Walker or maybe Bosch, if anyone has any insight on those please share. Thanks

I have a 1993 80 series. Looking for O2 sensors. All the past treads have part numbers that are either both current or discontinued. Does anyone have updated parts numbers?

I have two new in package OEM Toyota O2 sensors. Part number 89465-69115. $300 shipped conus for both. Let me know where I can send pictures too. Email or text works. PayPal or Venmo. For PayPal add the fee if you want G&S. Shipping out of Texas.

I recently purchased my first FJ80 and this is my first post on here, I can't thank everyone enough for all the posts on here as they have been an enormous help on several issues. However my current question and problem is in regards to the upstream O2 sensors on the exhaust downpipes. On the...

Hi guys, My 1993 80 series has been having o2 sensor issues, its throwing codes, 21 and 5. Ive replaced the old o2 with a new one from online auto parts and it hasnt fixed the issue. Im getting 12v to ox1 on the diagnosis board when from what i know its ment to be between 0.9-0.1v. For a bit...

Hey all, I have a bit of a niche question. So I have 07 FZ-FE Cruiser from Dubai. I have been having real issues with fuel mileage and a bit of a shaky idle. So I have been trying to do some diagnostics on it and it came up that the upstream sensor on bank 1 was having issues. So I ordered the...

NGK NTK 24044 O2 sensor. Made in Japan. New unused. I opened one box just for photos. $150 each, two available.

So I recently replace my exhaust system from the manifolds back and the job went really well. Like a little too easy. Job was done cranked it up and still had the reoccurring code 28.... so I dug in a bit and started tracing back wiring. I find that the previous owner had spliced the O² wiring...

Im importing this FJ40 next week to Florida. My guy has done an amazing job with 99% of the build. We transplanted a 1FZ-FE into it and it runs very well for the most part. It needs to be tuned properly and probably needs a new O2 sensor installed. He just doesn't have access to the equipment...

G’day everyone, new to this site so if I post in the wrong place please excuse me. I have a 2004 Sahara landcruiser with the 4.7L petrol engine (2uz-fe). Up until recently it has run like a dream, but now I have started getting a few issues. It started with the o2 sensors. First a bank 1 sensor...

so last weekend i was plowing snow with the 80 and my exhaust from the CATS was always questionable. leaked and just getting me by. so anyway i got stuck in the snow last weekend and while i was rocking it out the snow got wedged up around the CAT and removed the rusty pipe between CAT and...

Driving myself crazy with this one, as it's causing me to get a whopping 8 MPG. Consistent P0125 code with intermittent P0130 and P0133. FSM points to a bad O2 sensor, wiring to the O2 sensor, or bad ECU. Replaced sensor with Denso, no change. When I run my scanner, I'm not picking up any...

Where did you get your extender? I'm thinking of putting one past the convertor. Got a 402 code. Please send link of extender that will fit. Thanks Gman.

On the drivers side towards the back of the oil pan. The connection that’s taped to looks like it goes into the o2 sensor so I’m thinking it may be related.

Hello my fellow GXers! Here is my experience replacing the upstream O2 sensor on the passenger side:

Getting through baselining my new to me '93 FZJ80, and my next big project will be replacing the coolant hoses (to include the PHH and the heater control valve). Before doing that, I'm thinking of doing a PAIR delete. Some background... When I first bought the truck, there was an exhaust...

97 FZJ 80, European spec., delivered to Finland, no OBD2, 1FZ with 360 000 km on the clock. for the last 2000 km (starting in the dunes of Grand Erg Oriental/Sahara desert) the CEL came on intermittendly. When trying to get a code with the paperclip method: continuous blinking and after...
