o2 sensors replaced - '99 UZJ100 (1 Viewer)

[fjinva]

I wanted to give a quick note on the replacement of the Bank 2 O2 sensors on my '99 TLC. I had thrown a code and the Bank 2, sensor 1 was bad. I got both Bank 2 OEM sensors for $120 each. I spent about 1.5 hours getting the old ones out and the new ones in. The hardest part was getting the front sensor unplugged for the harness! Tip - remove the wheel and unclip the splash guard first and save your self at least 20 minutes! Use penetrating solvent and gently unscrew the sensors. Take your time getting them out. Bank 2 sensors - passenger side - are much harder to get to than the Bank 1 sensors, of course. Anyway, the dealer quoted me ~$600 for this job, if they didn't trash the manifolds, which they said they almost always do?! Silly!

The #2 sensor nuts will be rusted beyong reuse, so get two 8x1.50 nuts and lock washers to replace them!

Easy DIY. HTH

Good stuff. Thanks for the info!

Good job. How many miles on your cruiser, and could you tell a difference in performance before and after?

 

[Jukelemon]

I had mine go not one week ago. But just one on Bank two. 115k miles. NO performance drop. Dealer put mine in for 200.00. It was there for an alignment anyway so, what the hell.

Good tech bit. Should be in the faqs. Cruiser dan could have gotten the 02 for much less.

By the way, how did your read the code? There exists 0 free OBD readers in my city so I have to pay the $90 charge to get the read. Then, my dealer being smart, always gives me a large discount. By th way and i bet most do not know this, Toyota Servicemen work on commission. At least here they do and I doubt it is a local phenomenon ( :

You can buy an OBDII code reader for around $100-200. I wouldn't pay the $90...

 

[Jukelemon]

Where and why such a difference in price.

 

[hank14]

I bought a good reader form Equus- an Innova 3100, at Checker Auto. It was $130.00 with a $30.00 rebate. Lots of them for sale on Ebay, also, where someone buys one, uses it once, and sells it.

The instruction manual and their web site has info on the codes, so you can get a general idea where the problem may be, but you need a FSM to follow the diagnostic charts before you start replacing things, or you may not ever get it fixed.

I just bought a digital multi-meter from Radio Shack today to try and find the problem with our Avalon. The code reader says it is the EGR position sensor, or something like that. The resistance can be measured to see if the sensor is in spec. If it is, you look for a short. If it isn't, you replace the sensor.

code reader $40 at Harbor Freight. Works fine.

 

[fjinva]

Only 1 sensor, the front one, was "bad", but I replaced them both on that side. I generally think it's a good idea to replace them both at the same time since they see the same conditions. You can get your OBDII codes read at many auto parts stores (Autozone) for free.

I can get a 25% discount from several Toyota dealers across the country through the TLCA discount program, and free shipping. Is cdan much better than this? That would be a good contact to have indeed.

BTW, the cruiser has 80K on the clock and has been mine since new in '99. First time I've ever had to spend a dime on it, other than routing maintenence.

 

[fjinva]

"routine " maintenence

No detectable performance loss or gain by either the fault or the fix.

I think the discount is about the same as I have gotten from other Toyota internet dealers. The advantage to Dan, and I'm sure this is the same with other I am unaware of, is he knows his stuff. Sends you what you need. Nothing more, nothing less, in my experience.

hi, new member here.

i just got the 135 and 155 code for the O2 sensors on my 98 LX470 w/196K miles on it.

I got denso replacement sensors for $50 bucks each on ebay, and I've been searching all over the internet for a how to. I havent done this yet, but I have a question on the #2 sensor nut that was rusted. Arent the sensors self threading? O2 is the #2 sensor the rear sensor thats different?

thanks in advanced. great to find a forum with more technical posts!!

 

[hank14]

Welcome to the board.

You may be leading the pack with nearly 200,000 miles on your UZJ100. How many of those are yours, if you don't mind me asking?

For $10.00 you can access (24 hour access) Toyota's Technical web site and download all the FSM's, TSB's, and other info.

Good Luck.

wow, quick reply and a link to more info!

I LOVE THIS PLACE

LX was bought new by my parents and most of the miles are highway miles. They recently got a cayenne turbo, so they asked if I wanted it since it wasnt worth the trouble of selling. So what the hell!!

So far so good on it. No major malfunctions. It does seem low on power compared to a newer LX I drove recently, and the braking is much worse compared to the newer one. I got a vibration from a stop that I will post about in a separate thread.

Thanks again, any other input or advice on th2 O2 would be greatly appreciated

........LX was bought new by my parents and most of the miles are highway miles. They recently got a cayenne turbo, so they asked if I wanted it since it wasnt worth the trouble of selling. So what the hell!!..........

A little OT, but I'd be really interested to hear how your parents' "ownership experience" turns out on the Cayenne when it's got only half the miles your LX has on it! Don't get me wrong, the Turbo is a REALLY cool ride, but I wouldn't want to own one past the end of the warranty..........

 

[hank14]

In the same light, I'd be interested in knowing in a cost of ownership analysis on a 6 year old Landcruiser with 200K miles (per mile).

 

[chukiechz]

I agree with dnp. That thing is definitely a monster, but I dont know about ownership after warranty. Its got twin turbos, but no built in turbo timer. My parents just drive cars, they know nothing about idling the car after driving to let the turbos cool down some. I know after a while those turbos will be fried, and I betcha they wont be cheap. Plus, tons of little "gadgets" inside that I know are gonna go bad sooner or later. I think the newer the car the more its prone to trouble. My 03 C32 AMG has been in the shop already for lots of little malfunctions. Im also afraid whats going to happen when my warranty is up

Costs on my LX I must admit have been minimal. The thing just wont quit. Besides the O2 sensor, there has been no major problems. There hasnt been any other costs besides the regular oil changes which i do myself. Most of the major components are still working. Shocks are still working (rebound adjustment), "air" suspension still works, AC, radio, etc.

knock on wood.......

This past weekend I also just had the bank o2 sensor replaced. I have a 99 w/ 75k on it.

The front sensor (by the manifold) is threaded, the rear sensor (right by the cat) is not. Uses two 12mm nuts on threaded posts and has a gasket as well.
