The oxygen sensor on my 92 Toyota long bed needs replacement. Where is the best place to buy a new one. Local store wants $200, WOW!! When it is installed are there any other thing that need to be done to activate it?
You can get NTK O2 sensors below:
In the USA as it is stated in the owner's manual under the section of "scheduled maintenance" the front o2 sensor is replaced free of charge when the vehicle reaches it's first 80 000 miles regardless of age and number of owners many Toy dealerships are unaware of this warranty policy or are reluctant to replace if that's the case contact the Toyota Regional Office for your state and explain your situation where they will give your local Toy dealership 48 hours to comply. On average the oxygen sensors should be replaced every 6 years or 100
000 miles or so which ever comes first.Symptons of a bad o2 sensor are poor gas mileage,hesistation in acceleration and worse emmissions,the 02 sensor is designed to function once the vehicle has warmed up which is about after 10 minutes where the thermostat begins to open then the vehicles ECU system enters what they call a "closed loop system" then the exhaust manifold's temperature reaches 400 degree Ferenheit (I think)that where the sensor starts to do it's job,may folks think that the o2 sensor is bad but an exhaust leak can cause excess oxygen to enter the exhaust system thereby fooling the sensor into thinking there is too much oxygen,there are other problems that could cause it to give false reading such as a vaccuum leak.
If you discover that the o2 sensor is bad and it is not under warranty then from my/others experience/research purchase an o2 sensor in the following order:
1)Toyota (NipponDenso now called Denso) 2)Denso aftermarket (Same as original but sold aftermarket) 3)NTK (oxygen sensor division of NGK) 4)BoschAvailable at:
NGK has a powerfull oxygen cross reference software which cross references their different part #'s into either a single,double,triple or a quad wire o2 sensors so you may find 10 or so different part #'s for your 92 pickup and all you have to do is plug those part #'s into:
Unless you are sure that your sensor is bad I would recommend cleaning the outside of the sensor. I felt that my truck ('87 p/u with a 22RE) was not running well and was using too much gas. Earlier I had blown the front main oil seal which resulted in oil getting sprayed around within the engine compartment.
While getting ready to troubleshoot the ignition system I came across a mention that the outside of the sensor has to be clean as the sensor references the oxygen concentration inside the exhaust system to the outside oxygen concentration.
Cleaning the outside of the sensor with some steel wool seems to have made quite a difference. Fuel consumption appears to be down, the engine also appears to have more power and is more responsive. Recent emission test results are HC: 57 PPM, CO: 0.054%, well within the limits for a 1996 or newer truck.
This is cheap, easiy and fast to do. I would recommend it to anyone. I would also like to know if other people see an improvment, is so the word should be spread.

Glad to offer the advice. Once you get it installed you'll need to clear the Check Engine code. Just pull out the EFI fuse for 30-60 seconds and pop it back in. Mine is located in the fuse block on top of the passenger side fender. The code should be cleared after that.
I asked this question before but didn't get an answer. What is the O2 sensor used for on a California '88 pickup with a 22R (carburetor)? I replaced mine at 167,000 miles, but haven't noticed any difference and hadn't gotten any kind of check engine type alert. I just figured I'd change it for giggles and grins. I used the Bosch with the OE plug already installed.
Any ideas?
