Question about 2001 Toyota Tundra
Dont have a toyota wire diagram that came with universal oxygen sensor (Denso). Is it safe to assume that the 2 blacks on the new sensors go to the 2 whites on the plug? And the white from the new sensor goes to the grey on the plug? And then the blue from the new sensor goes to the black on the plug? This is following diagrams of same wire codes of diffrent vehicles.
I would return that one and get the correct factory one. it will work better and theres no issues with wiring either. its worth it

Easy, takes 10-15 min for all of them. But there a oxygen sensor tool you can buy that makes it A LOT easier for $10. It a matter of (LIKE TAKING OUT A SPARK PLUG) JUST BE SURE TO ADD ANTI SEIZE TO THREAD IF IT DOENS'T HAVE ANY. Also i work for bosch that makes these and the aftermarket is the same part even tested the same. it may look a little different but it's function is the same.

oxygen sensors are on the exhaust. its just a small sensor with 1 or 3 wires. bank one meens left. if its a v6 or v8. but 4 cyl engines only have one bank ,. sensor 1 meens its before the catylitic converter. sometimes right by the engine manifold and sometimes way under. just follow the pipe from the engine to the cat and u will find it. if u can get it out the new one is easy. the problem is they usualy rust in tight. they make a special socket just for them. try some PB Blaster its no joke the suff makes WD40 look like cooking oil.lol.

I'm not sure what kind of universal sensor you got but having been in this business for over 25 years and own a shop now I would like to make a suggestion to you. Take the universal back. Your system has a heated O2 sensor and a universal will just not do the job and you may still get DTC's (the engine light will come back on). Even if you need to go to Nissan and spend a little more money for the sensor, it will work correctly. Even though your vehicle is older, it still depends on readings from the sensors to the computer in order for it to run right. This may also help gas mileage by putting the correct one in not to mention if your vehicle runs richer or leaner you will end up doing a tune up on it sooner then normal so the extra money you spend now will pay for itself later. Your not my customer so I'm not making money off of you just trying to give you a tip. I hope you take the advice. If you do still want to put the universal on you may end up contacting the manufacturer in order to get the correct wiring for it unless someone has it on here but they would still need to know who made it.

The wiring diagram shows the wiring color code, Power rating
and connector plug used. The wiring diagram explains the vehicle's electrical
connections with color code. It's a bit complicated to understand.
