#94 of 116 o2 sensor bank 1 sensor 1 Toyota Highlander 2003

I just completed my change out after following some advice from posts 4360 and 4362 in the Maintenance and Repair forum. It is very difficult to get a good look at the sensor but once you get your angle my technique itís not that bad. Go from under the car. I used a 7/8 open end wrench. I then pushed a pipe against the bottom of the wrench while lying w/ my head towards the back of the truck. I was able to now hit the end of the pipe w/ a hand sledge about 10 or 15 times until it loosened. I did use WD 40 first to lubricate (watch for dripping). When it came to unplugging it from the harness. Be sure not to unscrew the sensor all the way you will need the tightness of the wires to unplug. I first practiced on the other "easy to get to sensor" right under the hood connected to the manifold. I was able to the just grab the clip (since I practiced) and pull the wire w/ one hand from under the car. It just popped out no problem. I did disconnect the battery to reset the computer and so far after a couple of miles no check engine light. Crossing my fingers.

did this fix work for you. Did you ever ever change the last o2 sensor after the cat.

As many forums that I have looked at, I am a little confused about which sensor is easy to see near the manifold. Diagnostic says bank 1 sensor 1, but some say it is right there and easy to see, and some say it is near the firewall on the other side of the engine. I went to Performance Toyota and the parts guy refused to sell me the part because he wanted to take the suv to his shop and that I am not qualified to change it. Anyone have any luck finding right part and where did you have it switched out?

Its all in 4360 & 4362 in the Maintenance and Repair forum. Assuming you have a V6, the Bank 2 sensor is staring at you when you open the hood, Bank 1 is near the firewall.
Your "parts guy" is either misinformed or lying.

Thank you very much for your info. I do not have a lift nor the equipment to do the job. If the parts guy is shaky, would you trust the service guy at the same place?
#100 of 116 Transmission fluid overheat light
Jul 27, 2011 (3:49 pm)
After servicing my 03 Highlander, was taking a trip and the trans o/h light came on. I pulled off the road and before I even got stopped, the light went out. Continued on the trip and after 25-30 miles
had the same thing happen. Again, pulled off and again the light went out. Went to a local dealership to have things checked out. The tech checked things out and could find no problems. Fluid still red and no burnt smell to the fluid. Left the dealership in good shape but the cycle happened again only after 50 miles. All of these cycles have happened on the interstate doing 65-70. There is no hard shifting, slipping, or any other noticeable issues. The vehicle was not close being over-loaded. Does anyone have any ideas what could be causing this?
#101 of 116 Re: CHECK ENGINE LIGHT ON AT 62K ON A 2003 HIGHLANDER [angieth]
Aug 22, 2011 (6:16 pm)
Toyota Highlander 4C, 2001, at 65K I replaced the Climate Control ($1,200), after couple of months I had to change two oxygen sensors ($450), I had to, otherwise car wouldn't pass smog test. I got I first car 15 years ago, it was a Ford Thunderbird with 73K on it and don't remember spending so much many. Maybe Toyota used to be reliable before, but NOT ANYMORE! Speaking of the Toyota dealerships... prepare to be robbed, and be thankful that they don't rape you pfysicaly as well...
#103 of 116 sensor problem
Oct 17, 2011 (8:40 am)
I have a 2004 toyota highlander. ~ 6 mos ago had a check engine light come on and changed the air sensor. The check engine light has come on periodically since and goes out after an hour or so. It has not come on for ~ 2mos. Today had an inspection and although there are no error codes the emission will not pass because multiple sensors say 'not ready'. There has been no battery changes or jumps in hundreds of miles. The car has also developed some hesitation with acceleration...any thought?
