newbie needs oxygen help

doorslammer · 10-18-2008, 07:38 AM

Hey all, landed here by random surf. My girlfriend has a 1998 Tundra w/ 2.4L. The oxygen sensors need to be replaced.The one under the hood Helen Keller could find. There is supposed to be another one somewhere else on the truck we haven't had a whole lot of luck finding it or a manual that shows it. Can anybody throw us a bone on this? Thanks Mike

it would be located after the catalytic converter, which is more than likley located under the vehicle....

Thank you Stumpuller454, the catalytic converter was exactlly where you said I"d probably find it,and the **** sensor was loitering in the same spot. I can build you a piano from a picture, but the car thing kicks my butt. Have a great day

Welcome to the site:

What are the odds of two sensors going bad at the same time?
Are you sure there is not another problem? Once in a while simply dirty injectors can cause a lean cylinder that will result in a random misfire code, and often can come back as a bad O2 sensor.
What gave you the indication that the O2 sensors were bad?
