How do you replace the oxygen sensors on a 1996 Toyota Avalon?

Answer 1

I just got done changing all three O2 Sensors on my 1995 Toyota Avalon. First one is on the front of exhaust manifold. Second one is in front of the firewall on the rear manifold. Third is right after the catalytic converter. I ordered replacements parts from NGK.com. For the front replacement is real easy. The rear replacement requires a little patients, because it is in a tricky area. The third will require you to jack your car up on the passenger side to replace it. The connector for the third one will require you to pull the carpetting on the passenger side console to disconnect the connector. Tools required to do the job: 22mm open end wrench, Floor jack or your tire jack that comes with the car. ( Recommend Jack Stands for safety and rear blocks in the back of the tire)Take you time when installing new components. Disconnect the battery to reset the computer for about hour. (10mm open end wrench for the battery connectors) Good Luck...
