AIR FUEL RATIO SENSOR(S)

1999 Toyota Sienna

Engine Mechanical problem
1999 Toyota Sienna 6 cyl Two Wheel Drive Automatic 159000 miles

I have a check engine light due to the air fuel ratio sensors. Is there any way to cheaply or temporariliy get these sensors to behave just long enough for the computer to reset and I can pass inspection. If I clear the codes I fail on " Computer Not Ready" so I need an actual temporary fix. I would rather not spend the $200+ dollars each on the sensors if possible. The car runs great.

I was thinking of spraying electrical wire cleaner on them? What actually " goes" when they stop working right? Is it simply irreversible? Or can I get just one more temporary fix and a passed inspection out of them? THANKS for your time!

You cant clean the 02 sensors. They are uncleanable.

Make sure the wires are not corroded at the connectors or that base of the wires where it goes to the sensor isnt damaged or plugged with dirt.

What code is showing up? Why not fix problem?
