I have changed out both sensors Twice on my 2001 RX. The same idiot lights came on a month ago; cel, trac, vtc. Then after about two weeks, they went off. The car is garaged in the winter and I use gas stabilizer over that period. Is it probable that the additive causes the issue? Car has 87k on it.

 

Welcome to Club Lexus.

Can you please list the actual error code before the fix and after the fix. Also are you using OEM sensors or aftermarket sensors.
