Re: 1999 RX 300 O2 Sensor



The replacement sensor is an OEM one, I'm not sure if it is the
correct one or not, it is possible that the dealer gave him the
incorrect one. How would something strip coming out if it was
installed properly? I've never seen any bolt that if installed
correctly would not come out correctly.

Hello,


I was helping a friend replace his O2 sensor in a 99 RX 300. I
had a very difficult time all the way through getting the sensor out
with the little room to move a wrench but I did finally get it out.
When I tried putting in the new one, it would catch on the threads,
but when i put some force on it, it would just pop off again. I am
guessing that the threads are stripped. He did purchase the car used
with 25k miles in 2002. Is it likely that the factory stripped this? I
couldn't imagine that this was replaced at 25k miles. Any input would
be appreciated.

Thanks,
Nick

I have never seen a stripped thread on a Toyota from the factory. Sorry to
say this, but if the threads are stripped, it probably happened when you
took out the old one. Is the replacement sensor an OEM sensor or an
aftermarket one? If it is aftermarket, is it the correct one?
