The money I saved by doing this myself will be put into my massive credit card bill which can only mean more room for mods and debt! yay! Seriously though, great write up.

That's what i did.. When my first sensor went out, I purchased one from the lexus dealer for $230-$240. My second one went out a few days after I replaced one of them. I said screw it and purchased an universal denso sensor. (make sure you get the right one, some have heat sensors and some do not)
1. Cut off the old sensor.
2. Put heat shrink over each wire before twisting them together.
3. Soldered the wires and covered it with the heat shrinks.
4. Warmed the shrinks and wrapped the whole thing up with electrical tape.
5. Put sensor back in.
I saved over $200 going with the universal sensor. I did it a few years back and had no problems. No noticable gain/loss in performance and no drop in mpg either.
-on a side note: The reason why 2 of my sensors went bad was due to seafoam. That screwed up my after-cat sensors.
Great instructions, it took me 20 minutes. Hardest part was fretting over how hard it was going to be. Thanks you saved me hundreds of bucks

Does anyone know if there is a brighter light bulb that will fit into the 2 brake lights in the trunk on a GS43?. And if so where to get them. I know in other countries I have seen them used as a brighter more visable parking light when there is fog but there is a seperate switch for that on foreign models. .
As for the OP, great DIY. I also used a universal sensor.
