1 UZ-FE performance upgrade w Temp Sensor replacement?
Just wondered if anyone in the SC400 clan has noticed this same phenomenon as many of us LS guys??
Not any real rear wheel HP to speak of ofcourse but a marked improvement in driveability!

When I found mine, it was already loose from the connector. Turns out, it failed or moisture permeated inside, and was VERY corroded. After the install, I took her for a quick spin. I did not remove the ECU fuse during the removal/install because I wanted to see the results without any benefit of the ECU reboot.
Results were smoother idle and powerband. Quick acceleration. I am now a believer. Thank you CL, jasonburt and Zoraone.

ill test it. i dont have anything better to do tomorrow. haha.
the ECU will retard the timing because of knocking with ****e gas. resetting the ECU will rid that and give you a little boost in performance.

Fairly certain the part # I left is correct for your 95.
I used this same part # on 90, 94 & 96 LS 400's.
That is a toyota oem part #. There is some debate on the LS Forum as to the performance of the cheaper aftermarket sensors.

I bought a BWD , coolant temp. sensor, made in the USA, from Advance today, $29.95. The parts guy told me over the phone it was a Borg Warner, but it dosent say that anywhere on the box. It did not come with a gasket, and the parts guy informed me that none of the BWD sensors do. It also says its a Z series. Should we use any sensor safe silicone or teflon tape to avoid leaks? I havent taken the old one out yet to see how the fact. sealed it. Good catch on needing a deep well socket, as I keep some tools at a diff. location 19mm... The part # was a wt653z the invoice refers to the part as a radiator switch, but of course I told the guy i wanted a coolant temp. sensor. BTW, with my A.C. on today I noticed a lot of sluggishness pulling away from stop signs, and a jerking in O.D. at 1400- 1600 RPMs. Hope this part helps.
