Outside Temperature

[Meist21]

This is a real petty question but on a 98 LS 400 does anyone know where the outside temp. sensor is located and what it looks like? I would assume it is up by the grill or hood somewhere. My outside temp. seems to be registering way to high. I wasn't sure if maybe the sensor was covered or if there is a way to reset the the thing. Still I would like to know where it is. I know I know, I have way to much time on my hands.................. thanks everyone...........

In my 92 it was located in the center just behind the front bumper re-enforcement ironwork where is was often influenced by radiant heat form the radiator and/or A/C condensor. Moved it into the right front.

That would make sense since it seems to register the cold (we are talking 15 degrees or so) temp too high. I wish there was a way to calibrate or reset the thing. I have not had it in the summer but I am sure it would not affect the hot air as much as the cold air.

Meist,

I'm still trying to dig the location up - have 99 manual - will try to pinpoint....

Thats peculiar. I thought that the outside temperature display was not added until 1993, unless you are referring to another car besides a LS400?

On my 1992 Buick Park Avenue, it is located directly behind the grille and I would guess that this is where it is on most cars. That was also the location for it on my old 1995 Chrysler.

Mine is on the right behind the grill; To see it believe you have to remove the bottom engine cover as well as the other piece[bottom air deflector-the front is attached by the front engine cover bolts] that has the overflow tank built into it.

The OAT sensor has been in the LS from the very beginning. It was initially only used for HVAC input/control.

I found it. Right where wwest said it was. Mine had some junk on it. It does need to be moved. It is right in front of the A/C condenser. I would think that would give it an above normal reading. It is a small black plastic piece that plugs into the wire harness. Does not look to hard to move. I will do so when it gets warmer around here. BTW the part sells for $19.13 at your local Lexus dealer..........

Meist21,

Here's the diagram - a/c ambient temp sensor (A1) .. Does this agree with your finding?

Sorry, just had to keep "pursuing" this for closure :D
