Outside Temp Display

[Don33]

Lexus Fans. I have a 2002 LS 430 (orig owner)...wonderful car in every aspect for my needs and wants. Today it is 89 degrees F here in my section of Los Angeles but my outside display shows 73 defrees F. This is the first time I have noticed any inaccuracy. It has always been spot on. Other than a malfunction of one or more of the components, is there any thing that I can reset or clean or adjust or?.

Make sure you give it adequate time to respond. Sometimes mine takes 30 minutes or more to adjust to the correct temperature after being in the garage.

Just a guess, but did you just wash the car before you noticed the inaccurate reading? If the temperature sensor is wet it may read a lower than actual temperature due to the moisture evaporating off the sensor until the sensor is dry again. Other than that, I can't think of anything that would cause it to read low unless the sensor has failed and the 73F reading is a default reading.

Your display shows the ambient temperature. That is to say it shows the temperature in the shade, not in direct sunlight.

Thanks for the replies. I did just wash the car. I'm still monitoring to be sure. How do you think I got the sensor wet? Where is it located. Thanks again.
