Don33 Posted April 13, 2008 Share Posted April 13, 2008 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?. Quote Link to comment Share on other sites More sharing options...
texagun Posted April 13, 2008 Share Posted April 13, 2008 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. Quote Link to comment Share on other sites More sharing options...

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.

bigste Posted April 14, 2008 Share Posted April 14, 2008 Your display shows the ambient temperature. That is to say it shows the temperature in the shade, not in direct sunlight. Quote Link to comment Share on other sites More sharing options...
Don33 Posted April 17, 2008 Author Share Posted April 17, 2008 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. Quote Link to comment Share on other sites More sharing options...
