cadillacjeff7777 Posted August 2, 2011 Report Share Posted August 2, 2011 Today when I got in and was driving my 08 DTS, the Ext said 82 as I drove around town. After about an hour it said 83. I checked and it was 111 outside. After a little bit longer it read 110. I figured that the temp had dropped a degree and it was readable...But it continued up to 113 and then 114. Anyone know what's going on? 2008 DTS Link to comment Share on other sites More sharing options...

Anyone know what's going on? Probably a faulty ambient temperature sensor or dirty connector/damaged wiring. Sensor will be located in the air stream in front of the A/C condenser (hood latch support?). Get it fixed because your interior temperature control is fine tuned by the ambient temperature signal.

Texas Jim Posted August 2, 2011 Report Share Posted August 2, 2011 Mine does that ... but only after I have just had it washed... The sensor has to dry before it is accurate... My first thought was... check the wires/plugin under the hood in front of the radiator... Considering how hot it was today... the 113/114 part might be correct.

Thanks Been there ... done that ... way too many times to count... :) The second time mine did that... I headed for the dealer, which was only about 5 miles from where I had it washed at. By the time I got there, it was ok. As I drove by I saw a couple of guys washing some of the new cars on the lot with a portable power washer, mounted on a truck. As he was spraying water thru the grill I had my "EUREKA" moment...and was really glad I had not actually pulled into the service area and have everybody laugh at me. :) Link to comment Share on other sites More sharing options...
