2005 Tiburon GT - Outside temperature sensor
Hello All
Does anyone know where this is? Hyundaitech? Yesterday for the first time the readout was clearly incorrect since it was reading a steady 60 deg.F while the outside temperature was clearly over 72 deg.F - by thermometer and by feel. This morning it seemed to be back to its old self - adjusting itself after a minute or two following startup. Maybe it is starting to get flaky.

Most likely it was a dead short between the driver's seat and the steering wheel :-P Eric |

Your ambient temperature sensor should be mounted to the vertical support
in front of the radiator. Because of its location, there's complicated logic involved in whether the control head uses the temperature it reads from the sensor or keeps the old temperature. The logic is intended to not allow the heat from the radiator to influence the temperature reading. Unfortunately, I know of nowhere where Hyundai specifies what logic they use for this. |

Thanks for the good info (as usual). I will have a look and make sure there is no debris or anything there. When I drove off and noticed the constant 60 deg.F reading, it was sitting on a concrete parking lot in open sun -- a situation that tends to give an initial false high reading. Normally, after driving off the read temp would drop to the correct temperature. In this particular case, it was behaving counter to that. Have you seen m/any complaints regarding this sensor in your shop? Regards, Wayne Mose |

Hello Eric G.,

I can't speak about Hyundai yet because it has been OK so far and I've not had it during the summer. On my Buick, even on a very hot day, the temperature would not always show if it is higher than the last reading when the car was shut down for only a few hours. If I did not use the car all day, it would usually be on the high side as you note, then comes down after drive off. If the actual temperature was lower, it would come down to the correct reading very shortly after the car is moving. If the actual temperature is higher, I'd have to drive for at least 3 miles before the reading would go up. It is possible to take a couple of short trips, say 1 to 1.5 miles, and have the reading the same as the earlier low reading. The reason for the lag to increase is so that sitting in traffic the sensor is not quickly fooled by engine heat. The there was the day I was listening to the radio station. 101.0 FM at 1:01 on a hot summer afternoon when the temperature was 101 degrees. I thought the computer just went crazy for that moment. |

Haven't had any complaints with Tiburon. I believe there are TSBs about
inaccuracy on Sonata, Azera, and Santa Fe, however. What may have been happening with your car is that the control unit thought the higher actual temperature was influenced by the radiator, so it kept the cooler temperature instead of changing. |

I must say that I have not paid as close attention to this as you have with the Buick. Thanks for sharing the experience though. In my case despite the temperature difference between shut-down and start- up it always took a minute or two to settle down and read right.

Could well be. I guess the logic was not designed for the strange Houston weather we were having the last few days - quite cool in the morning but getting pretty warm in the afternoon. I will have to keep a closer eye on it. Thanks again. Best Regards Wayne Moses <wmoses@houston.rr.com> Fri, 15 Dec 2006 22:38:20 -0600 === Posted with Qusnetsoft NewsReader 3.3 |
