Analog clock? Dunno what you're talking about.

You could have a bad or disconnected external temperature sensor. On stock vehicles, it's usually in the front bumper. You've done some bumper mods, so you would know better than I where to find it now.

Should be a bad outside air temp sensor.

Il Simo, that should, without a doubt be your ambient air sensor. mine did the same thing. it is located in your driver's side brake vent, kind of behind your fog lights. if that doesn't help look it up in the bentley manuel.

Keep in mind that maybe you do not have an external temperature sensor, since your car did not come sctock with an OBC. I am sure that should be easy to retrofit, though. -35ºF is the default reading when the sensor is either absent or faulty.

can anyone show me a pic on where exactly the sensor is located? I found a unused connector so I'm wondering if it is it. (yellow in color)

drz · 03-08-2006, 01:15 PM

The yellow thing is the sensor, usually. Show us a picture of what you have. I cannot go out to my car at the moment.

hehe neither can I... I'll get it posted tonight

Il_Simo · 03-13-2006, 10:27 AM

excuse me...

I have this connection diagram where the letter (A B C D...) are the pins on the connector but I don't know that pins they are.

this link is a EBA file to install the obc 7 buttons but I don't understand why there aren't the numbers of OBC connector.

Yes the sensor you are looking for is yellow in colour, It is supposed to be located on a clip at the back of your front skirt next to the air intake for the brakes. hope this helps a little?
