    There will be an air temperature gauge somewhere in the intake tract. Without having a Regal myself I can't tell you where it is, but it may be in need of a replacement. There's no moving parts, so that's surprising. The way these sensors work, is that as temperature goes up, resistance goes down, so perhaps there is a short somewhere that is also causing this.

    I'd hate to rig something up, but as a last ditch effort you could wire in a 5k resistor, or a pot, to make the engine think the temperature is "normal". Many people do this to trick the engine into thinking the air is cooler and get a richer mixture (this is all over ebay). Wouldn't be my advice, but it's an option.

    Yep, goofy sensor I would think.

    just verify that the air intake to the airfilter is connected correctly. Could be that something has come off, and you sucking heated air from the engine compartment.

    Hope this might Help.I replaced mine it was kind a hard locating it is a brass part with a electric plug on, located under some black hose right side by manifold. Mine that I replaced turned green it was hard to get too would of been easier to take thermostat out and remove radiator hose connected to the thermostat, jut to get a better angle on it. This was on a 2000 Regal LS but allot of parts are the same good luck, from TXmilew
