Where is the Ambient air temperature sensor located - what does it look like?
Usually behind the grill, in front of the radiator or to either side of the radiator.
On a 2000 Durango, the MAF sensor is known as an "ambient air temperature" sensor. Follow your air intake to the manifold. It's sticking out of the right side, under the manifold and looks like this: http://www.autozone.com/autozone/catalog/parts/partsShelf.jsp?displayName=Sensor+-+Ambient+Air+Temperature¤tPage=1&categoryDisplayName=&navValue=16001729&itemId=prod10194&parentId=cat10015 Good Luck.
Ambient refers to the temperature of the surrounding air, i.e not at parking lot level etc. Ambient means the temperature not being effected by mechanical means, like AC or any heat source. example, if you serve a wine at ambient temperature, it is not a specific number it is what ever the room is at the time.
If you have a 1989-1995 model 325i, the ambient temperature sensor should be part # 65818350779. Best way to see a picture is do a Google image search on the part number. It will look like a plastic piece, black on the probe portion, yellow on the plug-in portion, with 2 round electrical connector pins.
What is the location of the ambient temp and in car temp sensors for heater control in a 1994 Buick Roadmaster?
These are usually mounted in between the outlets for the vents on the edge of the dashboard. You will have look closely to see it/them, because they are no larger than about a 1/4" square. It/they will have a tiny grill covering them. In additiona - the outside temperature sensor is located in front of the radiator support. It looks like a little horn.
Th ambient air temp sensor tells the car what the temp is and regulates the climate control to keep you cool or warm.If it goes out and it can read the out side temp as 30 below and not allow your air to even work. I just replaced mine on a 2003 bravada it was very easy to replace and the sensor was like 4 bucks
Answer The coolant temperature sensor is located in the coolant housing on the transmission end of the engine under the ignition coil. In my experience, most of the problems with this coolant temperature sensor are intermittent, so attempts to troubleshoot usually prove fruitless. If you'd like, you can view the schematics for the vehicle in the ETM section at www.hmaservice.com. You'll need to register for a free account, and the site requires Internet Explorer.
You can get the part right from a Chevy Dealer. They go out often enough that a good part's manager will have them in stock. There are 2 parts. One with a bracket and one without. The bracket is for crash repairs so you will not need it. The part you are looking for only ran me something like 3 bucks.
