Ambient Temperature Sensor

Hi. I have a 523i series (1996) whose ATS is reading -40. Can you please advise the exact location of this sensor for repair purposes? Thanks Peter NB: It is badged as an M Series although the steering wheel is not the 3 spoke type.

    Thanks for your quick response. I found it was located on the underneath of the chasis (protected by plastic cover) beside and to the front of the right hand front wheel. There you go. I also confirmed it is NOT and M series - merely a cheap badge. Thanks.

Check in front of the radiator, it should be on a small metal bracket, the sensor has 2 wires going to the connector on it..

Temperature display isn't accurate


Hi Dale. Look under the front bumper either on the left or right trim panel. The trim panels are triangle in shape. An outside temp sensor usually sits in this area. The sensor may be missing. BMW has the sensor, wire, and connector available sperately if they are missing or damaged. It will cause the outside reading to be -40 and can cause the a/c compressor not to operate.

Air conditioner will not come on. The tempeture gage is reading -40. The sensor is not reading properly.


Hi ruswashingto,

The air conditioner may not work properly if your ambient temp is reading -40. The a/c control unit monitors ambient temp so that it does not operate at too low outside temps. I would recommend fixing the ambient temp sensor and rechecking your a/c operation.

Misreading outside temperature sensor on 2001 Audi A4


There are four sensors for ambient tempurature and they work in unison to provide information to the temp reading on the dash, the heater control head ( where to direct air, blending of warm/cold/outside/inside air flapper controls) depending on the ambient temp and the inside air temp sensor located just above the radio as well as the sun sensor on the top of the dash as well as the a/c compressor head.

When you start your car, the body control module takes the readings from all sensors, outside air temp located in front of the radiator, air temp sensor located in the airbox ( senses temp of air being drawn in from the outside into the air box), coolant temp, inside air temp sensor and the sun sensor on top of the dash (this is why it takes a few seconds for the climate control system to begine when you start the car). The intake air sensor is 1st priority, inside air second, coolant third, ambient 4th and sun 5th. For instance, if the sun sensor reads the sun is hot but the interior sensor reads cold, the inside akes priority. The goal is for the system to achieve a tempurature inside the car that matches the selected temp. It uses all of the sensors to set the system up to achieve that goal as quickly as possible.

Example; Its mid afternoon, sunny and 40 degrees outside adn your in stop and go traffic. The intake sensor reads 40 degrees, the outside sensor reads 60 degrees (heat from radiator...engine heat protrudes into cabin) and the sun sensor reads high (sun is strong). The system is set for 72. priority one sensor reads 40, inside sensor reads 65, ambient reads 60= system will blow hot air to the floor out put, dash outlets will lightly flow 65 degree air so the sun doesnt roast you yet your feet are cold(if it blew hot air from all outlets, your upper body would be hot but your legs/feet would be cold). as the interior sensor reaches desired temp, air will be distrubuted through thee dash, defrost and floor with the warmest air coming out the floor and defrost, coolest air out the dash vents. Its a complex system!

The two sensors that will screw the system up the most are the intake and interior sensors. the system will function reasonably well with just those two sensors though it wont blend air temps between outlets if the sun sensor isnt working. If the outside sensor fails, it simply uses the intake sensor, if the intake sensor fails it will rely on the front sensor. However, since the intake takes priority over the outside sensor, if the intake sensor sends incorrect resistance info rather than failing, it will take priority and cause the unit to malfunction such as in your case.

The intake air sensor can be changed from the outside with patience. If it where me, I would pay the two hrs labor and let the dealer do it right.

Temp


This reading is a default setting and it looks like the ambient temp sensor is either faulty or missing, it should be located in the front lower plastic panels under the front bumper. hope this is of some help and if the sensor is missing/damaged you will not be able to reset it
