Does ambient air temperature sensor affect AC?
As the ambient temperature sensor plays a direct role in the automated function of the AC system, when it is having a problem, this may interfere with the system's ability to cool the vehicle.
Why is my car reading the wrong temperature?
On warm summer days, the readout on your car can be 10-20 degrees higher than the actual air temperatures. And that's because your vehicle is actually taking a reading of the heat coming back up off the pavement. Typically, you'll notice a very hot reading on day where we have a lot of sunshine.

You bought an outside temp sensor. Part number ends in a 133 doesn't it? If the outside temp sensor is missing or bad it can cause the compressor to not to kick on. There is not a replaceable interior temp sensor, at least not one made by BMW.
Where is the fan on HVAC?
its the little slots on the front of the HVAC control. there is a fan that draws air across the sensor. it can clog up with dirt and need to be cleaned. There should be a write up or two, but its painfully simple.
Can you disassemble a climate control unit?
You can disassemble the climate control unit to more thoroughly clean the dust out. The motor is a brushless type consisting of a small flat squirrel cage fan wheel that sits on top of a post on the circuit board. To dissassemble the unit you need an electronics Torx screwdriver set.
What is the job of ambient temperature sensor?
It is the job of the ambient temperature sensor to measure the external temperature of the vehicle as a reference point for the computer to make calculations. The computer will continuously monitor the signal from the ambient temperature sensor and make automatic adjustments as needed to maintain cabin temperature.
What does an evaporator temperature sensor do?
What does the evaporator temperature sensor do? The A/C evaporator temperature sensor monitors the temperature of the A/C evaporator. The sensor helps prevent the evaporator from overheating or freezing over by increasing or decreasing the refrigerant flow through the A/C system.
Does ambient air temperature sensor affect engine performance?
It is used by the heating and A/C systems. Ambient temp sensor is not going to affect the engine performance.

What is an in-cabin temperature sensor?
This means that as temperature increases, resistance in the sensor decreases. Its signal voltage varies between 0 and 5 volts. The electronic automatic temperature control system's microprocessor uses this, along with the ambient temperature and sun load sensors input to adjust cooling load, fan speed, and volume according to different temperatures and conditions.

These sensors can be located in different areas throughout the vehicle. The In-Car Temperature sensor (ICTS) is a negative temperature coefficient sensor.
What causes an air sample to pass through an aspirator?
The aspirator relies on suction from the vent system. It's this suction that causes the air sample to pass through the sensor. Also, make sure nothing is blocking the vent, typically located somewhere by the A/C control panel. Many sensors contain an electric fan that can fail, resulting in an inaccurate sample.
