The ambient air sensor detects the temperature and quality of the outside air, allowing the vehicle's air conditioning (AC) system to adjust its operation accordingly. If the sensor detects high temperatures or poor air quality, the AC may work harder to cool and filter the incoming air. Conversely, in cooler or cleaner conditions, the system can reduce energy usage by minimizing cooling efforts. This sensor helps optimize cabin comfort while enhancing energy efficiency.
It can, yes. If the ambient air temperature is registering as too cold, the sensor bulb will prevent the AC from engaging.
P0071=Ambient Air Temperature Sensor Range/Performance. There is a temp sensor in the fresh air intake that monitors the ambient air temp coming into the engine. Check to see if it is disconnected. On this van, the ambient temperature sensor is located in front of the bottom of the ac condenser.
It is behind the front bumper fascia, clipped on the bottom of the ac condenser.
open glovebox..remove plastic behind glove box..phillips head screwdriver..its on the ac cannister
Check your ambient temperature sensor located behind the front grill. Also if you are getting false temp. readings on your dash or it is stuck at fifty degrees, then it is definitly your sensor.
The AC system doesn't use water. Water may be produced at the evaporator as a result of the rapid exchange of heat to the ambient air, but there is no water in an AC system.
The AC compressor uses a chemical refrigerant known as freon to cool air as it comes into the cabin of your car. This chemical can leak out over time and as it leaks, it turns to gas, so you can't see it leaking out. If you turn on the ac and just ambient air comes in, you can your Air conditioning recharged, and see if anything improves.
The average ambient pressure range for automotive air conditioning systems is between 30 psi and 230 psi. This is based on an ambient temperature of 90 degrees Fahrenheit or less.
No it does not affect air flow. The air will just not be as cool.
No. The dessicant will become saturated within five minutes of exposure to ambient air, and the whole thing must be replaced.
It varies between AC systems, and also which type. Automatic Temperature Control systems won't even turn the blower motor on if the ambient air temperature is too cold. Non ATC/SATC systems will run the blower motor, but the sensor bulbs will disengage the compressor clutch, preventing the refrigerant from cycling.
there are a few sensors. One is built into the Air Flow Meter. That sensor is for engine controls. A second sits in front of the radiator I believe and is used for the AC. The third site in the dash somewhere and is used for the AC. The in car temp sensor is in the center console behind the armrest compartment.
