This is not a direct answer.
The ambient temp sensor location is different from car to car based on Make Model year and engine.
This sensor is located to measure the air temperature so the engine injection, anti-lock brakes, transmission shift and safety features all work.
On most Pontiac Fieros this sensor is mounted on the air cleaner and is called the "intake air temp sensor"
On many Dodge pick up trucks it is mounted in front of the radiator.
The airflow ambient temperature sensor is located on the air intake housing. The sensor should be labeled as the airflow ambient temperature sensor.
were is the location of the ambient air temperature sensor for a 2001 bmw 330 i
The ambient air temperature sensor, on your Nissan automobile, is located in the drivers side mirror. The sensor is on the bottom of the mirror.
I posted pictures on the location and replacement of an ambient temp. sensor for a 2001 S40. Google "ambient temperature sensor location/replacement" or go to Matthew's Volvo site and search there.
Tamb (K): sensor (ambient) temperature (Kelvin)
The ambient temperature sensor is located behind the front grill.
On the 2000 town car, the ambient temperature sensor is under the hood. More precisely, behind the grill mounted to the upper radiator support.
The Ambient air temperature is monitored by the Electronic Vehicle Information Center (EVIC) through ambient temperature messages received from the Body Control Module (BCM) over the Programmable Communications Interface (PCI) data bus network. The BCM receives a hard wired input from the ambient temperature sensor. The ambient temperature sensor is a variable resistor mounted to a bracket that is secured with a screw to the right side of the headlamp mounting module grille opening, behind the radiator grille and in front of the engine compartment. The ambient temperature sensor cannot be adjusted or repaired and, if faulty or damaged, it must be replaced.OPERATIONThe ambient temperature sensor is a variable resistor that operates on a five-volt reference signal sent to it by the BCM. The resistance in the sensor changes as temperature changes, changing the temperature sensor signal circuit voltage to the BCM. Based upon the resistance in the sensor, the BCM senses a specific voltage on the temperature sensor signal circuit, which it is programmed to correspond to a specific temperature. The BCM then sends the proper ambient temperature messages to the EVIC over the PCI data bus.The temperature function is supported by the ambient temperature sensor, a wiring circuit, the Body Control Module (BCM), the Programmable Communications Interface (PCI) data bus, and a portion of the Electronic Vehicle Information Center (EVIC) module. If any portion of the ambient temperature sensor circuit fails, the BCM will self-diagnose the circuit. A temperature reading of 130° F will appear in the EVIC display in place of the temperature when the sensor circuit is shorted. A temperature reading of -40° F will appear in the EVIC display in place of the temperature when the sensor circuit is open.
If you are reading a code with the description "ambient temp. sensor open" that means that the sensor or the wiring to the sensor is open or broken. The sensor will have to be replaced or the wiring to the sensor repaired. Have it troubleshot prior to just throwing parts at it.
P1942 Transmission adaptation, On a Dodge Durango the ambient temperature sensor is used by the DPLV, heated oxygen sensor circuit and a transmission fluid temperature sensor , If the ambient temperature is not rational in regards to the engine temperature sensor the transmission temperature will adapt to a substituted temperature value, this in turn will effect the 2-3 shift points on the transmission,
It monitors the atmospheric (outside) temperature.
The ambient air temperature sensor, on a Caterpillar see 13 diesel engine, is located between the air filter and the air intake on the engine. The sensor should be near the air filter.
