Where does the ambient air temperature sensor connect?
Where does the ambient air temperature sensor connect?
The ambient air temperature sensor connector attaches the sensor to the wiring needed to connect to the control unit for the heating, ventilation, and air conditioning (HVAC) system to keep from putting additional stress on the system in especially hot or cold climates. The connector also attaches the sensor to the ECU to display…
What is the resistance of the ambient temperature sensor?
Turn the ignition switch to the Off position. Disconnect the ambient temperature sensor wire harness connector. Measure the resistance of the ambient temperature sensor. At –40° C (–40° F), the sensor resistance is 336.6 K ohms. At 60° C (140° F), the sensor resistance is 2.49 K ohms. The sensor resistance should read between these two values.
When to worry about outside ambient temperature sensor?
They probably want some air flowing past the sensor after sitting in front of a hot engine to get the correct temperature before showing the temperature on the display. Bottom line don’t worry about the temperature accuracy until you have gone 20MPH + for at least 3 consectuive minutes.
Where is the ambient temperature sensor on a jeep?
Below is a summary – the technical good stuff was posted by a Jeep tech in the UK. First the location of the sensor – just behind the right most section of the grill – see pictures attached. To remove it you can reach under the front fender and grab the assembly – twist and pull it slightly to the rear and it will come loose.

Where is the air temperature sensor on a Honda Accord?
Step 2: Locate the sensor. You can find the ambient air temperature sensor at the front of the engine bay. Usually, this sensor is located behind the grille but is in front of the radiator and radiator support.
