Ambient Sensor
WARNING: This page is about a different car, the 2019 Nissan NV3500 HD, 2019 Nissan NV2500 HD, and 2019 Nissan NV1500. However, it is still accessible from the selected car via links, so may be relevant.
- The ambient sensor is installed behind the grill, in front of the radiator, on the center core support.
- The ambient sensor is a thermistor. The resistance of the sensor changes with temperature, and the front air control converts this analog data into a digital count, ranging from 10 to 95 AD (Analog to Digital) counts. Data is transmitted on the CAN in AD counts, but always reported in deg. C. A conversion algorithm is used to convert deg. C to deg. F. The range of the sensor is from -30 deg. C (-22 deg. F) to 55 deg. C (131 deg. F).
