2019 Infiniti M35 V6-3.5L (VQ35HR) Diagnostic and Repair Information Page 250
The intake air temperature sensor is built-into the mass air flow sensor (1). The sensor detects intake air temperature and transmits a signal to the
ECM.
The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. Electrical resistance of the thermistor decreases in
response to the rise in temperature.
NOTE:
ECM uses only the intake air temperature sensor (bank 1) for engine control and self-diagnosis. It does not use the intake air temperature sensor
(bank 2).
