Where are the IAT sensor wires on a 1990 Nissan Hardbody 3.0L? Are they part of the MAF sensor or separate? Can you provide the location diagram and the specific IAT colors?Thanks.

Greetings From Arench!The service manual does not show an air temp sensor. There are not enough wires going to the air flow meter so it is not there.I pulled up the engine computer diagram and looked at every wire and there is no mention of an ambient air temp sensor.The only places an air temperature sensor would be is the air filter housing or the air tube.Next I looked at the list of diagnostic trouble codes that this ECU can flash out and there is no code for air temperature sensor circuit.Based on the information missing from the component locater, lack of appearance in the wiring diagram, lack of fault code for the circuit I would have to say this vehicle is not equipped with an ambient air temp sensor.Arench41108.0090083681
