Where is the IAT sensor in a 93' Nissan Pickup 2.4L 4Cyl

Just thought I would add a picture.

Here is mass air flow location....

The Mass Air Flow (MAF) sensor/Intake Air Temperature (IAT) sensor is located in the air cleaner case.

The Intake Air Temperature (IAT) sensor is an integral part of the Mass Air Flow (MAF) sensor. Looks like this:

Both wires to the sensor will have to be traced to see if they are shorted or broken. One wire comes from the computer and with the key on should show 5V when grounded. the other wire returns to the computer--it should not have continuity to ground. The computer sends 5V to the IAT which is a variable resister. The return voltage tells the computer the temperature of the air. If either signal is missing,(5V outgoing or return voltage), the code will set.

try a tps throttle posistion sensor the engine is not idling fast enough with the ac on thats why it stalls if you have a manual adjustment on the throttle body speed the engine up 150-200 more rpm this should solve the problem.

Hope this help.

The Intake Air Temperature (IAT) sensor determines the air temperature inside the intake manifold. Resistance changes in response to the ambient air temperature. The sensor has a negative temperature coefficient. As the temperature of the sensor rises the resistance across the sensor decreases. This provides a signal to the PCM indicating the temperature of the incoming air charge. This sensor helps the PCM to determine spark timing and air/fuel ratio. Information from this sensor is added to the pressure sensor information to calculate the air mass being sent to the cylinders. The IAT is a two wire sensor, a 5-volt reference signal is sent to the sensor and the signal return is based upon the change in the measured resistance due to temperature.

Hope helped.

check for a broken wheel speed sensor ring or sensor it self.

Try here at AutoZone.

I suggest checking out the drive lines for dry slip joints , worn slip joints , failing "U" joints rather that a transfer case
