How can I tell if my IAT sensor is faulty?
So, to make sure that the IAT sensor is the actual one to blame, a few tests need to be carried out. Testing for a faulty IAT sensor is not very difficult, and requires only a scanning tool, a multimeter, and a wire piercing probe. This process is inexpensive, and is always a good idea before going in for a replacement.
What is the color code for engine wiring?
GENERAL WIRING COLOR CODE Color Use Green or green w/yellow stripe(s) DC Grounding Conductors Black or Yellow DC Negative Conductors Red DC Positive Conductors Engine and Accessory Wiring Color Code Colour Item Use Yellow w/red strip (YR) Starting circuit Starting switch to solenoid Brown/yellow stripe (BY) or Yellow (Y) – see note
What are the different names for IAT sensors?
IAT sensors are known by various names depending on the manufacturer. Those from General Motors are called manifold air temperature (MAT) sensors, while those from Ford are called either vane air temperature (VAT), air charge temperature (ACT), or manifold charging temperature (MCT)…
Where is the crank angle sensor on a Nissan D21?
Here’s a simplified ignition system wiring diagram for the 1990, 1991, 1992, 1993, and 1994 2.4L Nissan D21 Pickup. This is Part 1 and focuses on the crank angle sensor inside the distributor. The crank angle sensor is the defacto crankshaft position sensor that the PCM uses to trigger the power transistor.

Where is the IAT located on a car?
Most vehicles have their IAT = Temp sensor located on the air intake track of the vehicle. It will have 2 wires going to a plug mounted on the air intake track or air intake manifold of most vehicles.. If you cannot find your IAT and your car is 2000+ , then it maybe built into your MAF = Mass Air Flow meter and will have 4-5 wires going to it.
What happens when I Disconnect the IAT from the MAF?
Disconnecting the IAT from the MAF should get the temperature reading back to -30 to -40°F. However, if this does not happen, it means that there could be a problem with the vehicle’s internal computer, which needs to be checked and solved by a technician.
What should I do if my IAT is not working?
Connecting the 2 IAT wires with jumper cables should change the temperature to 300 °F. If this does not happen, it might mean that the wiring or the computer is bad. Now, to test the IAT sensor with a multimeter, you should measure the resistance of the sensor.
