Why are resistors connected to the IAT sensor?
This is, a resistor connected in some way to Intake Air Temperature sensor (IAT), to “fool” the ECM into “thinking” that incoming air is cold, hoping that the ECM will inject more fuel to compensate for the “colder” air. ECMs are programmed to compensate in some way when the air is colder, as colder air carries more oxygen for being denser.
Do you need to test the IAT sensor?
But first, locate the IAT sensor in your particular vehicle. If the IAT sensor in your vehicle is part of the MAF or MAP sensor, you may need to test the sensor in the vehicle while checking its resistance or voltage.
Where is the IAT sensor on a Ford Explorer?
An IAT sensor located on the air duct of a Ford Explorer. Author’s own photo. A bad intake air temperature (IAT) sensor may cause one or more of the following symptoms: lean misfire, usually in a cold engine Faulty EGR system (in some applications)
Where is the IAT sensor in the inlet manifold?
The IAT sensor will usually be fitted somewhere in the inlet ducting after the air filter box or fitted on the inlet manifold. The purpose of measuring the air temperature is to identify the density of the air. Cold air is denser than hot air and therefore more fuel has to be added to cold air than hot air in order to ensure optimal combustion.
How many wires are in an IAT sensor?
Some IAT sensors are a combined unit with a MAF sensor and will contain 5+ wires. To troubleshoot IAT Sensor error codes, unplug the IAT sensor and measure voltage across terminals from the ECU. You should see 5V otherwise the problem is elsewhere and not in the sensor.
What to do if your IAT sensor is not working?
To troubleshoot IAT Sensor error codes, unplug the IAT sensor and measure voltage across terminals from the ECU. You should see 5V otherwise the problem is elsewhere and not in the sensor. Check for continuity on the IAT sensor terminals.
How many wires are in the MAF sensor?
We only need to be concerned with three of the five wires since the other 2 belong to the intake air temperature (IAT) sensor that is part of the MAF sensor assembly. Let’s turn the page and get testing.
What does the MAF sensor on a Toyota do?
The MAF sensor’s job is to measure the amount of air entering the engine (when the engine is running) and transmit this info to your Toyota’s fuel injection computer. The computer then uses this air flow measurement, along with other sensor inputs, to inject the correct amount of fuel into the engine.
Where is the air charge temperature sensor located?

In the intake manifold on drivers side by the fuel rail. Driver side of upper intake manifold. Just behind the IAC valve. IAC is just behind the throttle body.
What’s the best way to test the IAT sensor?
Scan tool. Although you can check the IAT sensor without a scan tool, using a scan tool with Live Data capability is the fastest and easiest way to test the IAT sensor. Don’t have one? Check out my recommendation: Abe’s Scan Tool Recommendation. Wire piercing probe. This tool makes it super easy to test the voltages inside the wires.

Why is my Nissan mass air flow sensor not working?
by Dan Ferrell. The mass airflow sensor (MAF) in your Nissan vehicle measures the amount of air going into the engine. If the MAF sensor sends the wrong signal to your car’s computer–because of dirt or other contamination around its sensing elements–your engine will be fed with the wrong amount of air/fuel mixture.
Where is the fresh air sensor on a Nissan?
Park your Nissan vehicle in a safe place, with enough room for you to work around the front of the car. Open the hood. Locate the MAF sensor electrical connector. The sensor is mounted in the fresh air intake duct–close to the throttle body, fuel-injection system or air-filter housing, depending on your Nissan model.
How does the air flow sensor ( MAF ) work?
The PCM uses the air flow signal to calculate how much fuel to inject. The goal is to keep the air/fuel ratio at the optimal level. In addition, the PCM uses the air flow readings to determine the shift points of the automatic transmission. If the air flow sensor doesn’t work properly, the automatic transmission might shift differently too.
How many wires does the MAF sensor have?
If the MAF sensor has 6 wires, then this is a dead giveaway that it has the air temp sensor integrated inside.
Is the Ford mass air flow ( MAF ) sensor inside?
Ford has used a Hot-Wire type mass air flow sensor for many years that either comes with or without an internal air temperature sensor. If the MAF sensor has 6 wires, then this is a dead giveaway that it has the air temp sensor integrated inside.
How many wires does an IAT sensor have?
That IAT sensor has its own reference voltage and signal return wires, so these MAF sensors have at least five wires. Regardless of whether the MAF signal is digital or analog, a scan tool will report its reading as “grams per second” (g/s) because that’s the data used for fuel control.
How is MAF sensor related to IAT sensor?
As the MAF sensor measures air flow, it must be combined with an IAT ( Intake Air Temperature) sensor to establish air density, which can be affected by temperature, altitude and forced induction.
How is the signal on a hot wire MAF measured?
The signal on a hot wire MAF can either be analog or digital. The analog signal is measured in voltage, whereas the digital signal is a frequency, and the frequency (measured in hertz) determines the amount of air flow. To identify whether the signal is analog or digital, a scan tool can be used.
What should the MAF signal be at idle?
The scan tool will provide the MAF signal output in Hz or V combined with grams/Second. The analog signal will operate between 0V and 5V and can be measured using a voltmeter. At ignition, the signal will be 0V to 0.75V (no air flow). At idle it should be around 1V to 2V and gradually increase as you increase the RPMs.
How does a mass air flow sensor work?
The MAF sensor consists of a wire within a housing. At the front of this housing a coarse grained mesh is fitted to smooth out the airflow, so that a stable reading can done by the MAF sensor. The wire is heated to a either a constant voltage over the wire or a constant current through the wire.
