How to test the intake air temperature ( IAT ) sensor?

Testing the intake air temperature (IAT) sensor, which is located inside the mass air flow (MAF) sensor, can easily be done with a scan tool and/or a multimeter. In this article, I’ll show you how to test IAT sensor in a step-by-step way that will help you say that, ‘Yes, it’s BAD’ or ‘No, it’s not BAD’.

What are the symptoms of a bad MAF sensor?

Here are the most common symptoms of a bad or failing MAF sensor: Idle Issues – Your Impala may run rich or lean when idling, or it may also idle erratically. A rich condition is when there is not enough air relative to the fuel in the air/fuel mixture.

How does the IAT sensor help the PCM?

With the IAT sensor, it get’s to know the temperature of that incoming air and then is able to better calculate how dense that air is. Calculating the flow rate and density of the air that the engine is breathing at any given time helps the PCM maximize everything from fuel consumption to performance.

What happens if your MAF sensor is bad?

The mass airflow sensor (commonly abbreviated to MAF) is one of the most important engine management sensors. A bad mass airflow sensor can leave your Chevy Impala’s engine running rough, or even inoperable. A MAF sensor measures the density of the air entering the intake manifold.

Where is the MAF sensor on a Chevy Cruze?

Uses mass airflow sensor cleaner. It’s really cheap and available at any parts store. It sure beats the heck out of having to buy a new sensor. Locate the MAF Sensor – It’ll be in between the air filter and the throttle body.

Where is the mass air flow sensor on a Chevy?

In this guide, you will learn about Chevy Mass Air Flow (MAF) sensor problems, common symptoms, and how to replace the MAF sensor on a Chevy. The engine control unit uses data from the MAF sensor to calculate the correct mixture of air and fuel that the engine needs. A Chevy MAF sensor is located right next to the engine air filter housing.

How to replace a mass airflow sensor in a car?

In most vehicle models, all you have to do is: 1 Disconnect the part of the air intake duct that connects to the MAF sensor. 2 Carefully unplug the sensor electrical connector. 3 Unscrew two or more sensor mounting bolts. 4 Remove the old sensor. 5 Install the new one.

How do you reset the TPMs on a Chevy Impala?

1. Turn ignition to the ACC position. 2. Press and hold unlock and lock buttons on the keyless entry transmitter until horn sounds and left turn signal is illuminated. Or using the DIC, press and release INFO button until TIRE LEARN message is indicated on display. Hold down SET/RESET button until horn sounds and left turn signal is illuminated. 3.

How to learn PassLock sensor data code for Chevrolet Impala?

Start the engine (the vehicle has now learned the Passlock Sensor Data Code and/or password). With a scan tool, clear any DTCs if needed (history DTCs will self clear after 100 ignition cycles).

Is the IAT built into the MAF sensor?

On some module with a mass air flow (MAF) sensor, the IAT is incorporated into the same housing On some models with a manifold absolute pressure (MAP) sensor, the IAT is built into the sensor as well. If necessary, consult your vehicle repair manual to locate the sensor. III. Different Names for the IAT Sensor

What are the trouble codes for the MAP sensor?

On most OBD1 applications, there are two trouble codes associated with the MAP sensor. A code 33 will set if the MAP sensor output voltage is higher than expected (indicating low vacuum) and a code 34 will set if the MAP sensor output voltage is lower than expected (indicating high vacuum).

How to test the GM MAF sensor in Spanish?

Now, in case this is not the article you’re looking for, there are also 3 other GM MAF sensor test articles: You can find this tutorial in Spanish here: Cómo Probar El Sensor MAF GM 3.1L, 3.4L, 4.3L, 5.0L, y 5.7L (at: autotecnico-online.com ).

What is the MAF signal at 2500 rpm?

At 2500 RPM it hovers around 4.2 K Hz. The important thing to know, is that the more air the engine breathes (or the higher the RPM) the higher the MAF Hertz signal becomes, and of course the less air the engine breathes, the lower the Hertz signal (that your digital multimeter will record).
