What kind of MAF sensor does GM use?

This type of GM mass air flow (MAF) sensor is used in a lot of GM makes and models, to find out if this article applies to your specific GM (Cadillac, Chevy, Buick, GMC) vehicle, take a look at the list at the bottom of this page. Now, in case this is not the article you’re looking for, there are also 3 other GM MAF sensor test articles:

Where is the cam sensor on a Chevy?

The cam sensor (camshaft position sensor) is located inside the distributor on your Chevy (or GMC or Isuzu or Olds or Cadillac) mini-van or pick up or SUV. And as I mentioned at the beginning of the article the cam sensor test is done with a multimeter in Volts DC mode.

How to test the camshaft position sensor test?

If you need to know if this camshaft position sensor test applies to your specific 4.3L, 5.0L, 5.7L GM mini-van, pick up or SUV, take a look at the ‘Applies To:’ box on the right and scroll with the next button to see all of the applications. Contents of this tutorial: Tools Needed To Test The Cam Sensor.

What are the symptoms of a bad MAF sensor?

The symptoms of a bad mass air flow sensor include a car that is difficult to start, bad fuel economy, a rough idle, lack of power especially when accelerating and sometimes a fuel smell from the exhaust fumes. A properly functioning MAF sensor is vital for an engine to run efficiently.

This list is not all inclusive but it does contain the most common symptoms of a BAD MAF sensor are: The CHECK ENGINE LIGHT (CEL) on your instrument cluster is lit nice and bright with one of the following codes: P0101 Mass Air Flow System Performance. P0102 Mass Air Flow Low Frequency.

How can I find out if I have a mass airflow sensor?

Check your repair manual, ask at your local auto parts store, or search online for this information. Sometimes, you can identify these wires by testing them as described later. So even if you don’t have this information at hand, go ahead with the tests anyway.

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 an IAT sensor malfunction?

The most obvious symptom will be the check engine light (CEL) lit nice and bright on your instrument cluster. The second will be an IAT sensor malfunction diagnostic trouble code (DTC) stored in the PCM memory. Here are some of the specific symptoms you’ll see/have: P0112: Intake Air Temperature (IAT) Sensor Circuit Low Voltage.

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 are the colors of an O2 sensor wire?

O2 sensor wire colors MANUFACTURER SENSOR MFG 1 WIRE 2 WIRE 3 WIRE General Motors DELPHI VIOLET VIOLET VIOLET PINK BROWN BROWN

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)…
