He decided to replace this with a modern mass air flow (MAF) sensor instead, and documented the process online.

Check to see if these wires have 12 volts at the mass air flow sensor using a multimeter. This voltage will only be applied for approximately 5 to 30 seconds after the engine has been shut off ...

Usually, the mass air flow sensor is positioned between the intake manifold and the air filter. The primary function of this part is to measure the amount and density of air entering the engine.

GM has issued a recall for certain units of the Chevy Low Cab Forward 3500 and 4500 models due to an issue with the mass air flow (MAF) sensor.

And if your car's check-engine light is giving you the side-eye, it helps to know about other sensors, too, like the Mass Air Flow sensor and when it goes bad.

This sensor type is based on the principle that if a mass is maintained at a constant temperature (above ambient air temp), the thermal loss is proportional to the flow of air over that mass.
