Modern vehicles rely on a massive amount of electrical systems, sensors, and control modules to keep the wheels turning. Some of those devices are well-known, like your car's main computer or engine ...

Imagine a turbocharger trying to pressurize a carburetor with its small venturis and finicky floats and you can get some idea why electronic fuel injection opened the door to big boost, big power, big ...

A mass air flow sensor is one of the numerous tiny widgets and gewgaws that make up a modern automobile's electronic fuel injection system. In the MAF's case, it tells the car's computer how much air ...

Q:I have a 1996 Corvette that gave me a recurring fault code (P0171 - "System Too Lean, Bank One") for more than a year. The code reader on my scanner indicated that the fuel pump was defective, so I ...

Electronic fuel injection was a big leap forward for engine control. However, early implementations often left something to be desired. This was the case for [Rob] and his Porsche 944, which had ...

A device in the throttle body, the mass airflow, or MAF, sensor helps the engine computer determine the proper air-fuel mixture by measuring the mass of the air flowing past it. Because a precise ...

Your engine needs a steady stream of clean air to function properly, and it's the job of the mass air flow (MAF) sensor to measure and regulate the amount of clean air entering the intake. The engine ...
