Today\u2019s vehicles are infinitely more efficient than those of yesteryear. However, this did not occur by accident. Increasingly stringent emissions standards of the 1970s necessitated further review and revision of vehicle powertrain design, which ultimately resulted in the introduction of on-board diagnostics.<\/p>\n
At the moment, any late model vehicle comes equipped with numerous computer modules, designed to send and receive various signals. These signals are directed through a complicated network of circuits, and their corresponding sensors. When all operate as intended, data relayed by these sensors is interpreted and accounted for by a vehicle\u2019s operating software, in a bid to enhance combustion efficiency.<\/p>\n
However, occasionally, this flow of information does not occur as expected, meeting a roadblock of sorts along the way. One such example is foretold by diagnostic trouble code P0103, which is indicative of a mass air flow circuit fault. This code can cause a number of issues and additional symptoms and is often the source of a vehicle\u2019s check engine light.<\/p>\n
Read on to learn more about diagnostic trouble code P0103, as well as how to remedy such issues should they arise in the future.<\/p>\n
