Chrysler 300 Mass Air Flow Sensors & Components

A mass air flow (MAF) sensor is a part of an electronic fuel injection system. Its job is to measure the volume of air coming to the engine . There are several types of MAF sensors, but most of modern automobiles utilize a hot-wire type. These sensors have an electrically heated wire and a temperature sensor that is installed close to it. A temperature sensor defines the temperature of air near the wire. The air temperature changes depending on the amount of air that goes pass the wire. Correspondingly, it takes different amounts of current to keep the wire hot. According to the changing amounts of current, your vehicle’s PCM receives respective signals concerning the air flow volume and can adjust the volume of fuel delivered to the engine.

MAF sensor problems are often misdiagnosed on the Chrysler 300. Prior to replacing the MAF sensor, check the connecting air ducts and intake manifold for air leaks, since they can cause similar symptoms to those of a malfunctioning mass air flow sensor. If your automobile utilizes a MAF sensor with a sense wire, the wire can get contaminated with dust. A contaminated sensor will not be able to correctly measure the volume of air flow, leading to such drivability problems as a no-start, stalling, and poor acceleration.
