Delphi MAF sensors provide the engine control module (ECM) with continuous information regarding how much and how fast the air is entering the engine. This ensures optimal engine performance, increases fuel economy and reduces emissions. Delphi offers a MAF sensor with dual heated elements, which allow any platform to incorporate the MAF sensors into its air or fuel system, regardless of ducting assembly. Delphi MAF sensors feature fast response, typically less than 15 milliseconds to 90 percent of flow change, for outstanding performance over a wide range of ambient temperatures. Delphi MAF sensors also use multiple sensing elements to eliminate sensitivity to changes in supply voltage and noise on power ground lines, and feature cold sealing available to -50 degrees Celsius.
