Delphi Announces Mass Air Flow (MAF) Sensors to its Engine Management Portfolio

Delphi announces three new MAF sensors to its engine management portfolio covering more than 780,000 Ford, Chrysler, Saturn, Volvo and GM vehicles from 2004 to 2011. Part numbers:  AF10138, AF10139 and AF10143. 


Delphi announces three new MAF sensors to its engine management portfolio covering more than 780,000 Ford, Chrysler, Saturn, Volvo and GM vehicles from 2004 to 2011. Part numbers:  AF10138, AF10139 and AF10143. 

Inventory will be available Q4 2012.

Unlike offerings from many competitors, Delphi MAF sensors are built with all-new components; not remanufactured parts. All parts are tested and calibrated to OE standards using OE equipment in U.S. facilities.

Delphi’s design eliminates the need for an additional flow tube, helping shops reduce inventory and shelf space and eliminate the hassle of remanufactured cores.

Shops receive Delphi Mass airflow sensors in a plastic clamshell, which helps protect the sensing elements from damage. All Delphi MAF sensors come with a drill bit and tamper-proof screws to assist with installation.

MAF sensors measure intake airflow and send this information to the ECU. When the ECU receives the information from the MAF sensor and oxygen sensors, it makes adjustments to the amount of fuel being injected into the engine to compensate for excess air or excess fuel. When a Delphi MAF sensor is used in combination with a Delphi oxygen sensor, the engine’s air/fuel ratio can be controlled much more accurately.
