MAF sensors

Delphi has added 20 new mass airflow sensors to its engine management portfolio covering more than 10.2 million vehicles built from 1990 to 2013.

Applications cover: Audi, BMW, Chevrolet, Hyundai, Kia, Lexus, Mazda, Nissan and Toyota.

Part numbers include: AF10159, AF10162, AF10164, AF10168, AF10176, AF10184, AF10185, AF10205, AF10206, AF10207, AF10208, AF10210, AF10211, AF10212, AF10213, AF10215, AF10216, AF10217, AF10219 and AF10220.

Inventory is available dependent on part number to end of Q2 2014.

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 Delphi oxygen sensors, the engine’s air/fuel ratio can be controlled much more accurately. All of these functions ensure accurate air/fuel ratio for optimal engine performance in any driving condition.

Contamination is a key reason why MAF sensors fail and require replacement. As air, dirt and other debris get into the sensor, the parts become contaminated and result in failure. Drivers often notice sluggish performance or a more frequent need to refuel.

Delphi says its MAF sensors are brand-new, never remanufactured. All parts are tested and calibrated to OE standards using highly accurate OE equipment. By testing to OE specifications, Delphi ensures that the sensors provide accurate readings and airflow output, which helps to reduce comebacks.

Delphi’s direct sensor solution design allows technicians to focus on the part that needs to be replaced. Most of the time it is the sensing electronics in the probe that fail. By eliminating the need to replace the plastic flow tube, Delphi provides a greener repair solution.

Shops receive Delphi Mass Airflow sensors in a plastic clamshell, which helps protect the sensing elements from damage.
