MAF sensors

Delphi has introduced five new mass airflow sensors that cover nearly 1 million vehicles built from 1990 to 2013. Applications cover manufacturers including Nissan, Audi, Toyota, and Infiniti.

Part numbers: AF10198, AF10209, AF10214, AF10218 and AF10221.

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.

Delphi says when one of its 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.

Unlike offerings from many competitors, 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 allows technicians to focus on the part that needs to be replaced. 98% 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.
