Mass Air Flow Sensors

Always new, never remanufactured MAF sensors

That’s why every mass airflow sensor (MAF sensor)  we make—whether with or without the housing—is built with calibrated all-new components and is never remanufactured. Our mass air flow sensors are designed and tested to meet or exceed OE requirements, and engineered for a perfect fit in more than 145 million vehicles on the road today in North America — including makes from Ford, Toyota, Nissan, Volkswagen, Hyundai, BMW, Honda, GM, Mazda, Subaru, Acura and more.

The Delphi Difference
First OE manufacturer to create an all-new, all-makes replacement option
Offering a greener, quicker probe-only repair alternative
Golf ball dimples on select models
Innovative, multiple sensing elements
Calibrated to OE specifications to reduce comebacks

The OE benefits are clear

You won’t find any remanufactured MAF sensors in a Delphi Technologies box. Even better, all parts are tested and calibrated to OE standards using highly accurate OE equipment. By testing to OE specifications, Delphi Technologies helps ensure that the sensors provide accurate readings and airflow output, which helps to reduce comebacks.

Remember, many remanufactured sensors are simply cleaned and tested, so all debris or contamination on the sensor may not be completely eliminated. Because of this, the ECM could still receive inaccurate readings and the vehicle may still experience sluggish performance. 

Certain Delphi Technologies sensors feature dual heated elements, allowing any platform to incorporate our sensors into its air/ fuel system, regardless of ducting assembly. 

Shops receive them in a plastic clamshell, which helps protect the sensing elements from damage. Delphi Technologies mass air flow sensors come with a driver bit and screws to assist with installation. Look for clamshell packaging sealed with a factory sticker, which indicates it is direct from the manufacturer and has not been touched or damaged in transit.

Greener and less costly

em_maf_greenDelphi Technologies MAF sensor probe-only technology

Delphi Technologies offers a MAF sensor probe as a greener, less costly alternative to the traditional MAF assembly repair. This option allows technicians to focus on the part that needs replacement. 

In most cases it's unnecessary to replace the complete part since it‘s the electronics on the sensor probe that fail 98% of the time.

By eliminating the need to replace the plastic housing, Delphi Technologies is providing a greener, more cost-effective approach to repair. 

About MAF sensors

A Mass Airflow sensor also known as an “air meter,” measures the air coming into the intake system and transmits this information to the ECM. The ECM utilizes the output signal to precisely schedule fuel injection, creating an optimal air-fuel ratio. This results in reduced emissions and improved fuel economy, all while maintaining drivability. Delphi Technologies mass air flow sensor designs provide low restriction air measurement for increased horsepower.

It can be installed two ways: as a complete unit including the flow tube or as a probe-only design, which provides a greener, more cost-effective and often faster option. 

Why do mass air flow sensors fail?

Contamination is a key reason why they fail and require replacement. As air, dirt and other debris get into the sensor, the parts become contaminated and fail. Drivers often notice sluggish performance, rough idling or even stalling. There may also be a more frequent need to refuel.
