Delphi MAF Sensors:
Always New, Never Remanufactured
Some Things are Better New.
That’s why every mass airflow sensor we make—whether with or without the housing—is built with calibrated all-new components and is never remanufactured. our MAF 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.
About MAF Sensors
A Mass Airflow (MAF) 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 MAF sensor 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 MAF sensor designs provide low restriction air measurement for increased horsepower.
MAF sensors 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 MAF Sensors Fail?
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 fail. Drivers often notice sluggish performance, rough idling or even stalling. There may also be a more frequent need to refuel.
The Benefits are Clear
You won’t find any remanufactured MAF sensors in a Delphi box. Even better, all parts are tested and calibrated to OE standards using highly accurate OE equipment. By testing to OE specifications, Delphi helps ensure that the sensors provide accurate readings and airflow output, which helps to reduce comebacks.
Remember, many remanufactured MAFs 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 MAF sensors feature dual heated elements, allowing any platform to incorporate our MAF sensors into its air/ fuel system, regardless of ducting assembly.
Shops receive Delphi MAF sensors in a plastic clamshell, which helps protect the sensing elements from damage. Delphi MAF 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: Delphi MAF Sensor Probe-Only Technology
Delphi 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 is providing a greener, more cost-effective approach to repair.
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
