Standard Ignition MAS0229 mass air flow sensor for the 2004-2009 Ford F-150 V8 4.6L and other vehicles measures the air entering the engine and reports it to the ECU. The ECU uses that reading to balance the air/fuel ratio.
- 100% computer-tested so the ECU receives accurate airflow readings under hard engine conditions
- New part with no leftover debris that can cause sensor failure
- Designed to improve engine performance, reduce harmful emissions and increase fuel efficiency
- Manufactured and calibrated to strict quality standards
Quick facts
- Part: Standard Ignition MAS0229 mass air flow sensor
- Fits: 2004-2009 Ford F-150 V8 4.6L and other vehicles
- Material: Metal
- Condition: New
A failing mass air flow sensor can show up as a rough idle, hesitation or a check engine light. These signs alone do not prove the sensor is the problem, since a vacuum leak in the intake can cause similar symptoms.
Fits
The 2004-2009 Ford F-150 V8 4.6L, the 2002-2005 Ford Explorer V8 4.6L and the 2003-2004 Ford Mustang V8 4.6L are among the many vehicles this mass air flow sensor fits. It is a direct-fit OE replacement, tested to OE specifications. Open the "Vehicles it fits" section to check your exact model and engine.

Frequently Asked Questions
Does the Standard Ignition MAS0229 work as a mass air flow sensor for the 2004-2009 Ford F-150 V8 4.6L?
Yes. Standard Ignition MAS0229 fits the 2004-2009 Ford F-150 V8 4.6L. For other years or engines, open the "Vehicles it fits" section.
Is this a mass air flow sensor for the 2003-2004 Ford Mustang V8 4.6L?
Yes. Standard Ignition MAS0229 fits the 2003-2004 Ford Mustang V8 4.6L, and that car takes one sensor.
How does the Standard Ignition MAS0229 mass air flow sensor mount and connect?
This sensor bolts on through 4 bolt holes and plugs in through one rectangular female connector. The connector has 6 male blade terminals.
How is this mass air flow sensor tested before it is sold?
Each unit is 100% computer-tested to confirm the ECU receives accurate airflow readings under hard engine conditions. It is also calibrated to strict quality standards.
Can a bad mass air flow sensor cause hesitation or a rough idle?
Yes, a failing mass air flow sensor can be one cause, since the ECU relies on the airflow reading to set the air/fuel ratio. A shop can test the sensor's readings.
