Keep your engine's air-fuel calculations on target with the Delphi Mass Air Flow Sensor AF10058. This mass air flow sensor drops in as a direct-fit replacement across a wide range of GM, Hyundai and Kia applications, including the 2005-2009 Buick LaCrosse, 2004-2012 Chevrolet Malibu, 2007-2009 Chevrolet Tahoe, 2006-2010 Hyundai Sonata and 2006-2012 Kia Sedona — 63 applications in all, so see the Buyer's Guide tab for the full list.
- Measures intake airflow: Reports the mass of air entering the engine so the powertrain control module can calculate the correct amount of fuel to inject.
- Supports normal running: An accurate airflow signal helps the engine maintain proper idle, throttle response and fuel metering.
- Direct-fit replacement: Installs in place of the original mass air flow sensor on the listed applications.
The mass air flow sensor sits in the intake tract between the air filter and the throttle. When the original sensor drifts or fails, the ECM can miscalculate fuel delivery, which may show up as rough idle, hesitation, stalling, reduced fuel economy or a check engine light. Because these signs can have other causes, diagnose the fault first; if a failed MAF sensor is confirmed, this AF10058 replaces it.
Interchange: Manufacturer part number AF10058.
Frequently Asked Questions
What does this mass air flow sensor do?
It measures the mass of air entering the engine and sends that signal to the powertrain control module, which uses it to calculate the correct amount of fuel to inject.
Will the Delphi AF10058 fit my vehicle?
It is a direct-fit replacement for 63 GM, Hyundai and Kia applications, such as the 2004-2012 Chevrolet Malibu and 2006-2010 Hyundai Sonata. Check the Buyer's Guide tab for the full list.
What are the signs a mass air flow sensor may need replacing?
Possible signs include rough idle, hesitation, stalling, reduced fuel economy or a check engine light. These symptoms can have other causes, so diagnose the fault before replacing.
Where is the mass air flow sensor located?
It sits in the intake tract between the air filter and the throttle, where it can read the air flowing into the engine.
Should I diagnose before replacing the sensor?
Yes. Because the symptoms of a bad MAF sensor overlap with other issues, confirm the sensor is the cause first; if it is, the AF10058 replaces the original unit.
