Keep the engine's air-fuel calculations accurate with the Standard Ignition Mass Air Flow Sensor MAS0515. It installs as a direct-fit replacement for the 2009-2011 Hyundai Azera and the 2012-2013 Hyundai Equus, measuring the air entering the engine so the powertrain control module can meter the correct amount of fuel.
- Core function: Reads the intake air flowing to the engine and sends that signal to the ECU, which uses it to help set fuel delivery.
- Direct-fit design: Built to replace the mass air flow sensor on the listed applications.
- Signs it may need replacing: Rough or uneven idle, hesitation, poor fuel economy, or a stored air-flow-related trouble code can point to a sensor issue.
A mass air flow sensor can drift or fail over time as contamination builds on the sensing element. If a faulty air flow sensor is the cause of your driveability complaint, replacing it with MAS0515 restores the correct signal to the control module. Because these symptoms can have other causes, diagnose the fault before replacing the part.
Manufacturer part number MAS0515.
