This part cross-references Standard Ignition MAS0133 and Delphi AF10134 for the same application.

What It Is Used For

• Correcting inaccurate airflow readings that can affect fuel trim
• Addressing rough idle or hesitation tied to sensor signal issues
• Restoring drivability when the engine control system receives faulty air data
• Replacing a worn or contaminated mass air flow sensor
• Supporting emission control performance when sensor output is out of range

Installation Notes and Tips

Install the sensor only on applications listed in the fitment data for MG0019. Verify the connector style, housing configuration, and any application notes before installation. After replacement, clear diagnostic trouble codes and confirm that the engine runs smoothly at idle and under load.
