Detailed Description

The MAS0222 is built to deliver stable airflow data under demanding engine conditions, helping the ECU maintain the correct air/fuel balance for cleaner combustion. Standard Ignition manufactures this sensor to strict quality standards and subjects it to durability and environmental testing for consistent performance in harsh driving environments. This part cross-references Delphi AF10138 for the same application.

What It Helps Address

  • Rough idle caused by inaccurate airflow readings
  • Check engine light concerns related to the mass air flow circuit
  • Hesitation or poor throttle response from incorrect air metering
  • Fuel trim issues tied to an unsteady MAF signal
  • Driveability problems on 1995-1999 Oldsmobile Aurora and 1996-1999 Cadillac DeVille, Eldorado, and Seville models

Installation Notes and Tips

Compatible With 1996-1999 Cadillac DeVille, 1996-1999 Cadillac Eldorado, 1996-1999 Cadillac Seville, and 1995-1999 Oldsmobile Aurora. Verify the oval 1-connector, 3-terminal blade configuration and 2-bolt mounting pattern before installation. Transfer any required intake components separately, since the housing is not included. The part number MAS0222 should be matched to the original sensor specification before replacement.

Quality Assurance

Standard Ignition builds this MAS0222 sensor as a new replacement part and computer-tests each unit for airflow accuracy. It also undergoes durability and environmental testing to support reliable operation in demanding conditions.
