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.
