Detailed Description

Standard Ignition MAS0201 is engineered to help the engine control unit receive precise airflow data so it can maintain the correct air/fuel ratio. The sensor uses high-quality sensing elements that hold up to supply-voltage changes and harsh operating temperatures from -40°F to 257°F. For drivers searching for a mass air flow sensor for 1996-2005 Chevrolet Blazer, 1996-2005 GMC Jimmy, or 1994-2003 Pontiac Grand Prix, this part provides a direct replacement solution with the correct connector style and mounting layout.

This part cross-references Delphi AF10055 and Walker Products 245-1062 for the same application. Standard Ignition MAS0201 also serves as an OE-style replacement for many other listed vehicles across the 1994-2005 model years.

What It Helps Resolve

• Rough idle caused by inaccurate airflow readings
• Hesitation or stumble during acceleration
• Check engine light related to airflow sensor performance
• Poor fuel economy from incorrect air/fuel mixture control
• Hard starting or unstable engine operation under load

Installation Notes and Tips

Verify connector shape, terminal count, and bolt-on mounting before installation. This sensor uses a female oval connector with 3 male blade terminals and 2 bolt holes, so matching the original housing and electrical connection is important for proper fitment. Clean the intake tract and inspect the air filter system before installing the new sensor to help prevent contamination of the sensing elements.
