A-Premium MAP Sensor for GM Vehicles — Direct-Fit 3-Terminal Black Housing, OEM-Style Replacement

The A-Premium Manifold Absolute Pressure (MAP) sensor is a direct-fit, three-terminal replacement designed to restore accurate intake pressure readings on many Chevrolet, GMC, Buick and Cadillac vehicles from the mid-1990s through the late 2000s.

When your vehicle relies on precise manifold pressure information for fuel delivery and engine management, a reliable MAP sensor is essential. This A-Premium unit matches OEM electrical and mounting characteristics — black oval housing, female connector with three blade terminals — and fits a long list of GM models. It ships with a one-year unlimited-mileage guarantee for added confidence.

Which vehicles will this MAP sensor fit?

This sensor covers an extensive range of General Motors applications across Chevrolet, GMC, Buick and Cadillac lines. Compatibility lists include popular trucks, SUVs and sedans from model years roughly 1995–2011, including many Silverado, Suburban, Tahoe, Camaro, Impala and Escalade variants.

• Chevrolet: Silverado, Suburban, Tahoe, Camaro, Impala, S10, Avalanche and more (1995–2008 ranges depending on model).
• GMC: Sierra, Yukon and pickup/SUV platforms across late 1990s–2008 model years.
• Buick & Cadillac: LaCrosse, LeSabre, Lucerne, Seville, DTS, Escalade families among compatible years.

How does this A-Premium MAP sensor compare to the original equipment part?

The A-Premium sensor is built to mirror the OEM form, fit and electrical interface so it installs without modification. It uses the same oval body shape and a three-blade, female connector layout, allowing the vehicle harness to plug in directly and maintain correct signal routing to the engine control module.

• Connector: female oval plug with three blade terminals, matching factory harnesses.
• Finish and color: black housing for a factory-look installation.
• Reference numbers: cross-references include AS59, 12614973, 16187556 and other OEM part IDs.

What should I expect during installation and setup?

Installation is straightforward for typical in-line MAP sensors: disconnect the battery, unplug the electrical connector, unfasten mounting hardware, swap the sensor and reverse the steps. No special programming is generally required; the vehicle's ECU recognizes the sensor through its standard wiring and resumes normal operation once reconnected.

• Tools: basic hand tools for removing mounting screws or bolts.
• Time: most installations take 15–30 minutes for experienced DIYers.
• Post-installation: clear codes if present and check for proper idle and drivability; no module reflash usually needed.

What are the technical details and warranty coverage?

This MAP sensor arrives with defined electrical and mechanical specifications to match factory expectations: a three-terminal female connector, oval-shaped housing and a durable black finish. A-Premium backs the part with a one-year unlimited-mileage guarantee to protect against manufacturing defects.

• Terminal count: 3 blade terminals, female connector geometry.
• Color/finish: black housing for corrosion resistance and OEM appearance.
• Warranty: one-year unlimited-mileage guarantee from A-Premium.

Who is this for? If you own a compatible Chevrolet, GMC, Buick or Cadillac from the covered model years and you need a cost-effective replacement for a failing MAP sensor, this A-Premium unit is engineered as a direct-fit alternative to restore intake pressure sensing. It’s suitable for DIY mechanics and professional installers who want a part that mirrors OEM connectors and mounting while offering aftermarket value and warranty protection.
