A-Premium Mass Air Flow Sensor Assembly 3‑Pin Direct-Fit for Chevy & GMC — OE-Style Durable

A-Premium 3-pin Mass Air Flow (MAF) Sensor Assembly accurately measures intake air for compatible Chevrolet, GMC and related V8/V6 models from the mid-1990s to early 2000s.

This replacement MAF sensor is a direct-fit, bolt-on assembly designed to restore correct air-measurement to engines that originally used a 3-terminal flow sensor. Built from reinforced PBT plastic and aluminum alloy components, the unit matches OE mounting and electrical interfaces for many Chevrolet, GMC, Cadillac, Pontiac and related vehicles. The part is sold with a one-year unlimited-mileage A-Premium warranty for confidence at installation.

Which vehicles will this A-Premium MAF sensor fit?

Compatibility covers a broad set of late-1990s and early-2000s GM models with 3-pin MAF requirements. Always compare the listed reference numbers and connector style to your original sensor before purchasing to ensure a correct match.

• Chevrolet models: C1500, C2500, C3500, Camaro, Corvette, Express, Tahoe, Suburban (various V8/V6 engines, 1993–2002 ranges).
• GMC models: C/K-series trucks, Yukon, Savana, P-series vans (multiple V8/V6 fits, 1996–2002).
• Also compatible with Cadillac Escalade (1999–2000) and Pontiac Firebird (1993–2002) where 3-pin MAFs were used.
• Reference numbers included for cross-checking: 19112572, 25179711, 25008307, AF10056, SK2451067 and others.

How accurate and durable is the sensor for daily driving?

This MAF assembly is engineered to maintain stable measurements across typical automotive conditions, with a stated measuring range and tight accuracy. Materials and mounting match OE expectations to reduce intermittent failures and extend service life under normal use.

• Measuring range: 0–9.25 m³/min with ±3% accuracy under specified conditions.
• Construction: PBT plastic reinforced with fiberglass and aluminum alloy elements for thermal stability.
• Electrical: 3-pin female connector, blade-style terminals, 12 V supply compatibility.
• Mounting: Bolt-on fit with four bolt holes to align with factory flanges.

What should I check before installing this replacement MAF?

Confirm connector gender, terminal count and mounting pattern match your original sensor. Inspect hose fittings and intake tubing for cracks or leaks that could affect readings; replacing the MAF alone will not correct vacuum or air-leak issues.

• Verify 3-terminal configuration and female connector on the vehicle harness.
• Compare bolt-hole pattern and physical dimensions to original part.
• Cross-check listed reference numbers against your OEM part number for exact replacement.
• Clean intake tubing/clamps and replace air filter if contaminated before testing operation.

Will this A-Premium unit work with my vehicle’s ECU without programming?

As a direct-fit passive MAF sensor assembly, it is designed to interface with factory ECUs that accept the same 3-pin signal and reference wiring. No reprogramming is typically required when the connector and signal type match the original sensor.

• Designed for 12 V vehicle electrical systems and standard MAF signal behavior.
• No module flash expected when replacing like-for-like 3-pin sensors.
• Relearn or idle adaptations may occur automatically as the ECU rebalances fuel trims.
• If a Check Engine light persists, scan codes will indicate whether further diagnosis is needed.

Who is this for: Technicians, DIY mechanics and owners of compatible Chevy, GMC, Cadillac or Pontiac vehicles who need a cost-effective, OE-style replacement MAF sensor. Ideal when the original 3-pin sensor shows intermittent readings, contamination, physical damage, or when an exact-fit part number match is required. If you need broader engine diagnostics beyond the sensor replacement, pair this part with basic intake inspections and a diagnostic trouble-code check to ensure a complete repair.
