CARBBIA Mass Air Flow Sensor MAF for GM Trucks SUVs 2007–2009 — Direct-Fit 2451149 Replacement, Pre-Calibrated

The CARBBIA Mass Air Flow Sensor 2451149 is a direct-fit replacement MAF meter engineered to restore accurate air-flow readings for select 2007–2009 Chevrolet, GMC, Cadillac and Pontiac V8/V6 engines.

When a vehicle’s mass air flow (MAF) sensor fails or drifts, engine performance, fuel metering and drivability can suffer. This CARBBIA unit replaces several OEM numbers — including 281103C100, 19351885 and 245-1149 — and is built to match the electrical and mounting points of the original part for a straightforward swap on many GM trucks and SUVs from 2007–2009.

Will this CARBBIA sensor fit my truck or SUV?

Check the compatibility list carefully: the part is designed for specific Chevrolet, GMC, Cadillac and Pontiac models from the stated years and engine options. Fitment covers multiple engine sizes (4.3L, 4.8L, 5.3L, 6.0L) and includes both gas and flex-fuel variants where noted.

• Compatible makes: Chevrolet, GMC, Cadillac, Pontiac.
• Common models: Silverado, Sierra, Tahoe, Suburban, Yukon, Avalanche, Escalade, G8, Caprice.
• Years covered: primarily 2007–2009 depending on model and engine.
• Engines: 4.3L V6, 4.8L/5.3L/6.0L V8; check exact engine and year before ordering.

How does this replacement match the original equipment?

CARBBIA designed the MAF sensor to align with the OEM electrical connector, mounting holes and airflow housing dimensions so installation is typically plug-and-play. The sensor provides the same signal type and calibration range as the original part numbers it replaces.

• Replaces OEM numbers including 281103C100, 19351885 and 245-1149.
• Factory-style connector and mounting pattern for direct replacement.
• Pre-calibrated to match original signal outputs for engine control units.
• Supplied as a single MAF sensor in the package for one-time replacement.

What are the signs you need a new MAF sensor, and how will this help?

A failing MAF sensor can cause rough idle, hesitation on acceleration, reduced fuel economy or diagnostic trouble codes related to air/fuel metering. Replacing the faulty sensor with a correctly matched unit like this CARBBIA MAF can restore proper air measurement and help the engine control module recalculate fuel delivery and ignition timing.

• Symptoms: check engine light, poor throttle response, stalling or uneven idle.
• Benefit: restores accurate air-flow data to the vehicle’s ECU for better drivability.
• Maintenance tip: inspect air filter and intake for leaks before replacing the sensor.
• Installation: typically a short, bolt-and-plug replacement without modification.

Is installation difficult and what should I expect in the box?

Installation is straightforward for anyone comfortable with basic engine-bay work; the sensor unbolts from the intake housing and the electrical connector unplugs. The package contains one CARBBIA mass air flow sensor — no additional hardware is required for vehicles that match the listed fitment.

• Package contents: Mass Air Flow Sensor x 1.
• Tools: common sockets or screwdrivers typically required for removal/installation.
• Time: average installation time is under an hour for OEM-style replacements.
• Recommendation: clear any stored trouble codes after installation and perform a test drive.

Who is this for: This CARBBIA MAF sensor is intended for owners, mechanics and fleet technicians maintaining 2007–2009 GM trucks and SUVs who need a reliable, direct-fit replacement that matches multiple OEM part numbers. Before purchasing, confirm your vehicle’s year, model and engine match the compatibility list to ensure proper fit and function.
