A-Premium Mass Air Flow Sensor for GM 3.8L V6 OHV - 3‑Pin Sensor Body, ±2% Accuracy

The A-Premium 3-pin Mass Air Flow (MAF) Sensor is a direct-fit airflow sensor engineered for GM 3.8L V6 OHV engines, delivering accurate airflow readings and OEM-level fitment without O-ring or mounting bolts.

Engine air-measurement components like this MAF sensor help the engine control unit calculate correct fuel delivery and ignition timing. This A-Premium unit is built from reinforced PBT with glass fiber and aluminum alloy components to match original equipment form and function. It supports a broad range of late‑1990s to early‑2000s GM cars and trucks that use the 3.8L V6, and it includes the sensor body only (bolts and O-ring not included).

Which vehicles will this MAF sensor replace?

This 3-pin A-Premium sensor is designed for GM models that used the 3.8L V6 OHV engine. It covers many Buick, Chevrolet, Oldsmobile and Pontiac applications from roughly 1999 through 2005. Confirm compatibility by cross-referencing the reference numbers or your vehicle’s existing part.

• Covers Buick LeSabre, Park Avenue, Regal, Riviera (select years listed)
• Fits Chevrolet Camaro, Impala, Lumina, Monte Carlo where the 3.8L V6 is specified
• Includes Oldsmobile 88, Intrigue, LSS and Pontiac Bonneville, Firebird, Grand Prix models
• Reference part numbers: MAS0193, MA180, AHF50M05 and multiple GM indices

How accurate and durable is the sensor for daily driving?

The sensor measures airflow across a range up to 480 kg/h and offers measurement accuracy within about ±2%, providing data precise enough for routine engine control tasks. Its reinforced polymer housing and aluminum alloy parts are chosen for heat and chemical resistance, supporting long-term reliability under normal operating conditions.

• Measuring range: 0–480 kg/h
• Accuracy: approximately ±2%
• Materials: PBT with 30% glass fiber plus aluminum alloy elements
• Maximum supply voltage tolerance up to 17 V

What installation details and connector information should I know?

The unit uses a three‑pin pin-style electrical connector and mounts with two bolts to the intake tract. This listing supplies the sensor only; it does not include the O-ring seal or mounting bolts, so you may need to reuse OEM hardware or purchase replacement fasteners separately.

• Terminal quantity: 3 pins (pin type)
• Mounting: bolt-on with two bolt holes
• Housing: sensor body supplied, no gasket or bolts included
• Designed for V6 3.8L engines only — check your engine code

Why choose this A-Premium replacement over other aftermarket options?

A-Premium builds this sensor to closely match OEM form, fit and function so it installs cleanly and communicates correctly with the engine control system. The sensor’s construction and calibration aim to provide steady readings and minimize false fault codes, helping restore proper engine behavior when the original unit fails.

• Manufactured to meet OEM-style dimensions and electrical characteristics
• Robust materials for thermal and mechanical durability
• Helps clear intermittent airflow-related faults and improve drivability
• Backed by a one-year unlimited-mileage A-Premium guarantee

Who is this for: This A-Premium 3-pin MAF sensor is intended for owners, mechanics and DIY enthusiasts maintaining GM vehicles powered by the 3.8L V6 OHV who need a cost-effective, OEM-compatible replacement sensor body. It’s especially suitable if the original sensor shows airflow-related error codes, intermittent readings, or if you are restoring performance on late‑1990s to early‑2000s Buick, Chevrolet, Oldsmobile or Pontiac models. Always verify fitment against your vehicle’s exact year, engine and part numbers before ordering.
