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

A-Premium Mass Air Flow Sensor (3 pins) is a direct-fit replacement sensor for 3.8L OHV V6 GM engines that measures intake airflow to help the engine control module maintain correct fuel-air balance.

This three-pin MAF sensor by A-Premium is built to OEM-equivalent specifications for Buick, Chevrolet, Oldsmobile and Pontiac vehicles that use the 3.8L V6 (OHV) engine. Constructed from PBT+GF30 plastics and aluminum alloy, it bolts into the existing intake assembly using two mounting holes and provides a measuring range up to 480 kg/h with ±2% accuracy. The unit is supplied without O-ring, bolts or housing and is intended for technicians or DIYers replacing a failing or worn sensor.

How does this MAF sensor perform compared to the original part?

The sensor is engineered to match OEM performance in form, fit and function, offering accurate airflow measurement and stable electrical characteristics. Its build materials and ±2% measurement accuracy make it suitable for restoring proper engine management when the original sensor is compromised.

• Terminal count: 3 pins, pin-type terminals for direct connector compatibility.
• Mounting: bolt-on design with two bolt holes; housing not included.
• Electrical limits: maximum supply voltage 17 V; measuring range 0–480 kg/h.
• Materials: PBT+GF30 plastic body and aluminum alloy components for durability.

What do I need to know before installation?

Installation requires basic mechanical skills and confirmation that the vehicle uses the 3-pin 3.8L MAF sensor layout. Because bolts, O-ring and housing are not included, be prepared to reuse original mounting hardware or source replacements if corroded or damaged.

• Inspect connector and wiring for corrosion or damage before installing the new sensor.
• Do not overtighten mounting bolts—tighten to manufacturer torque specs when available.
• Clear any stored engine codes after fitment and verify proper operation with a scan tool or test drive.
• Cross-reference part numbers (e.g., MAS0193, 12568877, 19112543) to confirm match.
