Mass Air Flow Meter (MAF Sensor) — part number 22680AA280 Why you need this MAF sensor Restores accurate airmass measurement to the engine control system so fuel delivery and ignition timing are correct. Solves drivability problems caused by a faulty MAF: rough idle, hesitation, poor acceleration, and reduced fuel economy. Acts as a directfunction replacement for the worn or damaged MAF assembly that triggers diagnostic trouble codes (DTCs) and Check Engine light. Key benefits Reliable airflow measurement that helps the engine ECU maintain proper fuel trim and combustion. Quick to normal performance and drivability after replacement. Helps prevent longterm engine and emissions issues caused by running with incorrect air/fuel ratios. Product attributes Part number: 22680AA280 — matches vehicles and procedures that specify this MAF part. Functionality: senses the volume/mass of intake air and sends a voltage or frequency signal to the engine control module. Construction: integrated sensing element and sealed housing with an electrical connector for a single harness connection. Performance: provides the precise airflow data required for stable idle, smooth throttle response, and optimized fuel economy when installed and functioning correctly. Fit and installation: designed to the original MAF assembly identified by part number 22680AA280 and to mate with the vehicle's existing intake plumbing and electrical connector (plugandplay on compatible vehicles). Common applications / use cases Replacement for a failed MAF after a diagnostic confirms the sensor is out of specification or causing fault codes related to airflow. Preventive maintenance when restoring engine performance during a tuneup or after intake repairs to ensure the ECU receives correct airflow input. Diagnostic and troubleshooting use: swap in a knowngood MAF (part 22680AA280) to isolate drivability issues such as stalling, hesitation, or inconsistent idle. What to expect after installation Faster throttle response and smoother acceleration if the previous sensor was degraded. Improved idle stability and a reduction or elimination of airflow related trouble codes. Better fuel economy and lower emissions when the ECU can accurately compensate for incoming air. Installation notes Confirm vehicle requires part number 22680AA280 before . Handle the MAF sensor carefully; avoid contaminating the sensing element with oils, solvents, or debris. Reuse the factory intake clamps and mounting hardware unless damaged; follow vehiclespecific torque and installation procedures. After installation, clear any stored codes and allow the engine to relearn idle/fuel trims as recommended by the vehicle manufacturer. Important reminder and install this MAF sensor only if the vehicle's parts manual or diagnostics identify part number 22680AA280 as the correct replacement. Compatibility is determined by the vehicle's specified part number.
