OTO-KAUTOPARTS OTO-K Mass Air Flow (MAF) sensor is a direct-fit replacement that measures engine intake air and delivers accurate signals to the ECU for proper fuel and ignition control.

This MAF sensor is designed to fit specific GM 1.5L turbocharged engines: Chevy Equinox (2018–2022), Chevy Malibu (2016–2022) and GMC Terrain (2018–2022). Built as a plug-and-play replacement, it uses the same mounting points and electrical connector as the original equipment to simplify installation.

How does this MAF sensor work within the engine system?

The sensor measures the volume of air entering the engine and converts that measurement into an electrical signal the engine control unit (ECU) uses to adjust fuel injection and ignition timing. Accurate airflow readings help the ECU maintain the intended air/fuel ratio and engine responsiveness. This is a monitoring device, not a performance enhancer.

• Measures intake air volume and converts to ECU-ready electrical signals.
• Helps the ECU set fuel injection quantity and ignition timing parameters.
• Replaces OE-style MAF with matching connector and mounting points.
