Yezoauto Mass Air Flow Sensor MAF Meter for Chevrolet Malibu & Cadillac ATS 2016-2020 — Direct OE Replacement, Precision Sensing

Yezoauto's Mass Air Flow (MAF) sensor precisely measures incoming air to help your engine maintain the correct air-to-fuel balance and restore predictable throttle response.

Designed as a direct replacement for several original equipment (OE) units, this Yezoauto MAF meter fits many GM vehicles including Chevrolet, Cadillac, Buick and GMC models. It uses precision sensing elements and electronic circuitry to send accurate airflow data to the engine control module, helping return drivability and fuel metering to factory-like behaviour after installation.

How does this MAF sensor improve engine performance?

By measuring the volume and temperature of air entering the intake, the sensor lets the engine computer calculate appropriate fuel injection. That reduces rough idle, hesitation and uneven acceleration that can occur with a faulty MAF. It won’t increase horsepower by itself, but it restores the correct operating conditions the engine was designed for.

• Direct airflow measurement for accurate fuel trim adjustments
• Fast electronic response reduces lag during throttle changes
• Precision components minimize measurement drift over time

Which vehicles and OE references does this part replace?

This Yezoauto unit is engineered to match the fit and electrical characteristics of multiple GM MAF assemblies. It lists several OE reference numbers so you can confirm compatibility before purchase. Always verify your year, make and model against the product fitment list.

• Common OE references: 23118170, 23366103, 20787043
• Also cross-referenced with AFH70M-78, AFH70M-114 and related numbers
• Fits many Chevrolet, Cadillac, Buick and GMC models from roughly 2012–2022

What are the key features and build quality highlights?

The sensor uses carefully manufactured sensing elements and undergoes testing to ensure consistent electrical output and durability. Quality checks are performed during production to reduce the chance of early failure. The design is compact and intended for direct replacement with no modification required.

• Precision sensing element for dependable airflow readings
• Rigorous testing and inspection during manufacture
• Lightweight, easy to install and serviceable when needed

How do I install and verify the replacement works?

Installation is typically straightforward: disconnect the battery, unplug the factory MAF harness, remove mounting screws, swap the sensor, then reconnect. After installation, check for cleared diagnostic codes and stable idle; a scan tool can confirm proper airflow readings. If issues persist, recheck electrical connectors and intake leaks.

• Replace with engine off and battery disconnected for safety
• Ensure connector and sealing surfaces are clean before fitting
• Clear fault codes and drive to confirm restored drivability

Who is this for: Vehicle owners and independent mechanics who need a cost-effective, OE-referenced mass air flow replacement for select GM models — including Chevrolet Malibu 1.5L (2016–2020), Cadillac ATS (2013–2019), CT6 (2016–2020), and many Buick and GMC vehicles. This part is made for people who want a direct-fit MAF with solid manufacturing controls, clear OE cross-references, and responsive customer support for fitment or warranty questions.
