Yezoauto Mass Air Flow Sensor MAF Meter for Chevrolet Malibu & Cadillac ATS 2016-2020 — OE Fit, Fast-Response

Yezoauto Mass Air Flow (MAF) Sensor is a direct-replacement airflow meter that restores accurate air-to-fuel readings for compatible GM vehicles, improving drivability and engine response.

This Yezoauto MAF sensor is engineered as a precision replacement for original equipment numbers such as 23118170, 23366103 and 20787043. Designed and tested to work with a wide range of Buick, Cadillac, Chevrolet and GMC models, it measures incoming air so the engine control module can calculate the correct fuel delivery. The unit is manufactured with calibrated sensing elements, fast-response electronics and a durable housing to match OE fitment and connector layout for an easy swap.

How does this MAF sensor affect everyday driving?

By accurately measuring intake airflow, the sensor enables the powertrain control module to maintain the appropriate air-fuel ratio. That results in more consistent throttle response, smoother idle and predictable acceleration across driving conditions. It won’t alter engine calibration but restores the vehicle’s intended performance when the original sensor has degraded.

• Restores accurate airflow data to the ECU for correct fuel trims
• Improves idle stability and reduces hesitation on acceleration
• Compatible with stock intake plumbing and electrical connectors

Will this Yezoauto unit fit my vehicle and replace OE numbers?

This product is made to match common OE part references used across GM models and fits when those numbers are listed as compatible. Use the vehicle-year/make/model selector to confirm compatibility before ordering. If the OE number on your original part matches one of the references, the Yezoauto MAF is intended as a direct swap.

• Matches OE references: 23118170, 23366103, 20787043 and others
• Fitment covers Buick, Cadillac, Chevrolet and GMC model families listed
• Connector type and mounting points engineered for direct replacement

What are the main features and build-quality assurances?

The sensor uses precision-manufactured sensing elements and an electronic chip calibrated to return accurate airflow signals. Yezoauto subjects each unit to state-of-the-art testing and a strict inspection process to ensure reliable operation. The housing is lightweight yet durable, designed for typical under-bonnet conditions.

• Precision sensing elements for repeatable airflow readings
• Fast electronic response and corrosion-resistant housing
• Quality control testing and one-year after-sales support

How easy is installation and what maintenance is needed?

Installation is straightforward for anyone familiar with basic engine work: unplug the electrical connector, remove the mounting fasteners, swap the sensor and reconnect. Cleaning the intake and replacing air filters helps prolong sensor life, but routine cleaning of the element is typically not required unless contaminated.

• Direct bolt-in replacement — no reprogramming usually required
• Simple electrical connector and factory-style mounting tabs
• Recommended to inspect air filter and intake for contaminants before fitting

Who is this for: drivers and independent mechanics who need a reliable OE-style MAF replacement for Chevrolet, Buick, Cadillac or GMC vehicles listed in the compatibility chart. It suits owners experiencing drivability symptoms tied to airflow measurement—such as rough idle or hesitation—who want an affordable, tested replacement that restores intended engine performance without complicated installation.
