Yezoauto Mass Air Flow (MAF) Sensor — Chevy Malibu 1.5L 2016-2020, Cadillac ATS 2013-2019, OE-fit Plug-and-Play

Yezoauto Mass Air Flow (MAF) Sensor is a direct-replacement airflow meter built to restore accurate air-to-fuel measurement and return original drivability for compatible General Motors vehicles.

If your Chevrolet, GMC, Buick or Cadillac shows rough idle, reduced fuel economy, or the check engine light with airflow-related codes, a failing MAF sensor is a common culprit. The Yezoauto MAF Meter is manufactured to match OE fit and function, using precision sensing elements and factory-style connectors so it plugs in where the original part did. It’s intended to deliver stable signals to the vehicle’s powertrain control module (PCM) so fuel delivery and throttle response return to expected levels.

What vehicles and OE references does this Yezoauto MAF sensor fit?

This MAF meter is designed for a wide range of GM engines across Chevrolet, GMC, Buick and Cadillac models spanning roughly 2012–2022. Confirm compatibility by matching the year/make/model or the listed OE reference numbers before ordering.

• Common fit: Chevrolet Malibu 1.5L (2016–2020), Camaro, Blazer, Colorado, Impala and more.
• Cadillac fit: ATS (2013–2019), CT6 (2016–2020), CTS, Escalade families.
• Also fits many Buick and GMC models including Enclave, Envision, Lacrosse, Sierra, Acadia.
• Reference OE numbers included: 23118170, 23366103, 20787043, AFH70M-78, AFH70M-114, 23197633, 23262343.

How does this sensor measure airflow and help engine performance?

The MAF sensor detects the volume of incoming air and sends an electrical signal to the PCM. The PCM combines that signal with data from other sensors to calculate fuel injector pulse width for the correct air-to-fuel ratio, helping the engine run smoothly and efficiently.

• Uses precision sensing elements for accurate airflow measurement.
• Fast electrical response reduces lag in fuel trim adjustments.
• Restores stable signals to the PCM to improve idle and throttle feel.
• Helps recover fuel economy by correcting incorrect air readings.

Is installation difficult and what should I expect during replacement?

Installation is straightforward for anyone comfortable with basic engine-bay work: remove the intake hose and disconnect the electrical connector, swap the old sensor for the Yezoauto unit, then reconnect and reassemble. No special programming is typically required because this is a plug-and-play OE-style replacement.

• Direct-fit connector and mounting points for painless swap-in.
• Lightweight design simplifies handling and positioning under the hood.
• Recommended: inspect intake tubing and air filter while replacing the sensor.
• Clear any stored diagnostic codes after installation to verify operation.

What quality controls and after-sales support come with the Yezoauto MAF?

Yezoauto subjects each sensor to strict assembly checks and testing to ensure reliable operation and long-term durability. The product is backed by a one-year after-sales service promise for customer support and troubleshooting.

• Factory testing and 100% quality inspection before shipment.
• Fast response support: Yezoauto aims to reply within 18 hours for issues.
• Durable construction and materials designed for engine-bay conditions.
• Clear guidance to confirm vehicle compatibility before purchase.

Who is this for? This Yezoauto MAF Meter is ideal for DIY mechanics, independent repair shops and owners of compatible GM cars and trucks who need an affordable, OE-style replacement to restore correct airflow readings and return drivability. If your vehicle exhibits rough idle, stalling, reduced fuel mileage, or diagnostic trouble codes related to the mass air flow sensor—or you simply want a reliable spare part that matches OE references—this unit is a practical choice. Always verify part numbers and vehicle fitment before installation to ensure compatibility.
