A-Premium Mass Air Flow Sensor 23262343 8‑Pin — Direct-Fit for Chevy/GMC with Humidity & Temp Sensing

The A-Premium Mass Air Flow Sensor 23262343 is a direct-fit replacement MAF with 8 pins and integrated humidity, pressure, and temperature sensing designed for many Chevrolet, GMC, Buick, and Cadillac engines.

This replacement mass air flow (MAF) sensor restores accurate air-measurement data to the engine control module, helping the vehicle manage fuel delivery and ignition timing more reliably. Engineered for bolt-on installation, the unit uses PBT+GF30 and aluminum-alloy components and delivers a measuring range up to 625 kg/h with ±2% accuracy. It fits a long list of GM models and common reference numbers, making it a practical spare for professional shops and DIY mechanics alike.

Will this MAF sensor fit my Chevy or GMC?

If your vehicle is listed among compatible models, the A-Premium 23262343 is intended as a direct match. This unit covers multiple model years and engine sizes across Chevrolet and GMC lineups, as well as many Buick and Cadillac applications. Verify part cross-references and connector pin count before purchase.

• Direct-fit for Silverado 1500, Sierra 1500, Tahoe/Suburban, Colorado, and more
• Covers engines from 1.5L up to 6.6L depending on model/year
• Matches common OE reference numbers such as 23262343 and 22951817
• 8-pin connector and two-bolt mounting for the listed vehicles

How accurate and durable is this replacement airflow meter?

The sensor uses a polymer-glass reinforced housing and aluminum alloy internals to resist heat and vibration. Performance specifications include a measuring range of 0–625 kg/h and measurement accuracy of ±2%, which supports consistent air mass reporting for engine management systems.

• Material: PBT+GF30 with aluminum alloy elements for thermal stability
• Max supply voltage: 17 V — compatible with typical vehicle electrical systems
• Two-bolt, bolt-on mounting with an 8-pin pin-type terminal
• Includes humidity, pressure, and thermal temperature sensors for multi-parameter sensing

What should I check before replacing my vehicle's MAF sensor?

Diagnose the cause of drivability issues before replacement to avoid unnecessary parts swaps. Scanning trouble codes and inspecting intake plumbing, air filter condition, and vacuum lines helps confirm whether the MAF is the source of the fault.

• Scan for engine codes (P0100–P0104 family and related airflow codes)
• Inspect intake tubing and clamps for leaks or cracks
• Replace a dirty air filter before condemning the sensor
• Consult a qualified mechanic if codes persist after swapping the MAF

How does installation and warranty support work?

Installation is straightforward for those comfortable with basic engine-bay work: disconnect the battery, unplug the electrical connector, remove two mounting bolts, and install the new sensor. A-Premium backs this MAF with a one-year unlimited-mileage guarantee and recommends confirming fault codes prior to replacement.

• Bolt-on replacement uses the vehicle’s existing mounting points and connector
• House (cover) not included — uses OE intake interface
• One-year unlimited-mileage guarantee from A-Premium
• Recommended: professional diagnosis or code scan before purchase

Who is this for: This A-Premium MAF sensor is suited to owners and technicians servicing mid‑2010s and newer GM platforms who need an accurate, cost-effective replacement for 8-pin OE-style mass air flow sensors. It is ideal for fleet mechanics, independent repair shops, and experienced DIYers who confirmed fitment and verified airflow-related fault codes. If you need a direct-fit unit that includes humidity, pressure, and temperature sensing and matches common OE reference numbers, this sensor is designed to meet those needs while offering a one-year warranty for added confidence.
