Description
xOverview
The OYEAUTO Mass Air Flow Sensor MAF Sensor 23256991 is built to read air intake data reliably across a broad range of GM vehicles from 2009 to 2015. Designed to meet OEM-like standards, it aims to deliver a stable signal to the engine control unit, supporting smoother operation under varying driving conditions.
Compatibility and engine coverage
This sensor fits a wide lineup, including Chevrolet Silverado 1500 and 2500 HD/3500 HD, Tahoe, Suburban 1500/2500, Avalanche, and related GMC variants from 2009–2015. Engines commonly covered include 4.3L V6, 5.3L V8, and 6.0L V8, with Cadillac models ranging through 2014. If you’re replacing a worn MAF sensor on a compatible GM vehicle, this unit is designed to align with OEM fitment and electrical interfaces.
Key performance attributes
- Fast, clean signal: the design targets quick response to airflow changes, helping the ECU adjust fuel delivery promptly.
- Stable readings: built to maintain measurement accuracy across a wide RPM range and under engine load.
- Quality construction: durable materials intended to handle heat, vibration, and long-term use.
- Authentic fitment: crafted to align with the vehicle’s electrical connector and mounting points for straightforward installation.
What you may experience on the road
In daily driving, you may notice steadier idle, more consistent acceleration, and a smoother power curve as the sensor provides data to the ECU. These outcomes are influenced by clean intake paths, proper air filtration, and secure electrical connections alongside a correctly matched MAF sensor.
For best results, ensure the air box is clean and the air filter is replaced before installation. A brief battery disconnection can help reset dashboard indicators after the swap.
Warranty and support
OYEAUTO offers a 12-month warranty. If you encounter an issue, contact us for refund or replacement options. Customer support is available to help with installation questions or compatibility concerns.
