RLP Mass Air Flow Sensor (MAF) for GM Trucks & SUVs — Direct-Fit Replace 10393948/23256991, Durable Sensor

RLP Mass Air Flow Sensor (MAF) accurately measures engine intake air for compatible Cadillac, Chevy, and GMC models, replacing OEM part numbers 10393948 and 23256991.

This RLP replacement MAF sensor is a direct-fit aftermarket air flow sensor engineered to restore precise airflow readings to the engine control unit (ECU). It is built with durable sensing elements and tested across temperature ranges to reproduce the original equipment behavior. The unit is compatible with numerous GM trucks and SUVs from model years 2009–2015; check fit by entering your vehicle details before purchase.

How does this MAF sensor restore engine performance?

When a MAF sensor fails or drifts, the ECU receives incorrect air volume data, which can disrupt fuel delivery and ignition mapping. Installing a properly calibrated MLP MAF returns accurate airflow information so the ECU can re-optimize air/fuel ratios and throttle response. This does not promise repairs for unrelated mechanical issues, but it addresses sensors-related drivability symptoms.

• Precision sensing element for consistent airflow readings.
• Tested for wide ambient temperature ranges to mimic OEM behavior.
• Direct-replacement design for easy swap with original mounting and connector.

Which vehicles and part numbers does it fit?

This sensor is manufactured to match fitment for many GM SUVs and trucks produced between 2009 and 2015. It replaces OEM references 10393948 and 23256991 and aftermarket numbers such as AF10060 and MAF300. Always verify fit by using your vehicle make, model, year, and trim in the parts lookup before ordering.

• Compatible models include Cadillac CTS, Escalade; Chevy Avalanche, Silverado, Suburban, Tahoe; GMC Sierra, Yukon (various 1500/2500/3500 trims).
• Replaces listed part numbers: 10393948, 23256991, AF10060, MAF300, and others.
• Locate MAF beside the air intake box inside the engine bay for replacement.

What are the build quality and warranty details?

RLP units use quality components and go through multiple inspections and airflow tests to ensure stable output. The sensor’s construction prioritizes durability under underhood heat and vibration. Each purchase includes a 12-month warranty covering manufacturing defects, with replacement or refund options if the sensor fails under normal use.

• Durable sensing element and robust housing to resist road and engine conditions.
• Multiple quality checks and functional airflow testing before shipping.
• 12-month warranty with customer support for replacement or refund.

How easy is installation and what should I check after replacing it?

Installation is designed to be straightforward: unplug the electrical connector, unfasten the sensor from the intake tube or housing, and install the RLP replacement in the same orientation. Make sure the connector seats fully and any clamps or screws are tightened to the original torque. After installation, clear any check-engine codes and verify idle and throttle response return to normal.

• Direct-fit connector and mounting holes match original locations for a simple swap.
• Inspect the air intake boot and clamps while replacing the sensor to prevent leaks.
• Clear error codes and perform a short test drive to confirm restored operation.

Who is this for: The RLP Mass Air Flow Sensor is aimed at owners and mechanics of late-2000s to mid-2010s GM trucks and SUVs who need an accurate, cost-effective replacement for a failing OEM MAF. It suits DIY installers and professional shops looking to restore proper airflow measurement and help the ECU recalibrate fuel delivery without replacing unrelated engine parts. Confirm fitment with vehicle details before purchase to ensure correct application.
