C-Tzu Mass Air Flow (MAF) Sensor for GM Trucks & SUVs — Direct-Fit Replacement, Fast 30ms Response

The C-Tzu Mass Air Flow (MAF) Sensor is a direct-fit replacement that restores accurate air measurement for compatible Chevy, GMC, Cadillac, Buick and other vehicles, helping clear common MAF-related error codes and improve drivetrain responsiveness.

This replacement MAF sensor (OE cross-references include 25318411, 25168491, AF10043 and many others) is manufactured to meet or exceed original-equipment standards. It’s designed for a fast 30ms response, rugged construction and straightforward installation so you can resolve air-flow faults without sourcing an expensive OEM part. The unit is tested for accuracy, backed by a one-year warranty, and intended for a wide range of GM-platform trucks and SUVs from late 1990s through the 2000s.

Which vehicles and OE numbers does this sensor fit?

This C-Tzu MAF is compatible with a broad list of GM models and several OE part numbers, making it a flexible replacement option for fleet or home repairs. Always verify fitment against your vehicle’s VIN and the OE cross-reference list before ordering.

• Fits: Chevy Silverado, Suburban, Tahoe, Avalanche; GMC Sierra, Yukon, Envoy; Cadillac CTS; Buick, Hummer, Isuzu, Oldsmobile, Pontiac, Saab models — model years vary from late 1990s through mid-2000s.
• Common OE references: 19330121, 25168491, 25318411, AF10043 plus dozens of cross numbers listed.
• Check compatibility by year, engine and connector shape to ensure direct-fit installation.

How does installing this MAF sensor address engine fault codes?

Failing MAF sensors often trigger diagnostic trouble codes related to airflow measurement. Replacing a malfunctioning sensor with a correctly matched unit can resolve codes such as P0100–P0104 when the root cause is the meter itself.

• Designed to clear common airflow-related codes (P0100, P0101, P0102, P0103, P0104) when the sensor is the fault source.
• 30ms response time improves signal accuracy to the ECU for better fuel/air calculations.
• After installation, clear stored codes with a scanner — some vehicles require code reset for the ECU to relearn the new sensor.

What should I know about installation and maintenance?

Installation is typically straightforward for technicians or experienced DIYers, but follow a few precautions to avoid dealing with recurring faults. Ensure the ignition and ECU are powered down prior to swap and clear diagnostic codes if they persist after replacement.

• Turn off ignition (and disconnect battery if preferred) before removing the old sensor to avoid electrical issues.
• Inspect the intake duct and air filter — contamination can damage a new MAF if not addressed.
• After fitting, use an OBD-II scanner to clear codes and confirm the new sensor is reading correctly.

What quality assurances and warranty support are provided?

The C-Tzu MAF is manufactured under controlled standards and subjected to multiple tests to ensure durability and measurement accuracy. The part comes with a one-year warranty and customer support response within 12 hours for warranty or fitment questions.

• Constructed from durable materials and tested to meet or exceed OEM tolerance and performance.
• Multiple inspections for consistent electrical and flow response characteristics.
• One-year worry-free warranty and timely customer service for replacements or guidance.

Who is this for: The C-Tzu Mass Air Flow Sensor is aimed at vehicle owners, independent mechanics and fleet managers who need a cost-effective, reliable replacement for worn or faulty MAF units on GM-platform trucks and SUVs. It’s suited to anyone troubleshooting MAF-related diagnostic codes or restoring engine drivability without buying OEM-priced components, provided they verify fitment with their vehicle’s year and engine configuration.
