• Fits GMC: Envoy, Sierra (1500/2500/3500), Yukon, Yukon XL.
• Check factory part numbers and engine VIN (e.g., VIN G) for 5-pin compatibility.

How does this replacement sensor affect engine performance?

The MAF sensor supplies the ECU with airflow measurements so the engine can calculate fuel delivery and ignition timing. Replacing a faulty sensor helps stabilize idle, reduce hesitation under acceleration, and improve fuel economy when the old sensor was out of spec.

• Improves throttle response by providing accurate airflow data to the ECU.
• Reduces fuel trim errors that cause rough idle and inefficient combustion.
• Helps clear MAF-related trouble codes once the sensor and related faults are resolved.

What does this JTSAUTO unit replace and what makes it reliable?

This MAF sensor is functionally compatible with many OEM part numbers (including 15904068 and 19330121 among others) and is manufactured with OE-grade electronics and a vehicle-specific housing. JTSAUTO backs the product with a one-year warranty and performs component-level engineering to match original fit and function.

• Replaces numerous OEM references (e.g., 2134160, 19330121, 25168491) for broad interchangeability.
• Constructed to match original electrical characteristics and mounting locations.
• One-year warranty for peace of mind after installation.

How do I install and verify this MAF sensor is the right part?

Installation is typically straightforward: disconnect the battery, unplug the old MAF sensor’s electrical connector, remove mounting fasteners, and swap in the JTSAUTO unit. After installation, clear stored engine codes and test-drive to confirm steady idle and proper throttle response.

• Turn off ignition and disconnect battery before replacing the sensor.
• Match the 5-pin connector and housing orientation to ensure correct fitment.
• Clear diagnostic trouble codes and perform a road test to confirm normal operation.
