• Helps the engine control unit calculate injection and ignition timing
• Sensor assembly with housing for listed applications
• Global Parts part number 1813377

Detailed Product Information

The mass air flow sensor is a key input device in the intake system. By reporting how much air is entering the engine, it helps the control module adjust fueling and timing for smoother operation and efficient combustion. This Global Parts 1813377 assembly is listed for 2005-2006 Cadillac STS, 2004-2005 Cadillac SRX, 1990-1995 Toyota 4Runner, and 1990-1995 Toyota Pickup, making it a fitment-specific replacement for those vehicles.

This part cross-references Delphi AF10465 for the same application.

Common Issues This Part May Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or poor throttle response during acceleration
• Incorrect air-fuel mixture from a failing intake sensor
• Reduced fuel efficiency related to faulty air measurement
• Check engine light conditions tied to mass air flow sensor faults

Installation Notes and Tips

Verify the vehicle year, make, and model before ordering. For fitment-specific service, compare the existing sensor housing and connector style to the original unit on the vehicle. After installation, clear diagnostic trouble codes and confirm that the engine idles and accelerates normally.

Quality Assurance

Global Parts supplies emission control sensors built for direct replacement use in the listed applications. Part number 1813377 is referenced against OE-style applications for Cadillac and Toyota fitment coverage.
