Detailed Description

Standard Ignition MAS0245 is an emission control sensor used to measure incoming air flow for engine management systems. Accurate airflow input helps the engine control module manage fuel delivery and drivability across a range of Toyota and Lexus platforms. This part cross-references 2-14642 and MA1083 for the same application. It fits 2003-2005 Lexus GX470, 2001-2004 Toyota Sequoia, 1995-2004 Toyota Tacoma, 2000-2004 Toyota Tundra, 1997-2000 Toyota 4Runner, and 1998 Toyota T100. For buyers searching for a Toyota Tacoma mass air flow sensor or a Toyota Tundra MAF sensor, MAS0245 is the direct replacement reference to verify.

Common Issues This Part May Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or stumble during acceleration
• Check engine light related to mass air flow sensor performance
• Poor fuel metering from a failing airflow signal
• Driveability concerns on Toyota Tacoma, Toyota Tundra, or Lexus GX470 applications

Installation Notes and Tips

Confirm connector shape, terminal count, and bolt pattern before installation. Because this is a sensor-only unit, reuse the existing housing where applicable. Inspect the intake tract for dirt, oil contamination, or air leaks before installing the new sensor, and clear diagnostic trouble codes after the repair if required. Verify fitment by year, make, and model for 1995-2004 Toyota Tacoma, 2000-2004 Toyota Tundra, 1997-2000 Toyota 4Runner, 2001-2004 Toyota Sequoia, 1998 Toyota T100, and 2003-2005 Lexus GX470.

Quality Assurance

Standard Ignition supplies replacement electrical and engine management components for service applications. MAS0245 is built with metal and plastic materials and follows the specified OE-style connector and mounting configuration for the listed vehicles.
