Technical Details and Compatibility

The MAS0245 mass air flow sensor from Standard Ignition is engineered to meet OEM specifications for Toyota and Lexus models including the 4Runner, GX470, Sequoia, T100, Tacoma, and Tundra. Featuring a bolt-on design, this sensor uses a female rectangular connector with a single connection point, ensuring a straightforward replacement process. The sensor incorporates five male blade terminals housed in a metal and plastic body, providing durability and consistent performance. Note that this part includes the sensor only and does not come with a housing.

Common Applications and Problem Resolution

This mass air flow sensor is used to measure the volume and density of air entering the engine, which is critical for fuel injection and emission control systems. Replacing the MAS0245 sensor can address issues such as:

  • Engine hesitation or stalling during acceleration
  • Check engine light triggered by airflow sensor faults
  • Poor fuel economy due to incorrect air-fuel mixture
  • Rough idling or inconsistent engine performance
  • Failed emissions tests related to air intake measurement

Installation Notes and Tips

Installation of the Standard Ignition MAS0245 sensor requires unbolting the old sensor and securing the new one using the two bolt holes provided. Ensure the female rectangular connector aligns properly with the vehicle’s wiring harness. Handle the sensor carefully to avoid damage to the blade terminals. Since the housing is not included, reuse the existing housing from the original sensor. It is recommended to disconnect the battery before installation to prevent electrical shorts.

Quality Assurance and Warranty

Standard Ignition parts are manufactured to meet or exceed OEM standards, ensuring reliable performance and durability. The MAS0245 mass air flow sensor undergoes rigorous quality control testing.
