( Part Type: Intake Flow Sensor Meter ), ( Manufacturer Part Number: 22250-45030 )
The Toyota 22250-45030 Air Flow Sensor Meter (AFSM or MAF) is an essential component of the air intake system in certain 79 Celica Supra models equipped with the 4ME-2.8 engine. This sensor plays a crucial role in ensuring optimal engine performance by accurately measuring the volume and the mass flow rate of the air entering the engine.
This specific air flow sensor meter from Toyota is meticulously designed to meet OEM (Original Equipment Manufacturer) standards. It features a compact, yet sophisticated design, with a rectangular shape and dimensions of approximately 6.1 inches in length, 2.6 inches in width, and 1.1 inches in height. The sensor housing is made of high-quality, engineered plastic material that is resilient to temperature fluctuations and other harsh environmental conditions.
The heart of this air flow sensor is its heating element, which is responsible for maintaining the sensor at a consistent operating temperature. This is crucial for accurate air flow measurement, as the sensor's electrical resistance changes with temperature, affecting its ability to measure air flow accurately.
The sensor's electrical connector is designed to be easily accessible, making installation straightforward. It features a total of six wiring pins: power, ground, heater, signal, ground for heater, and temperature sensor. The wiring harness is shielded to protect against electromagnetic interference.
The air flow sensor meter is calibrated to work seamlessly with the engine control module (ECM) in your Celica Supra. It sends real-time data on the air flow rate, which the ECM uses to calculate fuel injection and ignition timing for optimal engine performance.
This Toyota genuine OEM part is built to last, with high-quality materials and precise manufacturing processes. It is designed to provide reliable, accurate performance over the long term, ensuring that your 79 Celica Supra continues to run smoothly and efficiently.
In summary, the Toyota 22250-45030 Air Flow Sensor Meter is a vital component of the air intake system in your Celica Supra, ensuring optimal engine performance and fuel efficiency. Its compact, durable design, and precise calibration make it an essential upgrade for any Celica Supra enthusiast seeking the best possible driving experience.
