The air mass sensor measures the mass of air inducted by the engine (air flow mass) with great precision. The signal produced by the air mass sensor is used to calculate the amount of fuel injection and in the case of diesel engines also to control the recirculation of exhaust. It is an important component in both the reduction of exhaust and air supply. A defective or dirty air mass sensor can deliver false input signals to the engines central control unit, which in turn sends false information to other components. Defective and dirty air mass sensors deliver faulty signals. This can have the following consequences: >Black Smoke >Power Shortage >Minimal operation Our air flow sensors adopt platinum material as the sensor element and digital circuit which are the latest technology in this trade. The platinum sensor element is exact same to original parts material,it is the key performance of air flow sensor--the response time. Fast response will make the engine more powerful than lower.Its response speed is faster than most competitors. And we also adopt digital circuit where one MCU includes.
