1. What is the standard value of the data flow of the Buick Excelle XT1.6T air flow meter, and how many grams per second? At a low speed of 2.28 to 2.42 grams, I just replaced a flow meter with a new one today, and it reached 3.89 grams at idle. The fault light is on, and it reports that the fuel correction material is too thick.

2. How to view air flow data flow

To view air flow data flow, first you need to understand the normal data flow range of the air flow voltmeter and pay attention to the type of air flow sensor.

1. Understand the normal data flow range of the air flow meter. In idle state, the air flow rate of a typical vehicle is about 2.5 to 5 grams per second, while that of a small displacement vehicle may be 2 to 4 grams per second, and that of a large displacement vehicle may be slightly higher.

. If it is less than 2 grams per second, it may be due to air leakage in the intake pipe; If it exceeds 4 grams per second, it may be due to air filter blockage or air conditioning on. During rapid acceleration, this value can soar to 2000 to 7500 grams per second, but there are significant differences among different vehicle models. At the same time, some models such as the BMW N52 engine have a higher normal value at idle, reaching 3.55 grams per second. Secondly, pay attention to the types of air flow sensors. There are two common types of air flow sensors. One is a hot wire type, represented by voltage, with a voltage range of 1.2 to 1.6 volts at idle; There are also special types of sensors, such as hot wire or hot film sensors, whose parameter units are volts and the normal range is 0 to 5 volts. If there is no voltage at all or exceeds 5 volts, it indicates that there may be a Yinglang air flow meter data

n abnormality in the state. 3. Based on the actual situation of the missing bird, if abnormal data is found in the airflow data flow, such as below or above the normal range, further inspection of the intake system is needed to determine if there are any problems, such as air leakage or additional loads. At the same time, the evaluation should also be based on the actual working conditions of the vehicle and manufacturer data, and professional equipment should be used for testing if necessary. 4. Observe the performance of the vehicle. If the car experiences unstable idling, weak acceleration, or even black smoke, it may also be due to a malfunction in the air flow meter. At this time, it is also necessary to check the air flow data flow. In summary, viewing the airflow data flow requires a comprehensive judgment based on the specific situation of the vehicle and manufacturer data.

3. What is the normal data flow of an air flow meter? The normal data flow of an air flow meter varies depending on the type: for most air flow meters, the data flow is usually around 2.5g/s. If it is lower than 2.0g/s, it may indicate a leakage in the intake system; If it is higher than 4.0g/s, it indicates that the intake system has a certain additional load of forest potatoes. For hot plate and hot film air flow meters: the parameter unit is V, and the parameter size is inversely proportional to the intake volume. The normal data flow is between 05V. If the air flow meter is damaged, there may be no voltage generated or the voltage may be higher than 5V. The above information is for reference only, and the actual data flow may vary due to factors such as vehicle model, engine type, and specific working environment. When conducting d
