Sharp report fault code throttle air flow correction reached the maximum limit.

The normal range of airflow idle speed is 2.5g/s-4g/s. If it is lower than 2.5, air leakage may occur in the intake system. If it is higher than 4, there may be additional load on the engine.

At present, influenced by the signal parameters of air flow sensor, there are two types: airfoil air flow sensor, hot wire air flow sensor, hot film air flow sensor and vortex air sensor. The first category: wing plate, hot wire and hot film air flow sensor. The unit of the parameter is V, and the range of values is 0-5, with 5V representing the minimum value of intake air and 0V representing the maximum value of intake air. The parameter value is inversely proportional to the air intake, that is, when the air intake decreases, the output voltage increases. Category II: Vortex air sensor. Its parameter unit is HZ or ms, and the range is 0- 1600HZ or 0-625 ms, the value at idle speed is 25-50hz, and the reference value at 2000r/min is 70- 100hz.
