Please clean up the mass air flow sensor, or check if the sensor is good. You can buy a cheap one from Amazon. I'm a specialist to fix Check Engine Light.
Good Luck.

我檢查過Sensor,應該是正常的。兩條黑線(加熱器)之間電阻2.5歐姆,藍線和白線之間,熱車時是 0.75V 。

那壞的那支呢? 量的數據確定是壞的? 例如兩黑綫間是open的

2019-09-21 17:19:32 我用另外一個Sensor(好的那個)來對照,發現測量結果非常接近

根據測量,新買那個Sensor應該是好的。接口看來也很幹淨沒鏽。接線還很好。隻好消了碼後再繼續觀察。

O2 voltage must varies with time, cannot stuck at 0.75v

明白。萬用表的讀數其實一直在變,不過普通萬用表反應慢,一開始讀數低,過幾分鍾就會停在比較高的讀數。

可以用示波器來看,不過嫌麻煩,不過有空可能會試試。
