The Chevrolet Explorer air flowmeter has been replaced with a new one, which is not enough.

1. After replacing the sensor, clear the fault code. Make sure there is no fault. There will be no fault indicator. If the fault indicator light is still on, it means that the fault has not been cleared, and it is recommended to check and eliminate it again.

2. After replacing the oxygen sensor, you need to use a special computer to enter the ECU to eliminate the oxygen sensor fault code. If the fault code is not eliminated, even if the oxygen sensor is replaced, the ECU cannot automatically match it.

3. You can check whether the air filter element is blocked. Blocking the air cleaner element will reduce the air intake of the engine. At this time, the oxygen sensor will naturally light the alarm lamp. When we encounter this problem, we only need to replace the new air filter element, and the oxygen sensor fault light will go out after driving for a period of time.
