Time Needed for Diagnosis:
Low side: Less than 1 second
High side: Less than 1 second
P0101
DTC P0101 MASS OR VOLUME AIR FLOW CIRCUIT RANGE/PERFORMANCE
1. OUTLINE OF DIAGNOSIS
Detect the malfunction of air flow sensor output properties.
Judge as a low side NG when the air flow voltage indicates a small value regardless of running in a state where the air flow voltage increases.
Judge as a high side NG when the air flow voltage indicates a large value regardless of running in a state where the air flow voltage
decreases. Judge air flow sensor property NG when the Low side or High side becomes NG.
2. COMPONENT DESCRIPTION
3. ENABLE CONDITION
4. GENERAL DRIVING CYCLE
Perform the diagnosis continuously after idling.
5. DIAGNOSTIC METHOD
Abnormality Judgment
