Diagnostic Trouble Code (DTC) Detecting Criteria
GENERAL DESCRIPTION
V: DTC P0101 MASS OR VOLUME AIR FLOW CIRCUIT RANGE/PERFOR-
MANCE
1. OUTLINE OF DIAGNOSIS
Detect for abnormalities in the 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 val-
ue 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.
