Judgment Value

MALFUNCTION CRITERIA AND THRESHOLD VALUE REFERENCE

Malfunction Criteria Threshold Value
Integrated times of the condition reaching follows, DELFLMAX ≥ 0.27 - 0.894 V or SUMFL ≥ 25.92 V
At that time, DELFLMAX: Maximum difference of sensor output for 12.2 seconds; SUMFL: Integrated value of the sensor output deviation for 12.2 seconds
≥ 4 times

The diagnosis counter does not count up when the following conditions are completed within 12.2 seconds.

TANK PRESSURE AND VOLTAGE SPECIFICATION

Maximum value - minimum value of change of tank pressure during 12.2 seconds ≥ 0.05 kPa (0.375 mmHg, 0.02 inHg)
Maximum value - minimum value of battery voltage during 12.2 seconds ≥ 0.609 V

Time Needed for Diagnosis:  12.2 seconds x 4 times

Malfunction Indicator Light Illumination:  Illuminates when malfunction occurs in 2 continuous driving cycles.
