Diagnostic Trouble Code (DTC) Detecting Criteria
GENERAL DESCRIPTION
4. DIAGNOSTIC METHOD
Calculate the Max. value (delflmax) and cumulative value (sumfl) of output voltage variation of fuel level sen-
sor during 12.2 seconds. Judge it normal when both max. and cumulative values are not over the threshold
value. Otherwise, when either of them is over the threshold value, the diagnosis counter counts up. Judge as
NG if the counter indicated 4 counts.
Abnormality Judgment
Judge as NG when the malfunction criteria below are met.
Judgment Value
Malfunction Criteria Threshold Value
Integrated times of the condition reaching
follows,
≥ 4 times
DELFLMAX 0.27 ←→ 0.894 V or SUMFL
≥ 25.92 V

At that time, DELFLMAX: Maximum differ-
ence of sensor output for 12.2 seconds;
SUMFL: Integrated value of the sensor
output deviation for 12.2 seconds
