Diagnostic Method
- Abnormality Judgment
Judge as NG when the malfunction criteria below are met.
Judgment Value
| Malfunction Criteria | Threshold Value |
|---|---|
| Number of times the difference between the Max. fuel level and the Min. fuel level every 60 seconds is 2 l (0.53 US gal, 0.44 Imp gal) or more (with enable condition completed) | ≥ 16 times |
| Maximum - Minimum Tank Pressure (with enable condition completed) | < 0.05 kPa (0.375 mmHg, 0.02 inHg) |
| Maximum - Minimum Fuel Temperature (with enable condition completed) | ≥ 7°C (12.6°F) |
If the maximum value - minimum value for the fuel level every seconds is less than 5 liters, extend 60 seconds and make judgment with the maximum and minimum values for the fuel level in 120 seconds. If a difference does not appear though the time was extended 60 seconds, extend the time (180,240,300 seconds) and continue the judgment. If the maximum value - minimum value for the fuel level is more than 5 l , the diagnosis counter counts up.
Time Needed for Diagnosis: 1 minute x 16 times or more
Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
