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 (0.52 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 is less than 2 liters (0.52 US gal, 0.44 Imp gal) every 60 seconds, extend 60 seconds more 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 2 liters (0.52 US gal, 0.44 Imp gal), the diagnosis counter counts up.
Time Needed for Diagnosis: 60 seconds x more than 16 times
Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
