Judgment Value: Overview
JUDGMENT VALUE
| Malfunction Criteria | Threshold Value | DTC |
|---|---|---|
| (Tank pressure when Mode Z started) - (Tank pressure when Mode Z finished) | </= 0.4 kPa (3 mmHg, 0.12 inHg) | P0457 |
JUDGMENT VALUE
| Malfunction Criteria | Threshold Value | DTC |
|---|---|---|
| (Tank pressure when Mode Z started) - (Tank pressure when Mode 2 finished) | > 0.6 kPa (4.5 mmHg, 0.18 inHg) | P0457 |
| Tank pressure when Mode Z started | >/= 1.43 kPa (10.7 mmHg, 0.42 inHg) | |
| Time for no fuel rolling of 2 lambda or more | >/= 40 seconds |
Time Needed for Diagnosis: 16 seconds
Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
Finish the EVAP. diagnosis when making NG judgment for purge control solenoid valve open fixation.
Cancel the EVAP. diagnosis when the OK/NG judgment for drain valve close fixation and purge control solenoid valve open fixation cannot be made in Mode Z.
- evptezini, evptez </= 1.43 kPa (10.7 mmHg, 0.42 inHg)
- evptez - evptezha </= 0.87 kPa (6.5 mmHg, 0.26 inHg)
- evptezini - evptezha </= 0.87 kPa (6.5 mmHg, 0.26 inHg)
- No fuel rolling of above 2 lambda (0.79 US gal, 0.67 Imp gal) for more than 40 seconds.
Judge normal when all calculations are completed.
