When judgment for purge control solenoid valve stuck open NG is made, end the evaporative diagnosis. Cancel the evaporative diagnosis when the OK/NG judgment for purge control solenoid valve stuck open cannot be made in Mode Z.
| Malfunction Criteria | Threshold Value | DTC |
|---|---|---|
| Time to reach target negative pressure | ≥ 35 seconds | P0457 |
| Or mode B time | ≥ 10 seconds | |
| (Min. pressure value in tank when in mode B) - (Tank pressure when mode B started) | < -0.33 kPa (-2.5 mmHg, -0.097 inHg) |
Mode C: (Check pressure rise)
Stop the introduction of negative pressure. (Wait until the tank pressure returns to the start level of P2 calculation.)
Change to Mode D when the tank pressure returns to the start level of P2 calculation.
Judge immediate OK and change to Mode E when it does not return in spite of spending the specified time.
| Tank pressure when starting calculation of P2 | Time for advanced OK judgment |
|---|---|
| -1.3 kPa (-9.75 mmHg, -0.38 inHg) | 18.5 seconds |
Mode D: (Measure amount of negative pressure change)
Monitor the tank pressure change amount when using mode D. In this case, the tank pressure increases, (nears barometric pressure) because evaporation occurs. However, if any leakage exists, the pressure increases additionally in proportion to this leakage. The pressure variation of this tank is P2.
After calculating P2, perform a small leak diagnosis according to the items below.
