Mode table for Evaporative Emission Control System diagnosis
WARNING: This page is about a different variant/trim than selected.
MODE
| Mode | Normal conditions | Diagnostic item | DTC |
|---|---|---|---|
| Mode Z | Nearly same as atmospheric pressure (equivalent pressure of 0 kPa (0 mmHg, 0 inHg)) | CPC is judged to be open. | P0457 |
| Mode A | Pressure is in proportion to amount of evaporative emission. | - | |
| Mode B | Negative pressure is formed due to intake manifold negative pressure | Large leak | P0457 |
| Mode C | Target pressure is reached. | - | - |
| Mode D | Pressure change is small. | EVAP system is judged to have large leak [1.0 mm (0.04 in)]. | P0442 |
