Mode Table for Evaporative Emission Control System Diagnosis
WARNING: This page is about a different variant/trim than selected.
DTC CHART
| Mode | Behavior of tank internal pressure under normal conditions | Diagnostic item | DTC |
|---|---|---|---|
| Mode Z | Roughly the same as barometric pressure (Same as 0 kPa (0 mmHg, 0 inHg)) | Purge control solenoid valve is judged to be open. | P0457 |
| Mode A | Pressure is in proportion to amount of evaporative emission. | - | None |
| Mode B | Negative pressure is formed due to intake manifold negative pressure | Large leak | P0457 |
| Mode C | Reaches target pressure | - | None |
| Mode D | Pressure change is small. | EVAP system large leak determination. [1.0 mm (0.04 in)] | P0442 |
