<Mode B (measurement of reference pressure for setting the target negative pressure)>
Diagnosis 1
Purpose: Judge the reference pressure stability.
Judge as NG when the following conditions are established.
Diagnosis 2
Purpose: Judge whether the reference pressure is within the normal range, and detect the vacuum pump and orifice malfunctions.
Judge as NG when the following conditions are established.
JUDGMENT VALUE - DIAGNOSIS 1
| Malfunction Criteria | Threshold Value | DTC |
|---|---|---|
| |Pressure sensor maximum output value - Pressure sensor minimum output value| | More than 314Pa (2.355mmHg, 0.1 inHg) | P2404 |
JUDGMENT VALUE - DIAGNOSIS 2
| Malfunction Criteria | Threshold Value | DTC |
|---|---|---|
| Reference pressure for setting the target negative pressure | Less than value of Map2 Or, More than value of Map3 | P2404 |
BAROMETRIC PRESSURE - MAP2
| Barometric pressure (kPa (mmHg, inHg)) | 70 (525, 20.7 inHg) | 80 (600, 23.6 inHg) | 90 (675, 26.6 inHg) | 100 (750, 29.5 inHg) |
|---|---|---|---|---|
| Reference pressure for setting the target negative pressure (kPa (mmHg, inHg)) | -4 (-29.790, -1.2 inHg) | -4.1 (-30.593, -1.2 inHg) | -4.2 (-31.395, -1.2 inHg) | -4.3 (-32.190, -1.3 inHg) |
BAROMETRIC PRESSURE - MAP3
| Barometric pressure (kPa (mmHg, inHg)) | 70 (525, 20.7 inHg) | 80 (600, 23.6 inHg) | 90 (675, 26.6 inHg) | 100 (750, 29.5 inHg) |
|---|---|---|---|---|
| Reference pressure for judgment (kPa (mmHg, inHg)) | -0.9 (-7.065, -0.3 inHg) | -1 (-7.860, -0.3 inHg) | -1.2 (-8.663, -0.3 inHg) | -1.3 (-9.465, -0.4 inHg) |
