Diagnostic Method
WARNING: This page is about a different car, the 2012 Subaru Forester. However, it is still accessible from the selected car via links, so may be relevant.
Measure the pressure values when the enable conditions are established, and perform diagnosis by calculating those results.
- Label the intake manifold pressure value as PMOF1, which is observed when enable conditions are established, and set the EGR target step to 50 steps (nearly full open).
- Label the intake manifold pressure value as PMON, which is observed after one second has passed since EGR target step was set to 50 steps (when the enable conditions were established), and set the EGR target step to 0.
- Label the intake manifold pressure as PMOF2, which is observed after one second has passed since EGR target step was set to 0 (after two seconds have passed since the enable conditions were established).
- Abnormality Judgment
Judge as NG when the following conditions are established.
- Abnormality Judgment
JUDGMENT VALUE REFERENCE CHART
| Malfunction Criteria | Threshold Value |
|---|---|
| PMON - (PMOF1 + PMOF2)/2 | < 2.5 kPa (18.63 mmHg, 0.7 inHg) |
Time Needed for Diagnosis: 1 time
Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
- Normality Judgment
Judge as OK and clear the NG if the following conditions are established.
JUDGMENT VALUE REFERENCE CHART
| Malfunction Criteria | Threshold Value |
|---|---|
| PMON - (PMOF1 + PMOF2)/2 | ≥ 2.5 kPa (18.63 mmHg, 0.7 inHg) |
Time Needed for Diagnosis: 1 time
