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.
Judge as NG when the absolute value of the difference between cam signal input position and learning value is out of specification.
- Abnormality Judgment
If the duration of time while the following conditions are met is longer than the time indicated, judge as NG.
JUDGMENT VALUE REFERENCE CHART
| Malfunction Criteria | Threshold Value |
|---|---|
| |Crankshaft position when camshaft position sensor signal is input - Learning value| | >10°CA |
Time Needed for Diagnosis: 5000 ms
Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
NOTE:
Initial standard learning value is the value of crank angle initially input at the production plant. And then it will be updated every time normal judgment has been completed. Learning value will not be updated if NG judgment occurs because timing belt or chain derails suddenly in process or because wrong assembly occurs during servicing.
- Normality Judgment
Judge as OK and clear the NG if the continuous time while the following conditions are established is more than the predetermined time.
JUDGMENT VALUE REFERENCE CHART
| Malfunction Criteria | Threshold Value |
|---|---|
| |Crankshaft position when camshaft position sensor signal is input - Learning value| | <10°CA |
Time Needed for Diagnosis: Less than 1 second
