2020 Subaru Forester P code Page 41

Abnormality Judgment

1. Judge as NG when the judgment value is larger than the threshold value after deceleration fuel cut.

Response time (diagnosis value) greater than Threshold value -> Abnormal

NOTE: Perform NG judgment only during fuel cut, when exhaust gas apparently changes from rich -> lean. Even without deceleration

fuel cut, judge as OK if the value is below the threshold.

2. Judge as NG when the oxygen sensor voltage at a deceleration fuel cut is large. Judge as NG when oxygen sensor voltage is large even

after a long period of deceleration fuel cut has completed.
