What does the Buick exhaust camshaft position performance fault mean?

[MaryLynn]

Buick exhaust camshaft position system performance fault is reported because the camshaft timing is not set correctly, briefly described as timing too early or system performance. After the vehicle fault is eliminated, the fault code needs to be cleared. When clearing the fault code, it must be strictly carried out according to the fault code clearing method specified for the specific model, and the method of removing the negative terminal of the battery to clear the fault code must not be used arbitrarily.
