It should not. Don't find any record of cross-reaction.

However, just because you may be taking oxycodone and get a false positive for PCP doesn't mean those factors are related. There are a number of substances known to create false positives for PCP.

False positives apply only to initial screening panels. If the test is properly performed, i.e.. confirmed then the error should be detected, PCP ruled out.
