"P" codes?
Hello Dennis and welcome to the forum.
The "P" codes your asking about, appears to be related to your TPS (throttle position sensor). The fault has two categories, the code refers to either your TPS is out of range, or an adaption failure.
While you are capable of using the PWC's onboard diagnostic to see these faults, your not really capable of doing much about it. The "vehicle communication kit", which is used by your local seadoo mechanic, uses this tool to diagnose and reset the parameters that are out of range in your ECM (electronic control module), using the B.U.D.S. (bombardier utility and diagnostic systems software). These two systems more or less replaced the purpose of the MPEM (multipurpose electronic module) programmer in the 4-TEC series.
While there are defined explanations to several of the "P" codes in the manual that the user is capable of understanding and basically working with, several of the "P" codes are only repairable by the mechanic, therefore, aren't even listed in the manual. Your 1202 code was, listed as a problem in your TPS. But the repair seems to be localized to a parameter change that can only be done with the VCK.
