C0073 and C2161 often appear together on Sea-Doo diagnostic reports, which is why owners searching for one usually end up asking about the other too.
What These Codes Mean
Both are chassis-side codes typically linked to wheel speed or stability related sensors feeding inconsistent data to the control module, rather than an engine problem.
Reading Them Correctly
The M-JET DIAGNOSTIC tool lets you view both codes together with their freeze frame data, which makes it much easier to tell if they share a single root cause.
