Fault code P16C8 is less common than the classic codes but still shows up often enough on Sea-Doo forums that it deserves a clear explanation.
What P16C8 Points To
This code is generally associated with a supercharger or boost related circuit reporting values outside the range the ECU expects during acceleration.
Getting a Clear Answer
Rather than swapping parts on a guess, the M-JET DIAGNOSTIC tool shows the live boost data next to the stored code, making it much easier to see whether the sensor, the wiring or the supercharger itself needs attention.
