Fault code P1505 shows up on Sea-Doo displays often enough that it is worth understanding on its own, rather than just clearing it and hoping it does not return.
What P1505 Points To
This code is generally linked to the idle air control circuit, meaning the ECU is seeing a value from that circuit outside its expected range.
Confirming and Clearing It
Reading the live values around the idle air control system with the M-JET DIAGNOSTIC tool tells you whether the issue is a wiring fault or the component itself, and lets you clear the code once it is resolved.
