Hi all I've got a 2003 seadoo 4 tec, and having problems with it idleing, I've took the idle control valve out and cleaned it but no joy
I was wondering what voltage should I be seeing at the wires going to it, the valve doesn't seem to be doing a lot and have the code p0505
Hope someone can help
cheers
 
Potential causes are:
IAC motor connector is damaged (check connector and pins for damage, and moisture) One or more IAC circuits open or shorted to ground One or more IAC circuits are shorted to voltage IAC has failed PCM has failed

Start by clearing the fault codes. Then unplug the IAC and start the engine (This may cause other IAC codes to set. Just ignore them for now). If the P0505 code doesn't reset, replace the IAC. It is internally shorting one of the IAC circuits. If the code DOES return after unplugging the IAC and starting the engine, then you know it isn't the IAC motor. Visually check the wiring harness all the way back to the PCM. You may need to visually inspect the harness by removing all the insulation off the wires. It is possible that the wires could be shorting to eachother or to other wires in the harness. If there are no wiring problems, and the code keeps returning with the IAC unplugged, you can check the PCM by removing the IAC wires from the PCM connector (or clipping the wires in a location where they can be repaired easily) and then start the engine (If you're not sure, don't do it. Take it to a qualified professional). Now if the code doesn't reset there is a problem with the wiring. Check for continuity on all the IAC wires. Any resistance points to a problem. Check for voltage on any(At this point there shouldn't be any voltages on the wires because they're clipped at one end and unplugged at the IAC). Repair as necessary. But if the P0505 code DOES reset after removing the IAC wires from the PCM connector (or clipping them), replace the PCM, there's a problem internally on the IAC control circuit.
