2012 malibu mxz trouble code


Recommended Posts

Yesterday while taking my boat out it began throwing a service engine required light. The boat is a 2012 MXZ with 70 hours. With some further investigation it shows an engine code:

SPN:65591 FMI:7 mechanical system noit responding

Everything with my engine seems to be in range with good oil level, and pressure, as well as engine temp. The engine seems to be running fine as well.

Does anyone have any input on what the problem may be, or some more insight on what this code means?

Have it looked at. Cylinder 1 has misfired at least twice to set that code.


OK thank you. I plan on taking it to the dealer, but I just was curious if I could figure it out.
