2012 22 MXZ with Indmar 6.0L has low MAP sensor reading
WY22MXZ posted a topic in Maintenance, Tech Info & Troubleshooting
I was out on the lake and noticed I couldn't achieve full power. When skiing I couldn't reach 30MPH and while surfing I couldn't get over about 9 MPH. The same problem happened last year but then went away. The boat ran good for most of this year and then this last trip out it did it again. I was having problems with the O2 sensors but sense replaced them and no current error codes. The boat does nto show any codes at this time. I have a 2012 22MXZ and the MAP sensor is reading low. Around 9 inHG. I checked the manifold pressure with a gauge and it is right where it should be at 15 inHg. I replaced the MAP sensor and had the same reading so I put the original back in. The Pedal position sensor 1 voltage and Pedal position 2 voltage read the same at idle. Around 0.80 VDC. I'm told these should ad up to 5 volts like the throttle sensor does. I disconnected the transmission temp sensor and jumpered the contacts and no change. I disconnected the depth gauge and the paddle wheel and no change. I disconnected the throttle and did get an error code but no change on the MAP sensor reading. Any thoughts?
