Help! Check engine Code

Hi guys. 2006 x45 with 8.1L . Was at idle when the beep alarm came on and the dash read check engine. Throttle was no responsive. could only idle. If i shut off the engine, then restarted, i could drive just fine with no beep. If i sat idle for any amount of time it would happen again. No overheating or low oil pressure. How do i read the code? can i use the same reader i use for my suburban? where would i plug it in? thank you in advance!

I had a similar "Check Engine" code appear on my 2006 MCX 5.7 liter last summer. It happened only when I was manuvering the boat into a gas dock or tight spaces. My initial thought was a bad throttle position sensor (TPS), so I did some internet reading. I came across some threads that this can sometimes be caused by the MC speed control grounds. So I pulled out the switches for the MC speed control and tightenend up all of the electrical connectors. I also added di-electric grease to each terminal. Next, I took off the TPS electrical harness from the throttle mechanism and greased it up too. Finally, I just made sure the throttle lever was properly adjusted and tightened on the shaft. I have had not one problem since. I really think my problem was the ground on the MC speed control. However, I am not sure if you have this setup or perfect pass. If you have the MC speed control, start there and then test. Next grease the TPS harness and test. Finally, make sure your throttle lever is properly positioned / tightened on the shaft.

I hope this brings you the same luck I had.

I dont think you can just use an OBD code reader that the auto industry uses. You need to buy a marine unit. I have never read the codes out of my system, as the only trouble I have ever had was last year. My 3 repairs fixed the problem, so I never got as far as buying a marine reader.

Oh, and be sure to post your findings so others can benefit. I tried 3 fixes at once, so I cannot be sure which did the trick. Like I said, I think my problem was the MC speed control grounds. However I cannot be 100% certain.

Boats do not use ODB2 readers. You'll need to find somebody that has a marine code reader like rinda diacom marine.

Does the paper clip trick work on 2006s? I was able to jump 2 pins on the diagnostic port and then the check engine light would "telegraph" the codes. No code reader needed.
