8.1 fault codes

Mercury2005Mercury2005 ✭✭Bridgeville, DelawarePosts: 130Member ✭✭
Background - left our slip cruising in 6 knot channel for about 10 minutes when the engine faltered, sounded like we hit something.  We anchored for a while and when we left the boat would not accelerate and when into Guardian mode.  We limped back to the slip and shut her down.

Purchased a Rind scanner and got the following faults (with engine running):

 - 191 fuel level 2 circuit high
 - 118 steering position circuit high
 - 75 fuel level circuit high
 - 94 pit.ot presser (boat speed sensor) low

Strange thing is I was able to rev it to the rev limiter and it did not go into Guardian mode.

What do I need to do to correct these faults?

Any help is always appreciated.

    Hmmm, it doesn't seem like any of those codes would be a problem.  Do you have fairly new batteries?  I'm asking because I've seen where low voltage can cause this as well.  Obviously you can clear all codes to get out of guardian, but I recommend finding out what caused the problem.  I know a buddy of mine that used to own the 342 had issues with one of his main electrical connections that went to the ECM as well.  So, maybe check those as well.

    None of those faults will put an engine into gaurdian mode.    Looked into fault history

    Dream, Alswagg, thanks for the input.  I will reconnect the scanner and go through the menu to try to get more info. Will post results after.

    The faults you posted will always appear as your boat does not use these sensors 
  • AlswaggAlswagg ✭✭✭✭✭ Posts: 2,514Member ✭✭✭✭✭
    Did your alarms go off?
  • Mercury2005Mercury2005 ✭✭ Bridgeville, DelawarePosts: 130Member ✭✭
    Alswagg, yest a steady alarm all the way back to the dock. It would not take any throttle at all, had to idle all the way.
  • Dream_InnDream_Inn mod Annapolis, MDPosts: 5,396Member, Moderator mod
    Yes, for a steady alarm, you definitely have something in the fault history.  Could be anything from low oil pressure to high temperature or a faulty sensor.  Please post the history.

    Yes look into fault history and post your readings

    Did you check the reading on the water pressure sensor this will make it go in to limp mode under power but not in  neutral rev

    Can you do real time read with ur scanner 
  • Mercury2005Mercury2005 ✭✭ Bridgeville, DelawarePosts: 130Member ✭✭
    javhav,
    Since I just purchased the scanner, I need to learn how to use all the capability.  All I did so far was plug it in, start the engine and read the faults.  The only faults I got were the ones posted.  There is a 'memory history' or something like that and I will check next time I am at the boat.
    When you say 'real time' do you mean with the scanner plugged in and engine running?  If so I did that and selected 'read faults' which resulted in the faults noted.
    Not sure if I can select certain sensors or just go through the menu, again still learning.
    Any suggestions?
    Thanks,
    Len

    pcm funtions will allow you to go tought each sensor one at a time, this will give reading on each while running. It is a slow process be patient.

    @Mercury2005 @reneechris14 is the correct way to go check all % on the sensor and write them down then it would be alot easier to see what's really going but my scanner screen says pcm parameters so guess each one is different and read while the engine on and up to temp would love to help just need to know the numbers or %

    @alswagg,
    Just reread your post.
    You said - 
    "The faults you posted will always appear as your boat does not use these sensors"
    "Did your alarms go off?"

    If I don't have those sensors, why did the alarm go off and stay steady and then go into guardian mode?
    Thanks

    The faults you posted will not set off alarm
    Fuel  level
    Streering
    Pitot sensor
    There must be a failt in the history that put it in guardian mode.

    Must read fault history 
  • Mercury2005Mercury2005 ✭✭ Bridgeville, DelawarePosts: 130Member ✭✭
    All,

    Just left the boat, here is status:

    Ran the motor for a long time while moving through the scanner menu selections.

    Just after starting one reading said 100% power, moving through the menu while idling I noticed a couple readings that were going up, i.e., 'starboard coolant temp = 141, port coolant temp = 109.

    With the engine running for quite a long time, the alarm horn started and the P&S coolant temps showed:  star over 211 while the port was around 143 and the power was down to 4%.

    I can now assume that the manifolds/risers are where the fault is.

    Should I remove both manifolds and clean them out, replace them or what do you guys suggest?

    Thanks to all for your input, I feel the scanner has paid for itself already.

    forgot to list 'block pressure' = 2.2 psi
  • AlswaggAlswagg ✭✭✭✭✭ Posts: 2,514Member ✭✭✭✭✭
    Your sea water pumps need to be inspected if worn replace as needed.  Too low on block water pressure, too high on engine / manifold temps 
  • Mercury2005Mercury2005 ✭✭ Bridgeville, DelawarePosts: 130Member ✭✭
    Thanks Alswagg, I will remove and inspect and post results.

    Back flush your water intake, could have a clog or pinched hose as well

    I know I am a little late on this one but for others looking in for future support -

    Assume when you say Rinda you mean Rinda Techmate.  I have one and use regularly and yes, you can eval. data real time such as temps, fuel management , etc (albeit one engine at a time).  It also identifies whether you are in Guardian (limp Mode), and of course can reset codes.  I have the 342 Fiesta Fee and as @Alswagg points out, I always see those speed/fuel sensor codes but until pointed out here, didn't realize they are there because they are not connected to anything and as such, will always be there.  Good to know.  Also, I offer this up- There are soft (two alarm beeps) and hard codes (Constant tone).  Again, I learned this on a long trip with a near malfunctioning IAC that soft alarmed for two days until I ran it down with the Rinda.  This is very helpful information below posted by @212Rowboat ;back in 2013: 

    "......Constant tone alarms are for:
    1.) engine coolant temp overheat,
    2.) low engine oil pressure,
    3.) engine over speed,
    4.) exhaust manifold cooling temp overheat
    5.) sea pump PSI low

    Constant beep alarms are for:
    1.) low outdrive lube level.

    Two Alarm beeps every 60 seconds are for:
    1.) Faulty cam,
    2.) IAC,
    3.) MAP,
    4.) MAT,
    5.) knock sensors.
    6.) open/short in the engine cooling temp circuit
    7.) open/short in fuel injector wiring circuit,
    8.) open/short in oil PSI circuit,
    9.) open/short in exhaust manifold cooling temp circuit,
    10.) open/short in sea pump circuit,
    11.) open/short in throttle position circuit - See more at:

    Holy Smokes, don't forget the bilge plug!

    Autodog61,
    Thanks for the message.
    Water temp, oil pressure (I installed a manual OP gauge in the dash) are normal
    So far I have replaced the thermostat, added coolant and connected the Rinda.
    After the engine warmed up the constant alarm came on.
    The ex manifold temp on the star side was 212 degrees when the alarm came on.
    Removed the water hose from that manifold to riser and it seemed to be pumping a lot of water.
    Disconnected the ex man temp sensor and the alarm went away, no surprise there.
    Next removed the water pump (quite a job), disassembled it and noticed wear in both sides of the pump housing, so I ordered a new Hardin SS pump with installed pulley, and a new ex temp sensor.  
    Also ordered direct read temp gauge (automotive style) that I plan to install directly into the exhaust manifolds where the threaded plug is. Can't hurt to know what the temp really is at that location.
    After I install the new pump, I will connect the Rinda and see what happens. I was getting 2.2 PSI at idle for 'block pressure' which I assume is what the pump is putting out.  When I rev the engine the PSI goes up.
    Also I tried to erase the fault codes displayed on the Rinda and they did not go away.
    Any help is always appreciated.
