    Volvo Penta 5.7 no spark

    Not all gauges are accurate, might want to try a different gauge. If you want to test for enough fuel under load, you must test the fuel pressure while you’re under load. When I watch the video you posted it looks like you might be testing without enough load. If you don’t have a helper, I...

    Error code dtc222:tps2 voltage low

    I’m surprised that was your problem, pretty rare for that to fail. I’m glad you got it fixed.

    Warning lights on dash.

    If my memory is correct, the lights get their signal through the black box which watches the gauges. So if the gauges work, replacing the sender won’t help.

    Warning lights on dash.

    That’s not how a VDO dash works.

    Yes, the two TPSs are inside where your finger is. Probably not, only way to know is to troubleshoot it.

    “I ran out of gas. I... I had a flat tire. I didn’t have enough money for cab fare. My tux didn’t come back from the cleaners. An old friend came in from out of town. Someone stole my car. There was an earthquake. A terrible flood. Locusts! IT WASN’T MY FAULT!” J. Belushi January 24, 1949 –...

    What you’re asking me to do might be illegal. While I do agree with civil disobedience in some situations, I’m not sure boat repair is one of them. I do ask that when people are looking at which elected official to give your vote to. Please consider their position on “right to repair” as part...

    Error code dtc222:tps2 voltage low

    Do you have 2 engine lights on your dash, a red and amber? When this happened did they light up or did you get a warning horn or other notification?

    I don’t have a cheat sheet, where I have found the information is in the class study guide, class notes and diagnostic manuals. Unfortunately most of this is copyrighted and I’m afraid to share.

    2010 350 Mag MPI bravo 3 gaurdian mode issue. 5% power

    More than a few times here on iBoats people have posted codes that don’t match anything in the correct diagnostic manual. Usually it seems like they come from SmartCraft/VesselView or Volvo EVC/easy connect. With Volvo I have a conversion sheet. So I was hoping you had some sort of cheat sheet...

    Error code dtc222:tps2 voltage low

    Oops, just reread your post. Says you are at 750 rpm, we call that “forced idle” and a DTC 222 is usually a “derate 2” which holds the engine at about 30% power. You might have more than just this one code. Might need a scan.

    Error code dtc222:tps2 voltage low

    No. This looks to be an electronic throttle body. You won’t believe what this part costs. The good thing is this problem is almost always a wiring issue. You might want to get the service manual and wiring diagram to troubleshoot.

    Warning lights on dash.

    Looks like a “four winns VDO dash” you can google that and look at the CDI website for troubleshooting. And yes they can be trouble. Don’t know if they still do, but 4winns used to sell a new dash that plugged right in. That’s how the dealership I worked for handled this problem.

    Hi @JustJason Where did you find the code 61 definition? My manuals list a different number for an open injector. I would love to know where you found this information.

    2010 350 Mag MPI bravo 3 gaurdian mode issue. 5% power

    Where did you find the code 61 definition? Guardian at 5% is telling you it’s a critical fault. That’s a forced idle situation. My experience has been that it’s common for DTS faults to be the cause of forced idle. Something this critical will set at least one fault, maybe multiple faults...

    Axius repair on used boat Cobalt 303

    If you buy G3, you might still need the dealer numbers. Yes, all of Mercury Marine is down. Nothing online works and as of yesterday, no one seems to know when it will be fixed. I don’t know why it would work on the starboard. The starboard engine is the “master” engine. The port engine is the...
