    Engine issues in a 2009 Mitsubishi Triton diesel

    Mitsubishi Mitsubishi Advice Mitsubishi Triton Mitsubishi Triton Advice Mitsubishi Triton 2009

    The check-engine light in my 2009 Mitsubishi Triton diesel comes on and the engine loses power. A diagnostic tool says there’s a massive fuel leak, which is not correct. Filling the tank seems to correct the problem (the engine light goes off and the power returns). The fuel filter and SCV valve have both been replaced.

    This sounds like a case of a split fuel pick-up pipe in the fuel tank. When the tank is full, the split in the pick-up is covered by fuel, so the pump works normally at supplying the injectors with fuel. But when the level in the tank falls, the split is exposed and the fuel pump suddenly finds it’s much easier to suck air rather than fuel. And engines don’t run too well on just air.

    This could be interpreted by a scan-tool as a fuel leak, so a check of the tank’s pick-up tube seems like a good place to start looking. Any actual fuel leak large enough to cause this problem would, presumably, be visible, but it’s worth a check of the fuel rail and return lines as well. Failing that, you could have a dud sensor that is telling the computer there’s a fuel shortage and sending the car into limp-home mode to protect the engine (which would also explain the loss of power). It would also be worth checking to see that the new Suction Control Valve (SCV) is working properly, even though it's brand new.
