Hi. We recently purchased a 2008 L200 Diamond. After picking the truck up, we drove 150 miles home without an issue, the truck drove faultlessly. A couple of days later, on a short journey, the L200 went into limp mode showing the EML and TC lights, we lost power and was down to 10 mph with no or very little throttle response. After switching the engine off and on 4 times the lights extinguished and power was restored. A scan showed only one DTC, P0093 (large fuel leak). This has happened several times since at varying distances from startup, every time the fault clears by cycling the ignition. I have inspected for leaks (none found), I have checked the engine oil level (no increase in level, so no leaks under the rocker cover), I have monitored the fuel pressure and all appear to be within tolerance although the fault has not returned while recording fuel rail pressure. The owner did state that the injectors were refurbished last year and recoded to the ECM by Mitsubishi. Any advice would be greatly received.

I was thinking about that, or the fuel rail pressure sensor. I doubt itís anything mechanical as the fault clears immediately, deffinatly an intermittent fault.. Am I right in understanding the suction control valve needs adapting to the ECU? What would happen if I swap the part with our other L200 to prove the issue? Will it start and run?

There not silly money so will change it. Did you have yours adapted / learned to the engine ECU.

Yeah . I not sure whats involved . But there was a bit of magic done .
I think will run on a straight swap but not as smooth as it should . Maybe someone knows how to program a new one to ecu . If its something like hold a button while turning ignition on then it would be something you can do but i have no idea on thatvas i left mine to the garage.
