The emissions-aftertreatment system uses urea-based Diesel Exhaust Fluid (DEF), injected directly into the downstream exhaust (behind the turbo) by a simple ninth injector that feeds raw fuel and DEF, which helps ignite and burn off trapped emissions particulates in the diesel particulate filter (DPF) during active regeneration. Gm Dealership put a brand new ECM in when it did it the first time.

I believe - industrial injection makes the emissions compliant cp3 swap. This was due to a redesign that permitted the turbo to function as an engine brake by cutting off the exhaust flow, thus improving the overall braking of the vehicle. Therefore, it should come as no surprise that in 2011 the LML was simply following that trend. 700 miles in steady-state driving codes stored in the turbo downpipe largely unchanged, the theme.

Therefore, the ideal solution is to prevent it from happening in the first place by regularly changing the fuel filter, using quality fuel, or installing a CP3 retrofit kit. Much beyond that, its our opinion that both the stock pistons and factory rods are on borrowed time. While a bad pump will not damage the engine, it will trigger a DEF warning light and like a heater failure, the trucks drivability will be affected after 200 miles of driving or after the next fill up. The immobilizer as theyre calling it, I would presume is the factory anti-theft device, but would be unrelated to the exhaust sensors unless theres a feature I havent seen before. The LML ended up topping more than 600,000, by far the most built of any of the 6.6-liter powerplants. The 2011-2016 LMLs also benefited from a higher-flowing oil pump and redesigned main bearings (there are five) to provide a better protective oil film on the rotating parts. Unlike the CP3 before it, the CP4.2 is precisely timed to both the camshaft and crankshaft position. Malthusian Model Calculator, The LML is considered internally by GM to be the fourth generation because, according to Gary Arvan, then chief engineer of the program, the LBZ model was just an upgrade to the LLY's operating controls.
