This engine is not yet commercially launched although it was touted in the automobile press as one of the most important new engine concepts for small trucks and SUVs by finally delivering a capable diesel engine in a compact enough package. The engine project is current on indefinite hold by GM. General Motors planned a 4.5-litre 72-degree[9] V8 for light-duty applications which would be built at GM's powertrain facility in Tonawanda, New York after 2009. Designed to fit in the same space as a Chevrolet Small-Block engine, it is expected to produce over 310 bhp (230 kW) and 520 lbft (705 Nm) of torque. It added urea injection, 29,000-psi (2,000 bar) piezo-electric common-rail fuel system over previous Duramax architecture.[10]

It was initially targeted for the Chevy Silverado/GMC Sierra and Hummer H2.[11] Unlike previous Duramax engines, the 4.5-liter is planned to be designed and built entirely by GM, without assistance from Isuzu.[12]

Default 2012 Duramax p2263 code

My 2012 Duramax keeps throwing the p2263 code at me. I have tried several things to fix it including taking it to the dealership and letting them deal with the pigtails and taking it to experts to have them delete the codes. at this point, I cannot travel more than 50 mph. and have to constantly delete the codes. when I have taken it in, the codes only disappear for about a week. Has anyone else had this problem?
