2012 Engine Code
 

Durmax still calling their 2012's the LML or is it different? Let me know and I can have the GM diesel section updated. :tu:

LMK

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 lb·ft (705 N·m) 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]

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?
