Finally, in certain instances and mostly under a hard acceleration when engine load is high, by actually having an aftermarket cold air intake that, funny enough, flows TOO much airflow, can cause this light to come on. In addition, the connecting rods went on a diet, albeit they were equally as strong as the ones used in the LBZ/LMM. Directly supporting the piezoelectric injectors is the Bosch CP4.2 injection pump. Yea. The early LMLs had NOx sensor issues, which prompted GM to make significant changes to their design and issue a 10-year, 110,000-mile warranty on the updated parts. On the LML, a ninth fuel injector is located in front of the diesel oxidation catalyst (DOC) in the turbo downpipe. All the fuses are still good. It is stuck in front of my shop. 2016 Duramax 6.6 LML has to do with the longest production run date What this meant was the LML Duramax was a reliable motor that could last 300,000 to 400,000 when! Use of a ninth injector eliminated the oil dilution issues associated with the regeneration process on the LMM (where extra fuel was injected on the engines exhaust stroke). Any suggestions? Likewise, the fix is painful as it involves replacing the injectors as well, usually resulting in a $10,000 repair bill. However, GM decided to go from better (the LBZ/LMM) to best, the LML.

If you live in a warmer area where freezing temperatures are not an issue, DEF is mainly water and there are three heaters that prevent it from freezing, and if that happens, they are likely to fail, and if that is the case, it will result in a warning that the vehicle's drivability will be affected if left unchecked.

In order to meet ever-increasing emission standards and keep up with the Joneses (at the time, Fords upcoming 6.7L Power Stroke), GM amended the Duramax once more for the 2011 model year. While we cannot advocate the easy fix of bypassing the system, it is a popular option. Your email address will not be published. Other changes came in the form of a higher-pressure Bosch CP4.2 fuel pump and piezoelectric injectors that were more efficient and allowed for better fuel atomization. The increase in overall performance that the 6.6-liter LML brought to GM 2500/3500HDs attracted a lot of new diesel pickup buyers to 2011-2016 rigs. Injection pressure(A) shows 0 kPSI.

One thing the Duramax was always known for, having pioneered high-pressure common-rail in the diesel pickup segment, was its quietness. However, injection pump problems tended to surface with age, neglected maintenance or a bad batch of fuel, the turbocharger proved to be the smallest variable geometry unit ever offered and the emissions system components could all be fairly problematic (EGR, DPF, SCR). It looks like nothing was found at this location. Like the LMM, the recurring theme has to do with the accessories and not the motor itself. The truck just died while driving.

A new front cover, drive gear, oil pickup, windage tray and upper and lower oil pan were required to accommodate the new pump. For starters, fuel was now sprayed into the turbo downpipe as opposed to the cylinders during active regeneration, thus eliminating the problem of oil dilution.
