Wondering if anyone has tried / had success disabling any of the P154A/B/C/D codes for their Duramax? Truck is a 2016 with a perfectly functioning IAH and an intermittent ghost code P154B. Thanks!

This has been resolved, removing the code would not have changed anything. The actual reason the code was setting was G122 was corroded on the engine block which caused high resistance on pins 8 and 10 for the GPCM connector. Didn't occur all the time, but when it did the code set. Cleaned the ground and the main ground cable below it and all is well.
