[QUOTE="300000 and counting, post: 1492546, member: 10868"] So my truck is at the dealer now, and it has 2 hard codes; the first one is P0102 Mass air flow sensor. The dealership traced the wires and replaced the sensor and the code is still there. The second code is p2291 which is for low injection pressure; once the truck warmed up they checked the actual verse command rail pressure form 5000 to 20000, they said it takes about 20-30 seconds for the actual to reach the commanded. They are thinking the PCM is bad, but wanted me to check with gear head to make sure these codes where not common when using their tunes on a mini maxx. I'm sure they are not common but I'm going to double check with gear head and then have them replace the PCM. The dealership also told me they needed two keys to swap the PCM and I only own one key for my truck, is this true? And will they have any issue reprograming a used PCM to my truck? [/QUOTE]
