P2146 and P2149 codes

Me808 - Check your Juice Injector harness plug connectors. Pull them apart and reseat them. Some folks use dielectric grease on the connections.



My Hot Juice would throw the P2146 and P2149 codes sometimes when it was rather cold outside, (below 40), when the truck engine hadn't warmed to 180 degree value. I would only get these occasionally. It's my understanding the Juice fuels about 20% of the available setting at 140 degrees and will give the full amount when the engine temps reach 174 degrees. It may have something to do with this protection feature. I clear them with a code reader but a number of run cycles should clear them if they don't reoccur. It always seemed to occur when I would give it a fair amount of throttle before the full warmup to 180 degrees. Just my 2 cents.
