It went to Manassas Chrysler this afternoon. Let me know if your sensor fixed the problem.
Here is my reply at the end of the thread that you might find helpful.
Almost always, an acceleration issue with the SRT6 is related to the supercharger coolant pump. The techs almost always replace the temp sensor first because of the air temp codes. But the air temp codes are set, because the coolant pump fails and the air temp goes up. While its under warranty, you might as well have the dealer replace the pump. But here is my little fix to the problem that is cheap and works extremely well. I made my own supercharger radiator spray kit that not only helps the performance of the vehicle, but will lead to longer supercharger and coolant pump life. First add a bottle of redline coolant additive to the coolant reservoir, to make sure the coolant has the best heat dissipation properties (drain some coolant if necessary). I mounted 2 nozzles in front of the supercharger radiator about 5 inches apart, at approximately the center. I used a universal washer fluid pump and some rubber tubing. The pump kicks on, with a boost activated switch, and sprays a water/rubbing alcohol mist on the front surface of the radiator any time it sees boost. I used a 8 inch SPAL electric fan to help pull the mist into the fins at slower speeds. I mounted a manual switch inside to kick on the sprayer, while sitting still, for street and drag runs (you can cool the supercharger coolant/intake temp, for a much better launch) The tank, which is just a washer fluid universal tank, can be mounted anywhere, but I chose behind the passenger seat, on the floor, to keep it cooler and keep the electric pump out of the weather. This sprayer mod, is nothing new, and several companies make them for turbo air to air intercooler, I may just be the first one to try it on a air to water setup. The result, the supercharger coolant temperature, dropped from 220 + degrees, down to 110, which although I haven't measured it yet, I am sure greatly reduces the air intake temps. Since high coolant temps is what is killing the coolant pump, with this mod, my pump will probably last for ever now. The water/alcohol tank has to be filled every 2 - 4 weeks, depending on how heavy your foot is, but is a cheap commodity. For you drag race nuts, I will be doing testing at the strip, with and without the sprayer to see if there are any performance gains.
