Map boost sensor!! I had to replace mine . 

My dynasty had that problem and it was the intellitec board relay in front run box. 

Rev group had my 2006 dynasty emblem but it was 130.00 dollars!!

Check the fuse !! Mine is in clear box mounted over the generator! 

Thanks for the information!! 

Should be a nut under the bottom where it swivels. It has a keeper pin to keep it tight . My pin broke and nut backed off . I would check that nut and see if that is loose. 

I’ve been looking also but haven’t found a good replacement!! 

I had a turbo boost reference sensor go bad and turbo would quit.  Isl 400 Cummins 

My 400 isl had a boost reference sensor go bad and would not make boost! I replaced sensor and all was well.

here is what I can find !

This is oem I replaced on my 2006 dynasty Allison 3000.

Link bad. 

If it has viper security system it is the module for alarm. 

ISL has what they call a wet sleeve around the piston cylinder and the coolant has to be approved for anti cavitation! 

My speedometer randomly stopped and stuck in 1st gear. I replaced speed sensor and that fixed my problem. 

Allison transmission speed sensor!! Tells transmission when to shift and works speedometer! 

Nice job!!!
