Well last week I was struck with a 299 code on the interstate going to the Cynthiana, KY truck pull.
I pulled over at a rest stop and cleared the code with the Bully Dog box.
Go the rest of the way, just fine.
Well, on the way back in about the same area of the hills/mountains; the code strikes again
This has me wondering.
Both times the code struck, the truck was running decent rpms down the interstate. Also the engines cruise control was activated and running downhill with little to no fuel but still making boost.
Last time I threw the code, the engine was doing a similar thing.
Using little throttle, if any and making boost with decent rpms (over 2k).
My thoughts, you can all call me an idiot, but this is the data I am seeing when this code hits.
If so, then twinned trucks should be seeing the 299 code.
I never had this condition ever happen with the B1 turbo that the SPS replaced.
Just wondering outloud, what are y'all's thoughts?
BTW. . I previously have cleaned and added dialectric grease the map connections and turbo solenoid connection.
