Tuning causing P2138 throttle body code? or cooincidence?
a couple weeks ago while tuning, i started hitting full throttle. then received a P2138. basically wires D and E do not match on throttle body. after stabbing the pedal several times, i was able to get it to go full throttle and code never reappeared.truck is never driven at that high of throttle, so i thought maybe a fluke.
Fast forward to now. found the injectors to be leaking at shutoff. swapped in another set(stock) and all was well. except part throttle trims were a hair off now. went and cleaned the maf up and touched up the VE. i was completely done with the ve and truck ran great. turned everything back on as i normally do, flashed it in. fired up and went on drive to check things. made it about 50 ft. and got the P2138 again. except this time ,it comes on within 5 seconds whether i start the truck or not. with zero throttle input. putting prior and original tunes in have made no difference either. havent seen any app1 or app 2 voltages out of whack either ,. did pedal/throttle body take a dump cooincidentally?
