car recently had intake ported and larger demon performace throttle body installed and keep getting these two codes ? any guesses ? I didn't change anything in the tune since they were installed
Did you do a throttle body relearn? That will cause the P2173 code.
wow I did not , how exactly is it done and also i cleared the code and it seems to come back within a day or so part throttle driving
It's in the vcm scanner.
thanks for help, did a throttle re learn and I also realized under engine diagnosis they have settings for the p2173 and I basically just adjusted the max error values and all been good so far
