p1188 faults the throttle inlet pressure sensor. WHen im boosting at 15psi sometiems i get that code. RIght now i have my EBC set at 12psi. I want to see if it triggers or not. If it does not, then I will raise it till it finaly gives me the fault. I will then come up with a solution on preventing this from happening.
Anyways, you can clear it buy disconnecting the battery for a few seconds.
