First of all, thank you sir for the pdf. Followed instruction and tested all part in question with multi meter and they all appear in working condition. however, after hooking up everything, CEL and VSC off indicators still on. reseted CEL by disconnecting battery and cleared my OBD2 reading. reconnected battery cable after 15 min then started car, CEL/VSC lights still on, but this time OBD2 scan read P0115 error which I believe is the coolant temp sensor. But the APPS error code disappeared and I am now able to accelerate upon depressing gas pedal. Idle however is very rough and real low, which (correct me if I'm wrong) is related to the defective coolant sensor or bad wiring connection. I'm hoping to find some insights about this matter, thank you!
