So i have 2003 nissan maxima gle 3.5 and it had a bank 2 cam position sensor code. Replaced it.. still no start. Messing and messing with it.. found a thread on security system. Went out and went through on/off procedures and it started. Got excited.. but it still seems to be a irritating situation everytime we start it.. blower motor for hvac wont shut off when key is turn to acc. Or running... all happened at same time. But with it running the bank 2 code still exist.. with my entry level code reader.. i erase that code.. car dies.. please help my kid is frustrated and so am i thx
