dealer informed that evap sensor and tcc trans are on 1640 code solution was eliminate evap by key on, wires to sensor measure 12v and solenoid when connected allow air to pass. tcc on wiring diagram colors found and had power sooo the round connector had a pin bent and therefore not connected, straighten pin ALL GOOD
