i have a 2004 Dodge Durango Limited 5.7L that has thrown codes:PO442, PO513, B1670, B166F,B1807, B108E, B108F, and U0186. can anyone help me with these?

The po513 is what is causing the "B" codes which are a generic code. By the looks of this, the vehicle should go to the dealer for repair....P0513 DODGE - Incorrect Immobilizer Key...Possible causes; Faulty immobilizer key, Poor electrical connection for immobilizer circuit components, Faulty immobilizer control unit, Faulty immobilizer key antenna...Possible symptoms, Engine Light ON (or Service Engine Soon Warning Light) No or hard engine start situation.

P0442 DODGE - Evaporative Emission Control Small Leak Detected...Possible causes; Missing or loose fuel cap, Incorrect fuel filler cap used, Fuel filler cap remains open or fails to close, Foreign matter caught in fuel filler cap, EVAP canister or fuel tank leaks, EVAP system hose leaking, Fuel tank leaking...The P0442 code means that the control module has detected a small leak in the Evaporative Emission.

U0186 - Lost Communication With Audio Amplifier 'A'
