I have a 2002 Dodge Caravan with about 80,000 miles on it. The check engine light come on with engine codes P1684, PO442, P0455, and PO456. I cleared the codes one time and drove vehicle for two weeks before the engine light came back on. Engine runs fine and with thecheck engine light on or off. What could be my problem. Thanks Mike
