I have a 1998 Plymouth Grand Voyaguer V6 3.0 with 140,000 miles and the check engine light keeps coming on. I had a mechanic look at it and said the O2 sensors needed to be replaced. I have done that and the reset the light. The light has now come back on, there are several codes that it displays. They are 12, 43, 72, 55. Can you tell me what those codes mean?
