24 vehicle speed sensor, does speedometer work? 55 prom error, prom / chip missing or damaged or ecm.67 not sure I think it is a switch code. 55 is the one to be concerned about. Check grounds first , they are on intake and passenger side head.Hope it helps

Hey there Smoney: On the CCC system the 55 code a number of things but slowroll is right that's the one to be concerned about. It can be faulty oxygen sensor circuit , faulty ECM, grounded supply terminal 19 0n ECM, grounded reference terminal 21 on ECM. I think the 67 is the cruise control circuit.
