FOllowing manipulations of the wire bundle near plug C111, it appears several DTC codes that would be related to some components (ignition module, O2 sensor) could in fact be caused by wire breakage occuring in the short section of wire bundle near C111. THe wire bundle is tightly held on the engine on one side, and at C111 plug less than 10 inches away. THe engines moves when subjected to torque while the plug is steady on car body. THis causes frequent flexing of wires inside the bundle, and beakeage occurs, intermittend at times since the broken ends are close together.
So, following the actions I have taken, DTC13 and Dtc44 that comes from time to time will be investigated at this location, rather than at the components...as well as the recent loss of cruise control.
I will update this as soon as possible.
