OK here is the deal. My car is throwing a dtc 42. I know what that is and what it does. My ? is the trouble tree is telling me "With test light to B+1 probe PCM harness terminal b5." Then it asks "Is test light on?" Where is B+1?
I tested terminal B5 from a ground and I got a light from the second row pins bottom and top but those were the only ones where I got a light. I just put a brand new Accel opti on and it wasn't doing this before but I was having other problems. I know about the dtc 16 and 32 usually being for the opti. Before I go screaming to accel about a new one I need to make sure that it is not a shorted wire or whatever. Can anyone help me with this one please?
