actually no.
PCM and chip tested Good.
I spent yesterday tracing wires, found the problem was on the engine side of the 42 pin harness a section was rubbing on the HPOP hose.
I had already disconnected all the 5v ref sensors and the WTS light was not present so I disconnected the connector to isolate the wing from the PCM and the WTS light came back.
