My 89 Shadow 2.5l TI died out on me the other day and it popped a code 54. I checked the HEP wires and connectors and they look good, so I did some research and found that a shorted out oxygen sensor signal wire will also cause a code 54. When I checked the connector I found that it's all melted like it was sitting on the exhaust manifold. I can't find the harness side of the connector, are there any other options other than trying to find one in a junkyard?
Thanks for looking.
