Melted 02 Sensor Connector
#11
I'm at a loss. So after everything I have spliced in a new 02 harness all the way back to the ECU. I have tested the plug and have 12v constant to one pin. The heater wire will switch to 12v. One pin is constant 4.5v. The earth/signal wire starts at 0v but I tested it at the ECU and it goes to 4.5v when the engine is running. It still is showing a flat line on the graph and throwing a p0134; Could the wires being melted together cause an ECU problem? Any help would be greatly appreciated.
