Thanks for the link, I already read it completely and tested a few things.
The voltage to the sensor is OK, but I have no way of reading the output voltage.
However when the sensor is plugged in, my fuel pump cycles 1 second and then stops when I turn my ignition on. The bike won't start with the sensor connected.
With the sensor disconnected, the fuel pump cycles 3 seconds and then the bike starts for 5 seconds and cuts out.
So should I just get a new sensor?
There is no out of circuit test, however I have drawn out what I think the internal connection looks like. Since you have followed 3-59 to 3-60 of the service manual, the BL ( blue) positive
and BR/BK ( brown with black tracer ) negative
are the input terminals and the center Y/G ( yellow with green tracer) is the output to the ECU.
Take the sensor out of the bike, it mentions not to drop it. Measure the input terminals ( outside terminals ) using a ohm meter, this measurement should be stable irregardless of what position you are holding the sensor.
Next measure from what would be the BL terminal with the sensor vertical to the center what would be the Y/G, note that reading, repeat for the BR/BK to center terminal , record your readings and post.
Since the ECU is looking for a positive 3.55 to 4.45 VDC input, you could try using a 100,000 ohm resistor between the BL and Y/G , try starting the bike and see if it runs for more than 5 seconds ( FYI you do this at your own risk and if it works you need to replace the sensor).
