Hi
It's the crankshaft position sensor.
The 2 core wire runs from the rightside engine cover to under the tank. It is black plastic coated & is clearly visible.
Check to make sure it hasn't been damaged or unplugged ( highly unlikely). If not you'll need a new one.
Have you worked on it lately.
Edit:
The wires are black & grey & if they are not damaged/disconnected test with an ohmeter across them & the reading should be 336 - 504 ohms.
