That code means a failed temperature sensor on the power bus. It is not user-serviceable.
You can try an SMC reset to see if the error clears:
Reset the System Management Controller (SMC) on your Mac - Apple Support
If that does not work you will need to have Apple evaluate and give you a repair estimate.
