Subthrottle Sensor Resistance
Connections: BL lead [D] ←→ BR/BK lead [C]
Standard: 4 
6 kΩ
If the reading is out of the standard, replace the throttle body assy.
If the reading is within the standard, but the problem still exists, replace the ECU (see ECU Removal/Installation in the Fuel System (DFI) chapter).

NOTICE
Never drop the ECU especially on a hard surface.
Such a shock to the ECU can damage it.
Lift up the front portion of the fuel tank, and hold it with a
suitable bar or block (see Fuel Tank Removal in the Fuel

Spring Tension Inspection
Since a spring becomes shorter as it weakens, check its
free length [A] to determine its condition.
If the spring of either fork leg is shorter than the service
limit, it must be replaced. If the length of a replacement
spring and that of the remaining spring vary greatly, the
remaining s ...
