3-46 FUEL SYSTEM (DFI)
Throttle Sensor (Service Code 11)
Remove the ECU (see this chapter). Do not disconnect
the ECU connectors.
Connect a digital meter [A] to the connector [B], using the
needle adapters [C].
Special Tool - Needle Adapter Set: 57001–1457
Insert the needle adapter straight along the lead in
the connector to prevent short circuit between ter-
Measure the output voltage of the sensor with the engine
stopped, and with the connector joined.
Turn the ignition SW ON.
Throttle Sensor Output Voltage
Connections to Sensor
Meter (+) → Y/W lead (terminal 26)
Meter (–) → BR/BK lead (terminal 11)
0.584 ~ 0.604 V DC
(at idle throttle opening)
4.29 ~ 4.59 V DC
(at full throttle opening)
If the output voltage is normal, replace the ECU.
If the reading is out of the standard range, inspect the
throttle sensor resistance.
After throttle sensor inspection, remove the needle
adapters, and apply silicone sealant to the seals [A] of
the connector [B] for waterproofing.
Silicone Sealant (Kawasaki Bond: 56019-120)
- Seals of Connectors
Turn the ignition switch OFF.
Disconnect the throttle sensor connector.
Connect a digital meter [A] to the throttle sensor connector
Measure the throttle sensor resistance.
Throttle Sensor Resistance
Connections: BL/W lead [C] ←→ BR/BK lead [D]
4 ~ 6 kΩ
If the reading is out of the range, replace the throttle sen-
sor along with the throttle body.
If the reading is within the range, but the problem still
exists, the ECU is suspect. Replace the ECU.
