Kawasaki Ninja Service Manual: Subthrottle Sensor Output Voltage Inspection

Kawasaki Ninja Service Manual / Self-Diagnosis System / Subthrottle Sensor (Service Code 32) / Subthrottle Sensor Output Voltage Inspection

Disconnect the subthrottle sensor connector and connect the setting adapter [A] between these connectors.

Subthrottle Sensor Output Voltage Inspection


Special Tool - Throttle Sensor Setting Adapter: 57001 -1538

Subthrottle Sensor Output Voltage Connections to Adapter: Digital Meter (+) → R (sensor BL/W) lead Digital Meter (–) → BK (sensor BR/BK) lead

Subthrottle Sensor Output Voltage Inspection


Output Voltage Standard: DC 0.8 1.0 V at
subthrottle valve full close position (for reference) DC 4.28 4.32 V at subthrottle valve
full open position

NOTE

If the reading is out of the standard, check the subthrottle sensor resistance (see Subthrottle Sensor Resistance Inspection).

If the reading is within the standard, remove the ECU and check the wiring for continuity between harness connectors.

Special Tool - Hand Tester: 57001-1394

Disconnect the ECU and sensor connectors.
