THROTTLE POSITION SENSOR
INSPECTION
THROTTLE POSITION SENSOR INPUT VOLTAGE
• Remove the right radiator cover. (!5-2)
• Disconnect the throttle position sensor coupler

1.
• Shift the transmission into neutral.
• Start the engine.
• Measure the throttle position sensor input voltage using the
multi circuit tester.
% Throttle position sensor input voltage:
B/G (

+ probe) – B/Br (

- probe):
4.5 – 5.5 V (2 100 r/min)
$ 09900-25008: Multi-circuit tester set
* Tester knob indication: Voltage (+)
• If the voltage is not within the specified value, replace the CDI
unit.
THROTTLE POSITION SENSOR COIL RESISTANCE
• Measure the throttle position sensor coil resistance using the
multi circuit tester.
% Throttle position sensor total of resistance:
4 – 6 kΩ (Bl – B)
% Throttle position sensor resistance:
When the throttle fully closed: 0.6 – 1.0 kΩ (Y – B)
When the throttle fully opened: 3.2 – 5.0 kΩ (Y – B)
$ 09900-25008: Multi-circuit tester set
, Tester knob indication: Resistance (Ω)
• If the resistance is not within the specified value, replace the
throttle position sensor assembly.
