FI SYSTEM DIAGNOSIS 4-29
Step 2
1) Remove the air cleaner box. ("5-15)
2) Turn the ignition switch OFF.
3) Disconnect the TP sensor coupler.
4) Check the continuity between

A and ground.
% TP sensor continuity: ∞ Ω (Infinity)
(

A – Ground)
5) If OK, then measure the TP sensor resistance (between

A
and

B).
6) Turn the throttle grip and measure the resistance.
% TP sensor resistance
Throttle valve is closed : Approx. 1.12 kΩ
Throttle valve is opened: Approx. 4.26 kΩ
! 09900-25008: Multi circuit tester set
& Tester knob indication: Resistance (Ω)
Are the resistance and continuity OK?
