5-40 FI SYSTEM
Step 2
1) Turn the ignition switch OFF.
2) Disconnect the TP sensor coupler.
3) Check the continuity between Yellow wire and ground.
 TP sensor continuity: ∞ Ω (Infinity)
4) If OK, then measure the TP sensor resistance at the termi-
nals (between Yellow wire and Black wire).
5) Turn the throttle grip and measure the resistance.
 TP sensor resistance
Throttle valve is closed : Approx. 1.1 kΩ
Throttle valve is opened: Approx. 4.4 kΩ
6) If OK, then measure the TP sensor resistance at the termi-
nals (between Blue wire and Black wire).
 TP sensor resistance: Approx. 4.66 kΩ
 09900-25008: Multi-circuit tester set
 Tester knob indication: Resistance (Ω)
Are the continuity and resistance OK?
YES Go to Step 3.
• Reset the TP sensor position correctly.
NO
• Replace the TP sensor with a new one.
7) After repairing the trouble, clear the DTC using SDS tool.
