Step 2
1) Turn the ignition switch OFF.
2) Disconnect the TP sensor coupler.
3) Install the test harness to the TP sensor.
4) Check the continuity between terminal A and ground.
 TP sensor continuity: ∞ Ω (Infinity)
5) If OK, then measure the TP sensor resistance at the test har-
ness terminals (between terminal A and terminal B).
6) Turn the throttle grip and measure the resistance.
 TP sensor resistance
Throttle valve is closed:
Throttle valve is opened: Approx. 4.3 kΩ
7) If OK, then measure the TP sensor resistance at the test har-
ness terminals (between terminal C and terminal D).
 TP sensor resistance: Approx. 4.68 kΩ
 09900-25008: Multi-circuit tester set
09900-28630: TPS test wire harness
 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.
8) After repairing the trouble, clear the DTC using SDS tool.
