4-46 FI SYSTEM DIAGNOSIS Step 2 2 1) Turn the ignition switch OFF. 2) Disconnect the TP sensor coupler and ECM coupler. 3) Install the test harness to the TP sensor. 4) Check the continuity between terminal A and ground. TP sensor continuity: ∞ Ω (Infinity) (Terminal A – Ground) 5) If OK, then measure the TP sensor resistance at the test har- 2 ness terminals (between terminal A and terminal B). 6) Turn the throttle grip and measure the resistance. TP sensor resistance Throttle valve is closed: Approx. 1.1 kΩ Throttle valve is opened: Approx. 4.3 kΩ 2 E L P P/B M TPS R ECM SA B/Br 7) If OK, then measure the TP sensor resistance at the test har- 2 ness terminals (between terminal c and terminal D). TP sensor resistance: Approx. 4.68 kΩ (Terminal C – Terminal D) 09900-25008: Multi-circuit tester set 09900-28630: TPS test wire harness Tester knob indication: Resistance (Ω) Are the continuity and resistance OK? 2 YES Go to Step 3. NO • Reset the TP sensor position correctly. • Replace the TP sensor with a new one. P/B 8) After repairing the trouble, clear the DTC using SDS tool. TPS R ECM (4-27) B/Br
