FI SYSTEM DIAGNOSIS 4-45Step 21) Turn the ignition switch to 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)(Terminal A – Ground) 09900-25008: Multi-circuit tester set09900-28630: TPS test wire harness Tester knob indication: Continuity test ()5) If OK, then measure the TP sensor resistance at the test harnessterminals (between terminal A and terminal B).6) Turn the throttle grip and measure the resistance. TP sensor resistanceThrottle valve is closed: Approx. 1.1 kΩThrottle valve is opened: Approx. 4.4 kΩ222TPSP/BRB/BrECM7) If OK, then measure the TP sensor resistance at the test harnessterminals (between terminal C and terminal D).
