Special tool
(A): 09900–25008 (Multi-circuit tester set)
(C): 09900–28630 (TPS test wire harness)
TP sensor continuity
∞ Ω (Infinity) (Terminal "C" – Ground)
5) If OK, then measure the TP sensor resistance at the test
harness terminals (between terminal "C" and terminal
"D").
6) Turn the throttle grip and measure the resistance.
