7 - 36FITHROTTLE BODIESf. While slowly opening the throttle, check thatthe throttle position sensor resistance iswithin the specified range.The resistance does not change or itchanges abruptly → Replace the throttleposition sensor.The slot is worn or broken → Replace thethrottle position sensor.NOTE:Check mainly that the resistance changesgradually when turning the throttle, since thereadings (from closed to wide-open throttle)may differ slightly from those specified. 2. Adjust:• throttle position sensor angle a. Connect the throttle position sensor couplerto the wire harness.b. Connect the digital circuit tester to the throt-tle position sensor.c. Measure the throttle position sensor volt-age.d. Adjust the throttle position sensor angle sothe measured voltage is within the specifiedrange.e. After adjusting the throttle position sensorangle, tighten the throttle position sensorscrews. Throttle position sensor resis-tance0 ~ 5 ± 1.5 kΩ at 20 °C (68 °F)(yellow - black)Tester positive probe → blue terminal 1Tester negative probe → yellow terminal 2Throttle position sensor voltage0.63 ~ 0.73 V(yellow - blue)
