6-14CARBURETORS CARBNOTE:2. Check: throttle position sensor(removed from the carburetor)a. Disconnect the throttle position sensor cou-pler.b. Remove the throttle position sensor from thecarburetor.c. Connect the pocket tester (Ω 1k) to thethrottle position sensor.Tester positive probe blue 1Tester negative probe black/blue 2d. Measure the throttle position sensor maxi-mum resistance.Out of specification Replace the throttleposition sensor.Throttle position sensor maxi-mum resistance4.0 6.0 kΩ at 20C(blue – black/blue)e. Connect the pocket tester (Ω 1k) to thethrottle position sensor coupler.Tester positive probe yellow 3Tester negative probe black/blue 2f. While slowly opening the throttle, check thatthe throttle position sensor resistance iswithin the specified range.The resistance does not change or it changesabruptly Replace the throttle position sensor.The slot is worn or broken Replace thethrottle position sensor.Check mainly that the resistance changes grad-ually when turning the throttle, since the read-ings (from closed to wide-open throttle) may dif-fer slightly from those specified.Throttle position sensor resistance0 5 ± 1.0 kΩ at 20C(yellow – black/blue)
