5-22 FUEL SYSTEM AND THROTTLE BODYFAST IDLEThe fast idle system is automatic type.When the fast idle cam is turned by the secondary throttle valveactuator, the cam pushes the lever on the throttle valve shaftcausing the throttle valve to open and raise the engine speed.When the engine has warmed up, depending on the water temperature,ambient temperature and lapsed time, the fast idle iscancelled allowing the engine to resume idle speed.Ambient Temp. Fast idle r/minFast idle cancellingtime–5 °C 1 500 – 2 000 r/min Approx. 35 sec.15 °C 1 500 – 2 000 r/min Approx. 17 sec.25 °C 1 500 – 2 000 r/min Approx. 11 sec.FAST IDLE ADJUSTMENT• Lift and support the fuel tank. (5-3)• Remove the air cleaner box. (5-13)• Start up the engine and run it in idling condition for warmingup at the water temperature of 80 – 90 °C.• Set the idle r/min to 1 300 r/min by turning the throttle stopscrew 1.• Check and adjust the TP sensor. (4-19)• Turn the ignition switch to OFF• Disconnect the TP sensor coupler 2 and install the test harness.• Start up the engine.• Measure the TP sensor output voltage at the wire terminals(between + P/B and - B/Br). TP sensor output voltage at idle position:Approx. 1.12 ± 0.05 VTPSP/BRB/BrECM 09900-25008: Multi-circuit tester set09900-28630: TPS test wire harness Tester knob indication: Voltage ()• Turn the ignition switch to OFF.• Disconnect the STVA coupler.• Turn the ignition switch to ON.• Open the secondary throttle valve fully by turning it with yourfinger.• With the secondary throttle valve held at this position, measurethe output voltage of the TP sensor.
