When the fast idle cam is turned by the secondary throttle valve actuator, the cam pushes the lever on the throttle valve shaft causing the throttle valve to open and raise the engine speed. When the engine has warmed up, depending on the water temperature and ambient temperature as shown in the following table, the fast idle is cancelled allowing the engine to resume idle speed.

1. Fast idle link lever; 2. Fast idle cam; 3. STVA
Note: The fast idle link lever opens throttle valve a little to increase the engine speed.
Fast idle rpm | Fast idle cancelling Water Temp. |
1500-2000 rpm | 40-50°C (104-122°F) |
If, under the above conditions, the fast idle cannot be cancelled, the cause may possibly be short-circuit in the ECT sensor or wiring connections or maladjusted fast idle.
