Is the throttle fitted after Lexus power failure?

After Lexus loses power, the throttle should be matched.

Many vehicles must use instruments to match after cleaning, replacing or replacing the throttle, so that the computer can remember the initial throttle signal. Based on this initial throttle signal, combined with other sensors, the fuel injection quantity of the engine can be controlled, the engine can be quickly accelerated, the fuel is quickly cut off, and the shift timing of the transmission can be controlled.

After the matching is completed, the engine and transmission can work normally. Otherwise, the engine will have high idle speed, idle driving and abnormal transmission.

Manual matching method:

1, start the engine.

2. Unplug the water temperature sensor (note: this water temperature sensor is connected to the computer, not the water temperature meter), and let the computer adjust the fuel injection amount according to the index that the engine water temperature has reached 80.

3. Unplug the air inlet pipe of the air filter and block the air inlet. Manually control the air intake to make the engine speed reach the normal idle speed (800 rpm) and keep it for about one minute.

4. Plug in the water temperature sensor again, and then loosen the blocked air inlet. At this time, the engine speed rises, but it will immediately control the idle speed to drop suddenly according to the signal of the water temperature sensor (that is, the actual water temperature of the engine). If the engine is already at normal temperature, the idle speed will be normal, and the manual matching is completed.
