Loulan, where is the throttle?

Loulan throttle should be above the air inlet of the engine intake pipe.

In a general car, the throttle valve is on the intake pipe of the engine, above the air inlet of the engine intake pipe.

The throttle valve is located behind the air cleaner element of the intake system and in front of the intake manifold.

The following are the methods to remove and clean the throttle (for reference only):

Step 1: Prepare tools, including a 10 small wrench (disassembling the battery terminal), a large Phillips screwdriver (disassembling the air inlet elbow) and a T30 internal wrench (disassembling the throttle valve).

Step 2: Remove the throttle inlet elbow.

Step 3: Unplug the throttle harness plug.

Step 4: Remove the throttle body.

There are two ways to clean the throttle. You can remove the throttle and clean it directly in the car. It is more convenient to remove and clean. If the throttle is dirty, just use a toothbrush. Don't spray it on the throttle shaft when cleaning, otherwise it will damage the throttle. When washing the car, spray it on cotton cloth to wipe the throttle and clean up the carbon deposit. Finally, as long as the throttle is matched, the idle speed will be higher just after cleaning.

When cleaning the throttle valve, it is not necessary to disassemble it, but the sealing part of the inlet steam must be cleaned, and the idle motor must be disassembled for cleaning. There are advantages and disadvantages of cleaning nozzles by borrowing and disassembling. Generally speaking, the maintenance station suggests disassembling and washing, which can prevent other unnecessary waste, such as replacing the sealing ring after disassembling or installing other gaskets, or delaying the owner's time because of oil and gas leakage when disassembling.

After cleaning, the throttle will be initialized according to the disassembly procedure just now. After cleaning the throttle, it needs to be initialized, because the computer has a memory function when adjusting the throttle opening, because there was sludge blockage in the past. In order to ensure the air intake, the computer will automatically adjust the throttle opening to make the air intake in a normal state.
