Is it necessary to clean the oil circuit when the throttle is dirty?

There is no need to clean the oil circuit.

Cleaning the throttle valve is relatively simple. Remove the intake pipe, four throttle fixing bolts and two cooling water pipes, then unplug the throttle position sensor and remove the throttle body for cleaning. After cleaning the throttle, use Nissan special diagnostic instrument to learn idle speed.

The throttle is like a person's throat. If the throat is blocked by a foreign body, breathing will naturally be uncomfortable. Cars are consumables. With the use, the throttle valve will be affected by carbon deposition or oil stains generated internally, which will lead to problems in the intake of the engine. At this time, there will be some adverse reactions of the vehicle, such as alarm by fault light, unstable idle speed, weak acceleration, increased fuel consumption and excessive exhaust gas. When this happens, it is necessary to clean the throttle.

Throttle, also known as throttle valve, is a valve that controls the intake flow of the engine and is also one of the important components of the engine fuel system. The throttle valve is usually installed in front of the intake pipe of the engine and connected with the engine body, also known as the throat of the engine.

There are two kinds of throttles, one is cable type and the other is electronic throttle. At present, most vehicles use electronic throttle. Through the throttle position sensor, the on-board computer ECU will control the throttle opening according to the energy required by the engine, thus adjusting the air intake.
