The Car ‘Mitsubishi Lancer” – survivor the Japanese car industry (now available for the tenth generation). It is appreciated for its ruggedness, reliability, good maintainability. Motorists also attract a good mix of price and quality and high consumer properties. Especially in demand on the secondary market Mitsubishi Lancer 9. Its production ended almost a decade ago, but he is still popular.
During the development of each new generation of designers are trying to eliminate defects inherent in the previous models. Many defects are eliminated, but unfortunately, new ones appear.
The Petrol burnt in the engine not just. For proper combustion requires a lot of air. And it needs to be in a certain quantitative proportion of gas. Gasoline is injected into the intake manifold through the injectors. The amount received through a special pipeline fuel regulated valve. This piece, installed in a special housing called the throttle node. This valve has the shape of a circular plate, covering the air duct. The larger the opening angle, the more air gets into the intake manifold, and will increase the momentum. Opening angle is adjustable just the gas pedal. Lancer throttle valve 9 is driven by a stepper motor. The opening angle of the sensor element registers the flap. It defines this parameter.
Choke itself – very reliable detail. It is understandable, because the state of the node depends on stable operation of the engine. Usually the throttle “Lanser-9” begins to demand attention no sooner than 180 thousand km. But much earlier, every 20 thousand km, it is advisable to carry out preventive cleaning to avoid problems in the future. Interruptions in the operation of the engine at idle and high idle almost always indicate a dirty throttle plate. The reason for this may be the increased release of oil through the crankcase ventilation system, clogged air filter, and a congenital defect of fastening of the damper, which will be discussed below. Often the malfunction or breakage of the sensor position of the flap or its actuator.

Because the item regulates the flow of air, it has a direct effect on the stability and quality of idling. It also defines the quality of the engine start. A characteristic feature of (not only for Mitsubishi Lancer 9, but also for many other vehicles with similar air supply system) – floating idle. There are also some jerks when driving at low speed.
Prevention is preferably carried out at least once a year. This work is simple, but may postpone possible repairs and will save in the future. Cleaning throttle “Lanser-9” carried on the vehicle, but it is much easier to do with the removed node. To do this, disconnect the heated hose and air pipe, and a sleeve air supply and the wiring from the stepper motor and position sensor throttle. For cleaning apply spray cleaner. What if its not? No problem – for this operation is suitable and induction cleaner. There is also a similar flap. The part need to process the whole air channel from the inside, paying special attention to the place of contact of the damper with the body. Most often, dirt accumulates there, causing shortages at idle.
After application, it is necessary to clean all internal surfaces of the throttle node with a soft cloth. Also using the cleaner handle hose supplying air from the inside. There are deposits of oil and dust. You should pay attention that the composition of cleaning products should not be too harsh components that can damage rubber seals and axle grease. After this we need to put everything back in place and check the operation of the throttle. If the problem with floating left blank, you can not do without repair.
The throttle unit of the vehicle “Mitsubishi Lancer” has a "congenital" disease, which sooner or later affects all generations. The fact that the rotation axis starts to move with backlash, simply to hang out together with the damper. Since it is in the closed position completely closes the air channel and with every movement she sort of rubs against the wall. Dirt is abrasive. As a result, gradually the flap is produced on the edges, and a gap, through which the sucked air.
There are two solutions to this problem – buy a new throttle unit, or to turn another valve. Together with the manufacture of new parts (“penny” throttle "Lanser-9” because he is with a diameter of five centimeters) shouldto pierce the throttle to the size of 50.5 mm. Standard parameter – 50 millimeters. Thus, you eliminate the production from the backlash of the throttle. After that you need to cover the molybdenum part of the point of contact of the valve and the inner side of the throttle. In addition, you will need to install axis on angular contact bearings eliminate the bias from the throttle. You can simplify the task and apply sealant between the flap and the housing. But this is a temporary measure, and the repair of the throttle – no more than a respite before the more serious repairs. Therefore, if you fix it, it already thoroughly.
One of the reasons for the unstable idle speed may not be correctly working throttle position sensor. "Lancer" the 9th generation is no exception. Typically, the diagnostics indicate an error, but check for a faulty sensor and you can own with the help of multimeter. To do this, check the voltage at terminal "1" pads of the sensor.
With ignition on, the voltage should be between 4.8-5.2 V. When the ignition is off and the throttle fully closed the resistance between terminals "2” and “3” sensor should be 0.9 to 1.2 ohms.
“Japanese” the throttle body gasket (“Lanser-9" in particular) has an interesting feature – it is asymmetrical. That is, when the improper installation of the holes in it are aligned with the channels in the throttle node. Furthermore, it will be a constant air leak in zakosciele the space, so the idle speed will increase to 2000. For proper orientation when installing the gasket is equipped with a special area on the right. It can be seen, if you look at the throttle unit from its mating plane to the intake manifold.
In the process of exploitation there is another characteristic fault – throttle ("Lancer-9” 1.6 in particular) bites (stopped) in the half-open position. Because of this increase the idle speed. To correct this problem, loosen the adjusting nut on the side of the throttle shaft and turn the set screw. After that, the damper should snap back to its original position (closed). Tighten the nut and check the operation of the device. Usually this phenomenon happens when the already mentioned development of the walls of the throttle node due to misalignment of the flap. For the IAC uses a special screw, closed the cap. They set idle to about 750 rpm.
Thus, throttle, “Lanser-9” – enough to charge a node of the motor vehicle. Its correct operation is provided in the first place timely prevention and proper adjustment.
