Advice 1: How to adjust the fuel flow on the injector

Consumption of fuel a vehicle with a fuel-injected engine can be adjusted by making adjustments in the system. It is better to address to specialists of service centers where it is performed on special stands. But if you are fairly well versed in car device, you can try to eliminate some of the causes of high fuel consumption on their own.
How to adjust the fuel flow on the injector
Instruction
1
Check the injector to allow fuel its mechanical part in the "closed" position. The transmittance of gasoline can be caused by one injector seal (for motors with "Central injection"). To check, remove the nozzle cover and turn on the ignition.
2
Peremknite contacts "FP" and "+In" on Board diagnostic connector, the fuel pump should earn. Take a flashlight and watch for some time for the injector. If the throttle valve is dripping fuel, then failure of the sealing ring. Replace them.
3
Inspect the temperature sensor of the engine coolant (ТНW). Fuel consumption is calculated by the car computer on the basis of his testimony. If the sensor indicates the temperature is lower than it really is, fuel consumption will naturally increase. The sensor can be wrong due to faulty thermostat, air lock in the cooling system, breakage of the radiator. Check and eliminate the causes of these faults.
4
Adjust position sensor throttle, using a multimeter and a manual for your car. If it was originally billed incorrectly, it can lead to high idle speed, incorrect corner of an advancing of ignition and incorrect fuel / air mixture.
5
Check oxygen sensor (Oxygen Sensor), or rather the integrity of the system air supply. If it is damaged, then the sensor sees the extra air as a lean mixture, and the "automatic" adds the fuel.
6
Identify the presence of suction of excess air with an aerosol can of lighter fluid. Start the engine, direct the spray of aerosol into the possible location of damage in the "ripple". If such a leak is, the engine speed will increase.
7
Remove and inspect the spark plugs. Black soot on them indicates that the fuel mixture run rich, which leads to increased consumption of gasoline. A frequent reason is a dirty air filter. Change it.
8
Inspect the fuel line of the car, if the spark plugs are bright Nagar. This means that the fuel system is low pressure, the result is a reduction in engine power. The reason for low pressure may be wear on the fuel pump, a clogged filter or mesh. Eliminate them. To perform more complex work of adjusting fuel injection system motorists with little experience it is better to contact the service center.

Advice 2: How to adjust idle on the injector

The first signs of malfunction of the IAC are; floating engine speed, engine stop when switching off the transmission, higher revs on warm engine, low engine rpm on a cold engine. This can occur from excessive air flow. To regulate the flow in engines with fuel injection needs a computer that, given the evidence of a number of sensors, opens at a valve injector or injectors.
How to adjust idle on the injector
Instruction
1
Unplug the power supply system of the vehicle. Turn off "mass". The controller is performing on the operation of the engine, so if it is defective lamp "fault injector" will not burn. It consists of a stepper motor with a conical needle. The regulator is mounted on the throttle body, providing a predetermined amount of air bypassing a closed throttle, which sets the car's trip computer for even heating and stable operation of the engine.
2
Unscrew the screws securing regulator and remove regulator. The IAC is on the throttle body and attached with two screws. In some models the screws are filled with paint with varnish or reamed, then need to dismantle the throttle body and subsequent disassembly.
3
Wash boarding channel controller and blow it with compressed air. Disassemble the regulator with the caution that would not damage a winding of the regulator. Check out the guide sleeve, if the conical needle rotates freely with a gap, then the bushing should be replaced. Cone the needle should be no visible damage and scuffs. If you find damage, replace it.
4
Check the continuity of the presser spring. Meter check the continuity of winding of the regulator. Clean the contacts of the winding. Collect the IAC. Before installing it on the car measure the distance from the mounting flange of the regulator to the edge of the tapered needle, it should be equal to 23 mm. If the distance is greater or less, replace the needle.
5
Install the IAC valve to seat in the throttle body. Connect the control plug to the IAC valve. Turn on the power of the car. Start the engine and test it on different modes.

Advice 3: How to adjust the throttle position sensor

Sensor throttle position opens the damper and transfer the control information to the electronic engine control unit. The sensor is usually installed opposite the lever throttle control. Periodically, the throttle position sensor requires verification and appropriate setting.
How to adjust the throttle position sensor
You will need
  • - multimeter;
  • - the voltmeter;
  • - ohmmeter;
  • - the probe.
Instruction
1
The test sensor throttle position produce at the closed position of the damper. Observe the correct sequence of actions. Switch off the ignition. Install the damper position to the closed position (do not press the accelerator pedal).
2
Disconnect the connector of the sensor. Check the conductivity between the left two terminals of the sensor. If conductivity is absent, the sensor must be configured and adjusted.
3
Take a feeler gauge with a thickness of 0.4 mm between the lock lever and the lock screw of the throttle. With a multimeter (ohmmeter) check that the resistance between the aforesaid above the contacts was equal to infinity. Otherwise, we can conclude about the possible malfunction of the sensor. Before you change the throttle position sensor, try to set it up and adjust.
4
Sensor adjustment make also with the throttle closed and the ignition is off. Do not press the accelerator. Disconnect the connector position sensor throttle. Loosen the screws on the sensor without removing them completely.
5
Rotate the sensor until then while between the extreme left terminals of the device will not match the table to the value specified in the technical documentation. After reducing the parameters to tighten the screws on the sensor, hold the tool so that when tightening the screws he had not changed his position.
6
If you are not confident in their abilities or do not possess the necessary skills, leave the sensor setting the throttle position to a specialist workshop. Installation and configuration of the sensor is carried out initially at the factory, so that in the ideal embodiment, the sensor needs to re-tune only by trained professionals, of course, if you expect to ensure a high quality of adjustment. Incorrect setting detrimental to the efficiency of the engine.
