8-7 Periodic Maintenance and Adjustment
1. Idle speed stepper motor
2. Air damper degree sensor
3. Air damper
Air damper
For the purpose of adjustment of air intake
volume.
Idle speed stepper motor
To stabilize the idle speed
Fuel injector
Inject the fuel into the cylinder
Intake air temperature sensor
Inspect engine intake air temperature,
according to the temperature, the ECU will
automatically adjust the fuel injection volume.
Air intake pipe pressure sensor
Replace this entire paragraph with:
For testing the negative pressure of the air
intake pipe the engine will have two different
working conditions. Opening the air damper
and testing the pressure of the air intake can
change engine performance. The ECU is
designed to adjust the fuel injection volume
according to the negative pressure when
