Intake Air Control System -- On-Vehicle Inspection



1. CHECK INTAKE AIR CONTROL SYSTEM

  1. Check for leakage or clogging between the air cleaner housing and turbocharger inlet and between the turbocharger outlet and cylinder head.

    Condition
    		Operation
    Clogged air cleaner
    		Clean or replace element
    Hoses collapsed or deformed
    		Repair or replace
    Leakage from connections
    		Check each connection and repair
    Cracks in components
    		Check and replace


2. CHECK EXHAUST SYSTEM

  1. Check for leakage or clogging between the cylinder head and turbocharger inlet and between the turbocharger outlet and exhaust pipe.

    Condition
    		Operation
    Deformed components
    		Repair or replace
    Foreign material in passages
    		Remove
    Leakage from components
    		Repair or replace
    Cracks in components
    		Check and replace


3. CHECK TURBOCHARGING PRESSURE

  1. Warm up the engine.

  1. Using a 3-way connector, connect SST (turbocharger pressure gauge) to the hose leading to the intake air connector.

    Специальный инструмент (SST):
    09992-00242

  1. While depressing the clutch pedal, fully depress the accelerator pedal. Measure the turbocharging pressure at maximum speed (5,100 to 5,250 rpm).

    Standard pressure:
    53 to 61 kPa (0.54 to 0.6 kgf/cm2, 7.7 to 8.8 psi)
    If the pressure is less than the specification, check both the intake air and exhaust systems for leakage. If there is no leakage, check if the actuator hose has been disconnected. If it has not, check the turbocharger. If the pressure is greater than the specification, check if the actuator hose has been disconnected or cracked. If it has not, check the turbocharger.


4. CHECK TURBOCHARGER
ПРЕДОСТЕРЕЖЕНИЕ:
  1. Wear protective gloves to prevent injuries and burns when checking the turbocharger.
  2. The engine compartment becomes hot when the engine is running.

  1. Remove the No. 1 engine cover.

  1. Remove the 2 bolts and No. 1 turbo insulator.

  1. Using a 3-way connector, connect a vacuum gauge between the actuator and VRV.

  1. Warm up the engine.

  1. Measure the clearance between the stopper bolt and arm.

    Standard clearance:
    Engine Condition
    		Specified Condition
    Stopped
    		5.5 mm (0.217 in.)
    Idling
    		0.8 mm (0.031 in.)
    If the result is not as specified, adjust the length of the actuator rod.

  1. Measure the actuator pressure.

    Standard pressure:
    Engine Condition
    		Specified Condition
    Stopped
    		0 kPa (0 kgf/cm2, 0 psi)
    Idling
    		42.2 kPa (0.43 kgf/cm2, 6.1 psi)

  1. Check the operation of the arm.

    1. Check that the clearance between the stopper bolt and arm is 0.8 mm (0.031 in.) when the engine is idling.

    2. When fully depressing the accelerator pedal, check that the arm moves toward the fully closed position and then toward the fully open position.
