ON-VEHICLE SERVICE
TURBOCHARGER SUPERCHARGING PRESSURE CHECK <Turbo>
     CAUTION
     Two persons should be in the vehicle when the test is conducted; the person in the passenger seat should read the indications shown by the pressure meter.
   
  1. Disconnect the hose (white paint mark) from the turbocharger waste gate solenoid valve, and connect the pressure gauge to the hose. Plug the nipple of the solenoid valve from which the hose (white paint mark) has been disconnected.
  1. Drive at full-throttle acceleration in L range and then measure the supercharging pressure when the engine speed in about 3,000 r/min.
    2. Standard value: 59 - 84 kPa
  1. If the supercharging pressure deviates from the standard value, check the following items for possible cause.
    • Malfunction of the waste gate actuator
    • Leakage of supercharging pressure
    • Malfunction of the turbocharger
  1. When the indicated supercharging is more than standard value, supercharging control may be faulty, therefore check the followings.
    • Malfunction of the waste gate actuator
    • Malfunction of waste gate valve
    • Disconnection or cracks of the waste gate actuator rubber hose
