Intake Charge Pressure Check
WARNING: This page is about a different variant/trim than selected.
- Disconnect the hose (black) from the turbocharger wastegate solenoid, and connect the pressure gauge to the hose. Cap the solenoid valve nipple after the hose (black) was disconnected.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.
- Drive at full-throttle acceleration in second gear and then measure the intake charge pressure when the engine speed is about 3, 000 r/min or more.
Standard value: 68 - 122 kPa (9.9 - 17.6 psi)
- If the intake charge pressure is lower than the standard value, check the following items for possible causes.
- Turbocharger wastegate actuator malfunction
- Turbocharger wastegate regulating valve malfunction
- Intake charge pressure leakage
- Turbocharger malfunction
- Turbocharger bypass valve malfunction
- When the intake charge pressure is higher than standard value, the intake charge control may be faulty. Therefore check the followings:
- Turbocharger wastegate actuator malfunction
- Turbocharger wastegate regulating valve malfunction
- Rubber hose of turbocharger wastegate actuator disconnected or cracked
