pressure gauge) to the hose leading to the intake air con-
nector.

(c) While depressing the clutch pedal, press the accelerator
pedal down to the full. Measure the turbocharging pres-
sure at maximum speed (5,100 to 5,250 rpm).
Standard pressure:
15 to 45 kPa (0.15 to 0.46 kgf/cm
2, 2.2 to 6.5 psi)
If the pressure is less than specification, check both the intake
air and exhaust systems for leakage.
If there is no leakage, check if the actuator hose has discon-
nected. If not, check the turbocharger.
If the pressure is greater than specification, check if the actua-
tor hose has disconnected or cracked. If not, check the turbo-
charger.
4. INSPECT TURBO PRESSURE SENSOR
(a) Inspect power source voltage
(1) Disconnect the turbo pressure sensor connector.
(2) Turn the ignition switch ON.
(3) Using a voltmeter, measure the voltage between
connector terminals 3 (VC) and 1 (E2) of the wiring
