INSPECT TURBOCHARGING PRESSURE
Using a 3-way connector. connect SST (turbochar-
ger pressure gauge) to the hose between the vacuum
pipe and turbo pressure sensor.
SST 09992-00241
While driving in 2nd gear with the engine running at
4,000 rpm or more with the throttle valve fully open.
check the turbocharging pressure.
Standard pressure:
82 —- 115 kPe
(0.84 — 1.17 kgf/cm‘, 11.9 — 16.7 psi)
If the pressure is less than that specified. check the
intake air, VSV and exhaust systems for leakage. If
there is no leakage, replace the turbocharger assem-
bly and/or VSV.
If the pressure is above specification. check if the
actuator hose is disconnected or cracked. If not. re-
place the turbocharger assembly.
