TROUBLESHOOTING HINTS
Since the results of the inspection of the
charger waste gate solenoid harness and single
parts are normal, the following troubles can be in-
ferred if there is some trouble such as poor
ration, etc.
(1) Malfunction of the overboost pressure control
system
(2) Poor intake air hose connection
(3) Malfunction of turbo charger, turbocharger
waste gate solenoid
(4) Clogging of exhaust gas system
