WASTEGATE VALVE CONTROL Diagnostic Procedure 35
1
INSPECTION START
2
CHECK OVERALL FUNCTION. 1) Start engine and warm it up sufficiently. 2) Perform self-diagnosis. Make sure that Code No. 34 is not displayed. 3) Stop engine. 4) Disconnect air passage hose to wastegate valve control solenoid valve and restart engine. 5) Make sure that boost pressure exists under the following conditions. At idle: Boost pressure should not exist. When accelerator pedal is quickly depressed and released: Boost pressure should exist.
O.K.
CHECK COMPONENT (Wastegate valve actuator). Refer to Electrical Components Inspection. (See page EF & EC-637.) If N.G., replace wastegate valve actuator.
N.G.

CHECK CONTROL FUNCTION. 1) Check voltage between E.C.U. terminal 11 and ground under the following conditions. Voltage: At idle: Battery voltage. When accelerator pedal is quickly depressed and released: Approximately 0 - 1.0V.
O.K.
Check air passage hose for clogging, cracks and proper connection.
N.G.

CHECK POWER SUPPLY. 1) Stop engine. 2) Disconnect wastegate valve control solenoid valve harness connector. 3) Turn ignition switch ON. 4) Check voltage between terminal (a) and ground. Voltage: Battery voltage.
N.G.
Check the following. - Harness connectors (F34, M36) (L.H.D. models) - Harness connectors (M11, E104) (L.H.D. models) - Harness connectors (F10, F15) (R.H.D. models) - Harness continuity between wastegate valve control solenoid valve and ignition switch. If N.G., repair harness or connectors.
