DescriptionEBS011AF
The load from the turbocharger boost control solenoid valve controls
the actuator. By changing the variable nozzle vane opening through
the rods, the intake air volume is adjusted.
The turbocharger boost control solenoid valve is moved by ON/OFF
pulse from the ECM. The longer the ON pulse, the charge air pres-
sure rises.
On Board Diagnosis LogicEBS011AI
These self-diagnoses have the one trip detection logic.
The MI will not light up for these self-diagnoses.
NOTE:
If DTC P0234 is displayed with DTC P0652 or P0653, first perform trouble diagnosis for DTC P0652
or P0653. Refer to EC-1240, "
DTC P0652, P0653 SENSOR POWER SUPPLY" .
Overall Function CheckEBS011AJ
Use this procedure to check the overall function of the turbocharger. During this check, a DTC might not be
confirmed.
1. Start engine and let it idle.
2. Make sure that turbocharger control actuator rod moves slightly
when engine is started.
3. If NG, go to EC-1147, "
Diagnostic Procedure" .
