DTC P0045 TC BOOST CONTROL SOLENOID VALVEPFP:14956
DescriptionEBS011O7
The turbocharger boost control solenoid valve controls vacuum sig-
nal to the turbocharger boost control actuator. By changing the vari-
able 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 LogicEBS011TP
DTC Confirmation ProcedureEBS011TQ
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Start engine and let it idle for at least 5 seconds.
4. If 1st trip DTC is detected, go to EC-1063, "
Diagnostic Proce-
dure" .
WITH GST
Follow the procedure “WITH CONSULT-II” above.

Specification data are reference valves, and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may damage the
ECM's transistor. Use a ground other than ECM terminals, such as the ground.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)
Diagnostic ProcedureEBS011OA
1. CHECK TURBOCHARGER BOOST CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT
1. Disconnect turbocharger boost control solenoid valve harness
connector.
2. Turn ignition switch ON.
3. Check voltage between turbocharger boost control solenoid
valve terminals 1 and ground with CONSULT-II or tester.
