TC BOOST CONTROL SOLENOID VALVE
TC BOOST CONTROL SOLENOID VALVE
PFP:14956
Description
EBS0151I
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.
ECM Terminals and Reference Value
EBS0151J
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.

Diagnostic Procedure
EBS0151L
1.
CHECK OVERALL FUNCTION
1.
Start engine and let it idle.
2.
Make sure that turbocharger control actuator rod moves slightly
when engine is started.
OK or NG
OK
>> INSPECTION END
NG
>> GO TO 2.
2.
CHECK TURBOCHARGER BOOST CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT
1.
Turn ignition switch OFF.
2.
Disconnect turbocharger boost control solenoid valve harness
connector.
3.
Turn ignition switch ON.
4.
Check voltage between turbocharger boost control solenoid
valve terminal 2 and ground with CONSULT-II or tester.
OK or NG
OK
>> GO TO 4.
NG
>> GO TO 3.
3.
DETECT MALFUNCTIONING PART
Check the following.
●
Harness connectors F45, M71
●
Harness for open or short between ECM relay and turbocharger boost control solenoid valve
●
Harness for open or short between ECM and turbocharger boost control solenoid valve
>> Repair open circuit or short to ground or short to power in harness or connectors.

4.
CHECK TURBOCHARGER BOOST CONTROL SOLENOID VALVE OUTPUT SIGNAL CIRCUIT FOR
OPEN AND SHORT
1.
Turn ignition switch OFF.
2.
Disconnect ECM harness connector.
3.
Check harness continuity between ECM terminal 6 and turbocharger boost control solenoid valve terminal
1. Refer to Wiring Diagram.
4.
Also check harness for short to ground and short to power.
OK or NG
OK
>> GO TO 5.
NG
>> Repair open circuit or short to ground or short to power in harness or connectors.
5.
CHECK TURBOCHARGER BOOST CONTROL SOLENOID VALVE
Refer to
EC-1513, "Component Inspection"
.
OK or NG
OK
>> GO TO 6.
NG
>> Replace turbocharger boost control solenoid valve.
6.
CHECK INTERMITTENT INCIDENT
Refer to
EC-1309, "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT"
.
>> INSPECTION END
Component Inspection

TURBOCHARGER BOOST CONTROL SOLENOID VALVE
1.
Disconnect turbocharger boost control solenoid valve harness
connector.
2.
Apply 12V direct current between turbocharger boost control solenoid valve terminals.
3.
Check air passage continuity of turbocharger boost control sole-
noid valve under the following conditions.
Operation takes less than 1 second.
If NG, replace turbocharger boost control solenoid valve.
Removal and Installation
