TC BOOST CONTROL SOLENOID VALVEPFP:14956
DescriptionEBS01KLY
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 (1) is moved by ON/
OFF pulse from the ECM. The longer the ON pulse, the charge air
pressure rises.

ECM Terminals and Reference Value
EBS01KM0
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.

1.CHECK OVERALL FUNCTION
1. Start engine and let it idle.
2. Make sure that turbocharger control actuator (1) 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 (1) har-
ness connector.
–: Vehicle front
–Alternator (2)
3. Turn ignition switch ON.
4. Check voltage between turbocharger boost control solenoid
valve terminal 1 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.
lHarness connectors E9, F4
lHarness for open or short between ECM and turbocharger boost control solenoid valve
lHarness for open or short between IPDM E/R and turbocharger boost control solenoid valve
>> Repair open circuit or short to ground or short to power in harness or connectors.

INTAKE AIR CONTROL VALVE CONTROL SOLENOID VALVE
INTAKE AIR CONTROL VALVE CONTROL SOLENOID VALVE
PFP:16188
DescriptionEBS01KM5
Vibration when stopping the engine can be controlled by cutting
intake air right before the fuel is cut. The intake air control valve con-
trol solenoid valve (1) controls the ON-OFF load of the intake air
control valve actuator. As a result, the intake air control valve control
solenoid valve will be turned ON when the ignition switch is turned
OFF with the engine running and when the engine stalls. After the
engine has stopped, the intake air control valve control solenoid
valve will return to fully open.
