2.
Turn ignition switch ON.
3.
Check voltage between ECM terminals 83 (APP sensor 1 sig-
nal), 91 (APP sensor 2 signal) and body ground under the fol-
lowing conditions.
4.
If NG, replace accelerator pedal assembly.

Description
EBS013NA
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
EBS013NB
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.)

On Board Diagnosis Logic
EBS013NC
This self-diagnosis has the one trip detection logic.
The MI will not light up for this self-diagnosis.
Overall Function Check
EBS013ND
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-173, "Diagnostic Procedure"
.
DTC No.
