NOTE:
If DTC U1000 or U1001 is displayed, first perform the trouble diagnosis for DTC U1000, U1001. Refer to

EC-651, "DTC U1000, U1001 CAN COMMUNICATION LINE"

The vehicle speed signal is sent to the combination meter from ABS actuator and electric unit (control unit)
through CAN communication line. The combination meter then sends a signal to the ECM through CAN com-
munication line.

Diagnostic Procedure

EBS00R36

CHECK VEHICLE SPEED SIGNAL OVERALL FUNCTION

With CONSULT-II

Lift up the vehicle.

Start engine.

Select “VHCL SPEED SE” in “DATA MONITOR” mode with
CONSULT-II.

Make sure that “VHCL SPEED SE” indication exceeds 10 km/h
(6 MPH) when rotating wheels with suitable gear position.

Without CONSULT-II

Lift up the vehicle.

Start engine.

Read vehicle speed with combination meter.
Make sure that vehicle speed indication exceeds 10 km/h (6 MPH) when rotating wheels with suitable
gear position.

OK or NG

>> INSPECTION END

>> GO TO 2.

CHECK DTC WITH ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT)

Check DTC with ABS actuator and electric unit (control unit), Refer to “TROUBLEDIAGNOSIS-BASIC
INSPECTION”, BR-70.

OK or NG

>> GO TO 2.

>> Repair or replace.

CHECK COMBINATION METER

Check combination meter function.
Refer to “METERS AND GAUGES”, EL-100.

POWER STEERING PRESSURE SENSOR

PFP:49763

Component Description

EBS00R37

Power steering pressure (PSP) sensor is installed to the power
steering high-pressure tube and detects a power steering load. This
sensor is a potentiometer which transforms the power steering load
into output voltage, and emits the voltage signal to the ECM. The
ECM controls the electric throttle control actuator and adjusts the
throttle valve opening angle to increase the engine speed and
adjusts the idle speed for the increased load.

IVT CONTROL SOLENOID VALVE

IVT CONTROL SOLENOID VALVE

PFP:23796

Description

EBS00R3C

SYSTEM DESCRIPTION

*: This signal is sent to the ECM through CAN communication line.

This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intake
valve.
The ECM receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant
temperature. Then, the ECM sends ON/OFF pulse duty signals to the intake valve timing control solenoid
valve depending on driving status. This makes it possible to control the shut/open timing of the intake valve to
increase engine torque in low/mid speed range and output in high-speed range.

COMPONENT DESCRIPTION

Intake valve timing control solenoid valve is activated by ON/OFF
pulse duty (ratio) signals from the ECM.
The intake valve timing control solenoid valve changes the oil
amount and direction of flow through intake valve timing control unit
or stops oil flow.
The longer pulse width advances valve angle.
The shorter pulse width retards valve angle.
When ON and OFF pulse widths become equal, the solenoid valve
stops oil pressure flow to fix the intake valve angle at the control
position.
