Engine General Information and Diagnosis:
Detected Failure Condition
No voltage is applied to the fuel pump,
although fuel pump relay is turned ON, or
voltage is applied to fuel pump although fuel
pump relay is turned OFF.
Voltage is applied to fuel pump although fuel
pump relay is turned OFF.
No voltage is applied to the fuel pump,
although fuel pump relay is turned ON.
No voltage is applied to the ECM.
Ignition switch signal is not input to the ECM.
* When the I.D. agreement is not verified.
* ECM does not receive communication signal
from the immobilizer antenna.
HO2 sensor output voltage is not input to ECM
during engine operation and running
condition.
(Sensor voltage > 1.0 V)
C44 (P0130) is indicated.
The Heater can not operate so that heater
operation voltage is not supply to the oxygen
heater circuit, C44 (P0135) is indicated.
EXCVA position sensor produces following
voltage.
0.14 V ≤ sensor voltage < 4.9 V
In other than the above range, C46 (P1675) is
indicated.
When no actuator control signal is supplied
from the ECM, communication signal does not
reach ECM or operation voltage does not
reach EXCVA motor, C46 (P1658) is
indicated. EXCVA can not operate.
EXCVA position sensor voltage is higher than
specified value.
EXCVA position sensor voltage is lower than
specified value.
When no operation voltage reaches EXCVA
motor, C46 (P1658) is indicated. EXCVA
motor can not be operated.
PAIR control solenoid valve voltage is not
input to ECM.
Cooling fan relay signal is not input to ECM.
EVAP system purge control solenoid valve
voltage is not input to ECM.

short
Fuel pump relay (coil side)
Lead wire/coupler connection
of ECM terminal to fuel fuse
Ignition switch, lead wire/
coupler, etc.
* Immobilizer/anti-theft system
HO2 sensor is circuit open or
shorted to the power source
Heated circuit open or shorted
to ground
Battery voltage supply to the
HO2 sensor
EXCVA, EXCVA lead wire/
coupler
EXCVA position sensor circuit
shorted to VCC or ground
circuit open
EXCVA position sensor circuit
open or shorted to ground or
VCC circuit open
EXCVA, EXCVA motor lead
wire/coupler
PAIR control solenoid valve,
lead wire/coupler connection
Cooling fan relay, lead wire/
coupler connection
EVAP system purge control
solenoid valve, lead wire/
coupler connection
