Engine General Information and Diagnosis:
Detected Failure Condition
Gear position signal voltage should be higher
than the following for 3 seconds and more.
Gear position sensor voltage
If lower than the above value, C31 (P0705) is
indicated.
CKP sensor (pickup coil) signal is produced,
but fuel injector signal is interrupted 4 times or
more continuously. In this case, the code C32
(P0201), C33 (P0202), C34 (P0203) or C35
(P0204) is indicated.
Some failure exists in the fuel injector signal in
a high load, high revolution condition. In this
case, the code C36 (P1764), C37 (P1765),
C38 (P1766) or C39 (P1767) is indicated.
The circuit voltage of motor drive is unusual.
Idle speed is lower than the desired idle
speed.
Idle speed is higher than the desired idle
speed.
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.
