DETECTED FAILURE CONDITION
CKP sensor (pickup coil) signal is pro-
duced, but fuel injector signal is inter-
rupted several times (Front 50 times,
Rear 25 times) or more continuously.
In this case, the code C32 (P0201) or
C33 (P0202) is indicated.
The circuit voltage of motor drive is
unusual.
Idle speed is higher than the normal
condition.
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.
Ignition switch signal is not input to
ECM.
HO2 sensor output voltage is not input
to ECM during engine operation and
running condition.
(Sensor voltage < 0.45 V)
In other than the above value, 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.
PAIR control solenoid valve voltage is
not input to ECM.
