DETECTED FAILURE CONDITION
Gear position signal voltage should be
higher than the following for 3 seconds
and more.
Gear position sensor voltage > 0.6 V
If lower than the above value, C31
(P0705) is indicated.
CKP sensor (pickup coil) signal is pro-
duced, but fuel injector signal is inter-
rupted 4 times or more continuously. In
this case, the code C32 (P0201) or
C33 (P0202) is indicated.
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 cond tion.
(Sensor voltage 0.1 V)
In other than the above value, C44
(P0130) is indicated.
The Heater can not operate so that
heater operation voltage is not supply
o the oxygen heater circuit, C44
(P0135) is indicated.
PAIR control solenoid valve voltage is
not input to ECM.
