NOTE:
HO2 SENSOR VOLTAGE MEASURING CONDITION
1. 10 minutes after the engine start (Idling) or 100 sec. after the engine start (Engine revolution is over 2 000
r/min).
2. Coolant temperature is upper 45 ºC (113 ºF).
DETECTED FAILURE CONDITION
ITEM
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 condition.
(Sensor voltage
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.
