DETECTED FAILURE CONDITION
The sensor voltage should be the fol-
lowing for 2 sec. and more, after igni-
tion switch is turned ON.
0.2 V sensor voltage < 4.6 V
In other than the above value, 23
(P1651) is indicated.
Sensor voltage is higher than specified
value.
Sensor voltage is lower than specified
value.
CKP sensor (pick-up coil) signal is pro-
duced, but signal from ignition coil is
interrupted 10 times or more continu-
ously. In this case, the code 24
(P0351) is indicated.
CKP sensor (pickup coil) signal is pro-
duced, but fuel injector signal is inter-
rupted 10 times or more continuously.
In this case, the code 32 (P0201) is
indicated.
When the ISC operation voltage
remains at 1.0 V or lower continuously
for 2 sec. or longer.
Idle speed is higher than the normal
condition.
Ignition switch signal is not input to the
ECM.
HO2 sensor output voltage is not input
to ECM during engine operation and
running condition.
(Sensor voltage < 0.60 V)
In other than the above value, 44
(P0130) is indicated.
The Heater can not operate so that
heater operation voltage is not supply
to the oxygen heater circuit, 44
(P0135) is indicated.
