Ignition
signal
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.
Ignition coil, wiring/coupler con-
nection, power supply from the
battery
P0351
32
Fuel injector 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.
Primary fuel injector, wiring/cou-
pler connection, power supply to
the injector
P0201
40
ISC valve 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.
ISC valve circuit open or shorted
to ground
Power source circuit open ISC
valve is fixed to full open
Disconnected ISC valve hose

44
HO2 sensor 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.
HO2 sensor circuit open or
shorted to ground
P0130
