ITEM
DETECTED FAILURE CONDITION
CHECK FOR
C21
IAT sensor
The sensor voltage should be the fol-
lowing.
0.15 V < sensor voltage
4.85 V
In other than the above value, C21
(P0110) is indicated.
IAT sensor, lead wire/coupler
connection.
P0110
H
Sensor voltage is higher than specified
value.
IAT sensor circuit open or
ground circuit open.
L
Sensor voltage is lower than specified
value.
IAT sensor circuit shorted to
ground.
C23
TO sensor
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
4.8 V
In other than the above value, C23
(P1651) is indicated.
TO sensor, lead wire/coupler
connection.
P1651
H
Sensor voltage is higher than specified
value.
TO sensor circuit shorted to
VCC or ground circuit open.
L
Sensor voltage is lower than specified
value.
TO sensor circuit open or
shorted to ground or VCC circuit
open.
C24
Ignition sig-
nal
CKP sensor signal is produced, but
signal from ignition coil is interrupted 8
times or more continuously. In this
case, the code C24 (P0351) is indi-
cated.
Ignition coil, lead wire/coupler
connection, power supply from
the battery.
P0351
C32
Fuel injector
CKP sensor signal is produced, but
fuel injector signal is interrupted 4
times or more continuously. In this
case, the code C32 (P0201) is indi-
cated.
Fuel injector, lead wire/coupler
connection, power supply to the
injector.
P0201
C41
Fuel pump
relay
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.
In this case, the code C41 (P0230) is
indicated.
Fuel pump relay, lead wire/cou-
pler connection, power source to
the fuel pump relay and fuel
injector.
P0230
H
More than 8 V is applied to the injector
and fuel pump relay is turned OFF.
Fuel pump relay switch circuit
shorted to power source.
Fuel pump relay (switch side).
L
Less than 0.3 V is applied to the injec-
tor and fuel pump relay is turned ON.
Fuel pump relay circuit open or
short.
Fuel pump relay (coil side).
