C24/C25
Ignition signal
CKP sensor (pick-up coil) signal is produced,
but signal from ignition coil is interrupted 8
times or more continuously. In this case, the
code C24 (P0351) or C25 (P0352) is
indicated.
Ignition coil, wiring/coupler
connection, power supply from
the battery
P0351/P0352
C28
STV actuator
When no actuator control signal is supplied
from the ECM, communication signal does not
reach ECM or operation voltage does not
reach STVA motor, C28 (P1655) is indicated.
STVA can not operate properly.
STVA motor, STVA lead wire/
coupler connection
P1655

connection
P1654
H Sensor voltage is higher than specified value.
STP sensor circuit shorted to
VCC or ground circuit open
L Sensor voltage is lower than specified value.
STP sensor circuit open or
shorted to ground or VCC
circuit open
C31
Gear position signal
Gear position signal voltage should be higher
than the following.

If lower than the above value for 3 seconds
and more, C31 (P0705) is indicated.
GP switch, wiring/coupler
connection, gearshift cam, etc.
P0705
C32/C33
Fuel injector
CKP sensor (pickup coil) signal is produced,
but fuel injector signal is interrupted 8 times or
more continuously. In this case, the code C32
(P0201), C33 (P0202) is indicated.
Fuel injector, wiring/coupler
connection, power supply to
the injector
P0201/P0202

speed.
Defective ECM
P0506
C40 Idle speed is higher than the desired idle
speed.
P0507
C41 FP 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. Fuel pump relay, lead wire/
coupler connection, power
source to fuel pump relay and
fuel injectors
C42
Ignition switch Ignition switch signal is not input to the ECM.
Ignition switch, lead wire/
coupler
