C24/C25
C26/C27
Ignition sig-
nal
CKP sensor (pick-up coil) signal is pro-
duced, but signal from ignition coil is
interrupted 8 times or more continu-
ously. In this case, the code C24
(P0351), C25 (P0352), C26 (P0353) or
C27 (P0354) is indicated.
Ignition coil, wiring/coupler con-
nection, power supply from the
battery
P0351/P0352
P0353/P0354
C28
Secondary
throttle valve
actuator
When no actuator control signal is
supplied from the ECM, communica-
tion signal does not reach ECM or
operation voltage does not reach
STVA motor, C28 (P1655) is indicated.
STVA can not operate.
STVA motor, STVA lead
wire/coupler
P1655
C29
STP sensor The sensor should produce following
voltage.
0.15 V sensor voltage < 4.85 V
In other than the above range, C29
(P1654) is indicated.
STP sensor, lead wire/coupler
connection
P1654
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 posi-
tion signal
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.
GP switch, wiring/coupler con-
nection, gearshift cam, etc.
P0705
C32/C33
Fuel injector 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.
Fuel injector, wiring/coupler con-
nection, power supply to the
injector
