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 open or
shorted to VCC or ground circuit
open
L
Sensor voltage is lower than specified
value.
TO sensor circuit shorted to
ground or VCC circuit open
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) o
C27 (P0354) is indicated.
Igni ion coil, lead wire/coupler
connection, 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 properly or its
motor locked
STVA motor, STVA lead wire/
coupler
P1655
C29
STP sensor The sensor should produce following
voltage.
0.1 V sensor voltage < 4.8 V
In other than the above range, C29 is
indicated.
STP sensor, lead wire/coupler
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 posi-
tion signal
Gear position signal voltage should be
higher than the following for 3 sec. and
more.
Gear position sensor voltage > 0.2 V
If lower than the above value, C31
(P0705) is indicated.
GP switch, lead wire/coupler
connection, 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
