C23 (P1651)
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 < 4.6 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 (P0351)/
C25 (P0352)
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) or C25 (P0352) is indicated. Ignition coil, wiring/coupler con-
nection, power supply from the
battery
C28 (P1655)
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
C29 (P1654)
STP sensor The sensor should produce following
voltage.
0.1 V < sensor voltage < 4.88 V
In other than the above range, C29
(P1654) 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(P0705)
Gear posi-
tion signal When gear position switch voltage is
as follows.
GP switch voltage > 0.2 V for 4 sec.
and more
When gear position switch voltage is
neutral and switch voltage is as follows.
GP switch voltage 4.77 V for 4 sec.
and more
If lower than the above value, C31
(P0705) is indicated
GP switch, wiring/coupler con-
nection, gearshift cam, etc.
