DETECTED FAILURE CONDITION
ITEM
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.
Sensor voltage is higher than specified
value.
Sensor voltage is lower than specified
value.
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.
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.
The sensor should produce following
voltage.
0.1 V < sensor voltage < 4.88 V
In other than the above range, C29
(P1654) is indicated.
Sensor voltage is higher than specified
value.
Sensor voltage is lower than specified
value.
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
and more
If lower than the above value, C31
(P0705) is indicated
