Engine General Information and Diagnosis:
Detected Failure Condition
The sensor voltage should be the following for
2 sec. and more, after ignition switch is turned
ON.
0.2 V ≤ Sensor voltage < 4.8 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 produced,
but signal from ignition coil is interrupted 8
times or more continuously. In this case, the
code C24 (P0351), C25 (P0352), C26 (P0353)
or C27 (P0354) is indicated.
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 or its motor
locked.
The sensor should produce following voltage.
0.15 V ≤ Sensor voltage < 4.85 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.
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.
CKP sensor (pickup coil) signal is produced,
but fuel injector signal is interrupted 4 times or
more continuously. In this case, the code C32
(P0201), C33 (P0202), C34 (P0203) or C35
(P0204) is indicated.
Some failure exists in the fuel injector signal in
a high load, high revolution condition. In this
case, the code C36 (P1764), C37 (P1765),
C38 (P1766) or C39 (P1767) is indicated.
The circuit voltage of motor drive is unusual.
Idle speed is lower than the desired idle
speed.
Idle speed is higher than the desired idle
speed.
