Engine General Information and Diagnosis:
Detected Failure Condition
The sensor voltage should be the following.
0.15 V ≤ Sensor voltage < 4.85 V
In other than the above range, C15 (P0115) is
indicated.
Sensor voltage is higher than specified value.
Sensor voltage is lower than specified value.
The sensor voltage should be the following.
0.15 V ≤ Sensor voltage < 4.85 V
In other than the above range, C21 (P0110) is
indicated.
Sensor voltage is higher than specified value.
Sensor voltage is lower than specified value.
The sensor voltage should be the following.
0.5 V ≤ Sensor voltage < 4.85 V
In other than the above range, C22 (P1450) is
indicated.
Sensor voltage is higher than specified value.
Sensor voltage is lower than specified value.
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.
