DETECTED FAILURE CONDITION
The sensor voltage should be the fol-
lowing.
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 fol-
lowing.
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 fol-
lowing for 2 sec. and more, after igni-
tion 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 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) or
C27 (P0354) 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.
