Engine General Information and Diagnosis:
Detected Failure Condition
—
Althaugh the intake pressure is fluctuated, the
signal does not reach ECM for 3 sec. or more.
The sensor should produce following voltage.
0.24 V ≤ sensor voltage < 4.10 V
In other than the above range, C13 (P0105) is
indicated.
Sensor voltage is higher than specified value.
Sensor voltage is lower than specified value.
The sensor should produce following voltage.
0.35 V ≤ sensor voltage < 4.90 V
In other than the above range, C14 (P0120) is
indicated.
Sensor voltage is higher than specified value.
Sensor voltage is lower than specified value.
The sensor voltage should be the following.
0.2 V ≤ sensor voltage < 4.9 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 speed sensor signal is not input for more
than 3 sec. during the engine is running at 5
000 r/min or more.
The sensor voltage should be the following.
0.2 V ≤ sensor voltage < 4.9 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 for
2 sec. and more, after ignition switch is turned
ON.
0.17 V ≤ sensor voltage < 4.70 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.
No ignition signal is detected for 0.5 sec.
In this case, the code C24 (P0351) is
indicated.
