DETECTED FAILURE CONDITION
The signal does not reach ECM for more than 4 sec. after re-
ceiving the starter signal.
The camshaft position sensor wiring and mechanical parts.
(Camshaft position sensor, intake cam pin, wiring/coupler con-
nection)
The signal does not reach ECM for more than 4 sec. after re-
ceiving the starter signal.
The crankshaft position sensor wiring and mechanical parts.
(Crankshaft position sensor, wiring/coupler connection)
The sensor should produce following voltage.
(0.5 V sensor voltage < 4.85 V)
Without the above range, c13 is indicated.
Intake air pressure sensor, wiring/coupler connection.
The sensor should produce following voltage.
(0.2 V sensor voltage < 4.8 V)
Without the above range, c14 is indicated.
Throttle position sensor, wiring/coupler connection.
The sensor voltage should be the following.
(0.15 V sensor voltage < 4.85 V)
Without the above range, c15 is indicated.
Engine coolant temperature sensor, wiring/coupler connection.
The sensor voltage should be the following.
(0.15 V sensor voltage < 4.85 V)
Without the above range, c21 is indicated.
Intake air temperature sensor, wiring/coupler connection.
The sensor voltage should be the following.
(0.5 V sensor voltage < 4.85 V)
Without the above range, c22 is indicated.
Atm. pressure sensor, wiring/coupler connection.
The sensor voltage should be less than the following for more
than 2 sec. after ignition switch turns ON.
(0.25 sensor voltage < 4.85 V)
Without the above value, c23 is indicated.
Tip over sensor, wiring/coupler connection.
Crankshaft position sensor (pick-up coil) signal is produced but
signal from ignition coil is interrupted continuous by two times or
more. In this case, the code c24, c25, c26 or c27 is indicated.
Ignition coil, wiring/coupler connection, power supply from the
battery.
