DETECTED FAILURE CONDITION
The pick-up coil signal does not reach ECU for more than 3 sec.
after ECU receiving the ignition switch signal.
In this case, the code C12 is indicated.
Pick-up coil wiring and mechanical parts.
(Pick-up coil, lead wire coupler connection)
The sensor should produce following voltage.
0.1 V sensor voltage
Without the above range for 2 sec. and more, C14 is indicated.
Throttle position sensor, lead wire / coupler connection.
The sensor voltage should be the following.
0.08 V sensor voltage
Without the above range for 2 sec. and more, C15 is indicated.
Engine temperature sensor, lead wire / coupler connection.
The sensor should produce following voltage.
