——engine idling speed actuator doesn’t work
——shorted fuel injector +12V circuit
——opened or shorted ignition coil circuit
also, monitor the following failure：
——with engine cycling start or engine working,
signal wheel is not synchronous.
——opened or shorted λsensor circuit
——opened fuel pump circuit
If a sensor failure(except the speed sensor/ TDC sensor) is
indicated, ECU will substitute the preset value for the input data
from the faulted sensor to keep engine operating. Also ECU
will store the failure in the memory permanently. At the same
time, the sensor will be kept out of the system until the sensor
signal matches the signal from ECU again.
If the actuator or the corresponding signal channel fails,
the above program is also applied.
When a failure is detected and the corresponding substitute
value is applied, the warning light on the instrument panel will
turn on.
Warning light will go out only when the component was
replaced by the dealer or the failure is non long-term .
No matter whether the failure is long-term, the failure data
will be stored permanently in the memory.
