CONSULT-II Reference Value in Data Monitor
Mode
NGEC0042
Remarks:
쐌 Specification data are reference values.
쐌 Specification data are output/input values which are detected or supplied by the ECM at the connector.
* Specification data may not be directly related to their components signals/values/operations.
(i.e., Adjust ignition timing with a timing light before monitoring IGN TIMING. Specification data might be displayed even when igni-
tion timing is not adjusted to specification. This IGN TIMING monitors the data calculated by the ECM according to the input signals
from the camshaft position sensor and other ignition timing related sensors.)
쐌 If the real-time diagnosis results are NG, and the on board diagnostic system results are OK, when diagnosing the massair flow sensor,
first check to see if the fuel pump control circuit is normal.
