CONSULT-II Reference Value in Data Monitor
Mode
NEEC0042Remarks:
+Specification data are reference values.
+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.)

(Select ªMANU TRIGº in ªDATA MONITORº with CONSULT-II. ªTrigger Pointº is set to 100%, ªRecording
Speedº is set to MAX.)
THRTL POS SEN, ABSOL TH´P/S, CLSD THL POSNEEC0043S01Below is the data for ªTHRTL POS SENº, ªABSOL TH´P/Sº and ªCLSD THL POSº when depressing the accel-
erator pedal with the ignition switch ON.
The signal of ªTHRTL POS SENº and ªABSOL TH´P/Sº should rise gradually without any intermittent drop or
