NEEC0043The following are the major sensor reference graphs in ªDATA MONITORº mode.
(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
rise after ªCLSD THL POSº is changed from ªONº to ªOFFº.
