The following are the major sensor reference graphs in ªDATA MONITORº mode.
(Select ªHI SPEEDº in ªDATA MONITORº with CONSULT-II.)
ACCEL POS SEN, C/SLEEV POS/S, ACT INJ TIMG
Below is the data for ªACCEL POS SENº, ªC/SLEEV POS/Sº and ªACT INJ TIMGº when revving engine quickly
up to 3,000 rpm under no load after warming up engine sufficiently.
Each value is for reference, the exact value may vary.

ECM Terminals and Reference Value
PREPARATION
Perform all voltage measurements with all the connectors con-
nected. Measure ECM terminal voltage at the nearest connector to
the sensors or actuators to be measured as accessing ECM termi-
nals from outside is impossible.
IUse extreme care not to touch 2 pins at the same time.
I Data is for comparison and may not be exact.
I Use care not to enlarge the opening to keep the seal in good
condition.
Be sure ECM unit is properly grounded before checking.

ECM INSPECTION TABLE
Remarks: Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
