Major Sensor Reference Graph in Data
Monitor Mode
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.

lªACCEL POS SENº should increase
while depressing the accelerator
pedal and should decrease while
releasing it.
lªC/SLEEV POS/Sº should increase
when depressing the accelerator
pedal and should decrease when the pedal is
released.
lªACT INJ TIMGº should increase
when depressing the accelerator
pedal and should decrease when
the pedal is released.

ECM Terminals and Reference Value
PREPARATION
The ECM is located beneath the heater unit. To access the ECM,
remove the center console under cover at the passenger side.
Perform all voltage measurements with all connectors con-
nected. Since the ECM harness connector cannot be accessed
from the backside, voltages should be measured by connecting
a break out box (SST) between ECM and ECM harness connec-
tor.
When measuring:
lUse extreme care not to touch 2 pins at the same time.
lNote that the data is for comparison and may not be exact.
lBe sure ECM unit is properly grounded before checking.

ECM INSPECTION TABLE
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
damage to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
