INSPECT SYSTEM OPERATION
(a)
Inspect the throttle control motor for operating sound.
(1)
Turn the ignition switch ON.
(2)
When depressing the accelerator pedal, check the
running sound of the motor. Also, check that there
is no friction sound.
If operation is not as specified, check the throttle control motor
(see step 3), wiring and ECM.
(b)
Inspect the accelerator pedal position sensor.
(1)
Connect a hand–held tester to the Controller Area
Network Vehicle Interface Module (CAN VIM). Then
connect the CAN VIM to the Date Link Connector 3
(DLC3).
(2)
Check that the MIL does not light up.
(3)
When turning the accelerator pedal position sensor
lever to the full–open position, check that the
throttle valve opening percentage (THROTTLE
POS) of the CURRENT DATA showns the standard
value.
Standard throttle valve opening percentage:
60% or more
If operation is not as specified, check that the accelerator pedal
position sensor (see page
If not using a hand–held tester, measure the voltage between
terminals (VTA1–E2, VTA2–E2) of the ECM connector (See
page
(c)
Inspect the idle speed.
(1)
Start the engine and check that the MIL does not
light up.
(2)
Allow the engine to warm up to normal operating
temperature.
(3)
Turn the A/C compressor ON to OFF, and check the
idle speed.
Idle speed (Transmission in neutral): 700
±
50 rpm
NOTICE:
Perform inspection without an electrical load.
(d)
After checking the above (a) to (c), perform the driving test
and check that there is no sense of incongruity.

3.
INSPECT THROTTLE CONTROL MOTOR
(a)
Disconnect the throttle control motor connector.
(b)
Using an ohmmeter, measure the motor resistance be-
tween terminals M+ and M–.
Motor resistance: 0.3 to 100
Ω
at 20
°

°
F)
If the resistance is not as specified, replace the throttle body as-
sembly (see page
(c)
Reconnect the throttle control motor connector.
