6E1-28 ENGINE AND EMISSION CONTROL SYSTEM (TBI FOR G10)
1. 1.5 V battery (6.0 V in total)
“A”
“B”
“C”
3) Arrange 4 new 1.5 V batteries in series (6.0 V in total).
With throttle lever in contact with plunger of ISC actuator, con-
nect these batteries to ISC actuator terminals and check ISC ac-
tuator for operation.
CAUTION:
D Make sure that connection is made correctly between
batteries and terminals. Also, voltage must not be ap-
plied for longer than 1 second, or a faulty condition will
occur.
D Make sure that connection is correct. Connecting to
other terminals may cause damage to closed throttle
position switch (idle switch).
D After inspection, be sure to check that CTP switch is
ON. If it is OFF, move ISC actuator again and turn CTP
switch ON.
When positive terminal is
connected to “E” terminal
while plunger is contracted: Plunger expands
When positive terminal is
connected to “D” terminal
while plunger is expanded : Plunger contracts
When an abnormality has been found in above checks 2) and 3),
replace.
CLOSED THROTTLE POSITION (CTP) SWITCH, IDLE
SWITCH (IN ISC ACTUATOR)
INSPECTION
1) Disconnect connector from ISC actuator.
2) Arrange 3 new 1.5 V batteries in series (4.5 V in total) and con-
nect these batteries to CTP switch terminals “A” and “B”.
Check voltage between terminals “B” and “C” under following
each condition.
Throttle lever is in contact with ISC
actuator plunger : 0 – 1 V
Throttle lever is apart from plunger : 3.5 – 5.5 V
If check result is not satisfactory, replace throttle lower body.
