1)CHECK THE ISA(IDEL SPEED ACTUATOR) CIRCUIT.
Showing of defects codes by MIL
CHECKING CIRCUIT
Coupler terminal is based on the side of the wire-harness
CHECK PROCEDURE
1) Turn off ignition key .
2) Check to see if the ISA(Throttle Position Sensor) coupler is loose,
or bad.If there is no defect, measure the input voltage of ISA
3) Disassemble the coupler of ISA, measure the resistance
between ISA terminals.
ISA resistance : 31.5~ 38.5[
],20
remarks : Measuring unit of resistance : Resistance ‘R’[
]
4) If there is no problem, check about the level of electricity flow between each terminal,
and between each ground.
Resistance between each terminal , and between each ground :
∞
[
]
If measure resistance value is not normal, replace with the new one
Disassembly and Assembly : refer to ( 5-23 )
remarks : Measuring unit for resistance : Resistance ‘R’[
