FUEL INJECTION SYSTEM
7-36
1
Throttle valve does not fully close.
•
Check the throttle body.
Refer to “THROTTLE BODY” on page 6-9.
•
Check the throttle cables.
Refer to “CHECKING THE THROTTLE
2
The ISC valve is stuck fully open due to a
disconnected ISC unit or coupler. (High
engine idle speeds are detected with the
ISC valve stuck fully open even though
signals for the valve to close are continu-
ously being transmitted by the ECU.)
•
Check the ISC unit screw for looseness or
disconnection.
•
Check the ISC unit coupler for disconnection.
•
The ISC valve is stuck fully open if it does not
operate when the main switch is set to
“OFF”.
(Make sure that the ISC unit vibrates by
touching it. If the ISC valve is vibrating, it is
working normally.)
3
ISC valve is not moving correctly.
•
Execute diagnostic code No. D54.
•
After the ISC valve is fully closed, the valve
opens to the standby opening position (posi-
tion when the engine is started). This opera-
tion takes approximately 3 seconds until it is
completed. Start the engine. If the error
recurs, replace the throttle body assembly.
Reinstatement method
Turn the main switch to “ON” and back to “OFF” to return the ISC
valve to its original position, and then start the engine.
After starting, let the engine run at idle speed for about 10 sec-
onds.
Fault code No.

Connections
•
Lean angle sensor coupler
•

•
Check the coupler for any pins that may be
pulled out.
•
Check the locking condition of the coupler.
