Inlet throttle valve fault adaptives. Then turn OFF ignition switch and wait 40 seconds.
Check the connections of the inlet throttle valve.
Check the ECM connections.
Repair if necessary.
Check the continuity and insulation from vehicle body ground of the following connections:
• Between "C75-3" wire of inlet throttle valve connector and "C86-40" terminal of ECM connector
• Between "C75-2" wire of inlet throttle valve connector and "E33-6" wire of main relay mounting connector
• Between "C75-4" wire of inlet throttle valve connector and "C86-27" terminal of ECM connector
Repair if necessary.
If the fault persists, replace the inlet throttle valve.
