    Q:

    Q:
    What should you do if the resistance is incorrect for the Idle Control Valve on the 2001 Nissan Xterra? Posted by Jacob R.
    A:
    If the resistance is incorrect, replace the IAC valve. If it's functioning correctly, remove the IAC valve to inspect the plunger for any sticking or seizure. If the IAC valve is in good condition, consider having the PCM diagnosed by a qualified repair facility if idle issues persist.
