Step "A"

  1. Ensure IAC valve is connected. Check for DTCs. Ensure timing is correct, spark plugs and air cleaner are okay, and PCV system is operating properly. See SELF-DIAGNOSTICS - INTRODUCTION article. Connect tachometer.
  2. Set parking brake. Start engine and run at 3000 RPM with no electrical loads (headlights, blower motor, rear defogger, A/C and radiator cooling fan off) and transmission in Park or Neutral. When radiator cooling fan comes on, allow engine to idle. See IDLE SPEED SPECIFICATIONS (CIVIC D16Y5 ENGINE CVT)  table. If idle speed is as specified, procedure is complete. If idle speed is not as specified, go to next step.
  3. If idle speed is 760-860 RPM, EVAP system may be purging EVAP canister. To temporarily stop purging, increase engine speed to more than 1000 RPM. Slowly release accelerator and check idle speed. See IDLE SPEED SPECIFICATIONS (CIVIC D16Y5 ENGINE CVT)  table. If idle speed is as specified, procedure is complete. If idle speed is not as specified, go to next step.
  4. Turn ignition off. Disconnect EVAP purge control solenoid valve 2-pin connector. For EVAP purge control solenoid valve location, see SYSTEM & COMPONENT TESTING article. If idle speed is not as specified, remove idle adjusting screw cap located on top of throttle body. See Figure. Turn idle adjusting screw in 1/2 turn increments, until idle speed is as specified. See IDLE SPEED SPECIFICATIONS (CIVIC D16Y5 ENGINE CVT)  table. Check idle speed after each 1/2 turn. If vehicle is equipped with A/C, after adjustment, go to Step "B" .
